Detail Introduction :
Insert ball bearings by two sides with a sealed outer spherical ball bearing and casting (or steel plate stamping) bearing seat composition. The internal structure of the outer spherical ball bearing is the same as the deep groove ball bearing, but the inner ring of this bearing is wider than the outer ring, the outer ring has a truncated spherical outer surface, and the concave spherical surface of the bearing housing can be automatically adjusted.
With seat outer spherical bearing is a rolling bearing and housing combined in a bearing unit, most of the outer spherical bearings are made of spherical outer diameter, and with a spherical bore of the imported bearing seat installed together, the structure of a variety of forms, versatility and interchangeability is good.
At the same time, skf bearing with housing is also designed with certain alignment, easy to install, with double structure sealing device, can work in the harsh environment. Bearing seat is generally used casting molding. Commonly used seats have vertical seat, square seat, tab square seat, tab round seat, diamond seat, ring seat, slider seat, etc..
Insert ball bearings are a combination of grease-sealed deep groove ball bearings and various shapes of housings to form a high-precision component product. The bearing assembly can be mounted directly to the main body of the machine with a few bolts, has an alignment function, and can be greased, so it is a very easy product to install and use.
The main features of Insert ball bearings are
1、Quick and easy installation
Different locking methods allow quick and easy mounting of insert ball bearings on the shaft.
2、Adaptation to initial deviation
The spherical outer surface can be tilted in the housing to achieve initial misalignment.
3、Long service life
The different sealing solutions available provide a long service life for a variety of applications with high contamination levels.
4、Reducing noise and vibration levels
In cases where high requirements for noise and vibration levels are important, SKF bearings can be provided with appropriate shaft locking methods.
Application range of Insert ball bearings.
Insert ball bearings are grease-sealed deep groove ball bearings and various shapes of housing combination of high-precision component products. insert ball bearings are mostly used in rougher machinery, installation positioning is not precise enough, priority for the requirements of equipment and components simple occasions, such as for agricultural machinery, transport systems or construction machinery.
Different types and materials of the two assembled together, a variety of structural forms, versatility and interchangeability, can be applied to different working conditions and mechanical devices, can work in harsh environments. This type of bearing is suitable for simple support, the application field is relatively wide, involving various industries, commonly used in mining, metallurgy, shipping, agriculture, chemical industry, textile, printing and dyeing, conveying machinery, beverage machinery, engineering machinery, etc.
Insert ball bearings maintenance.
1、When the bearings run to a certain period or maintenance period, the bearings will all be dismantled and tested.
2, confirm the appearance of the inspection for damage, there is serious damage to the bearing should be eliminated, replaced with the same type.
3、Check, first use the photo and other methods to make a good record of the appearance, in addition to confirm the amount of remaining lubricant and sampling of lubricant, and then clean the bearings.
4、In order to distinguish whether the dismantled bearing can be used from scratch, we should check its standard accuracy, rotational accuracy, internal clearance and collaboration surface, raceway surface, holding frame and sealing ring, etc.
Insert ball bearings based on 62 and 63 series sealed deep groove ball bearings, but with convex outer ring, and in most cases with a specific locking device with an extended inner ring, can be quickly and easily mounted to the bearing on the shaft.
Skf bearings all have very high quality quality, with seat bearing is one of the very popular, this bearing is high precision, low noise, strict quality control, advanced high-tech design to achieve high load, with long life and high quality, the application range is also very wide.
The following are the details of Insert ball bearings.
Insert bearings should not operate at speeds above the limiting speed listed in the product table. This speed limit is set by the seal design.
For insert bearings with set screws or an eccentric locking collar, the permissible speed is also influenced by the shaft tolerance. Where using these bearings on shafts with tolerances other than h6, compare the speed values listed in the product table with those in table 1. The lower value is the permissible speed.
|Bearing size||Allowable speed of the shaft machined to tolerance level|
The permissible speed of insert bearings with 5-lip seals is valid under the following conditions:
outer ring temperature ≤ 60 °C (140 °F)
ambient temperature ≤ 25 °C (80 °F)
very light to moderate loads (P ≤ 0,05 C)
cast iron housing
For other conditions, contact SKF.
For applications operating at higher speeds that are approaching but still below the limiting speed, and where eccentric locking methods are not suitable, or where low vibration or quiet running is required, SKF recommends using one of three concentric locking methods – either SKF ConCentra insert bearings, insert bearings on an adapter sleeve, or insert bearings with a standard inner ring.
The permissible operating temperature for insert bearings can be limited by:
1.the dimensional stability of the bearing rings and balls
Where temperatures outside the permissible range are expected, contact SKF.
Bearing rings and balls
SKF insert bearings are heat stabilized up to at least 150 °C (300 °F).
Steel cages can be used at the same operating temperatures as the bearing rings and balls. For temperature limits of PA66 cages, refer to Polymer cages.
The permissible operating temperature for NBR seals is –30 to +100 °C (–20 to +210 °F). Temperatures up to 120 °C (250 °F) can be tolerated for brief periods.
Typically, temperature peaks are at the seal lip.
Temperature limits for the greases used in SKF insert bearings are provided in table 1. For temperature limits of other SKF greases, refer to Selecting a suitable SKF grease.
When using lubricants not supplied by SKF, temperature limits should be evaluated according to the SKF traffic light concept.
SKF insert bearings are supplied capped on both sides and are greased.
Greases for capped bearings
Insert bearings are filled with one of the following greases (table 1):
1.bearings with zinc-coated rings and stainless steel bearings
→ food-grade grease GFM, registered by NSF as category H1
The NSF registration confirms the grease fulfils the requirements listed in the US Food and Drug Administration's guidelines under 21 CFR section 178.3570 (lubricant acceptable with incidental food contact, for use in and around food processing areas).
GFM grease is American Halal Foundation (AHF) and 1K Kosher certified.
2.all other bearings
→ standard grease VT307
Grease life for insert bearings
is presented as L10, i.e. the time period at the end of which 90% of the bearings are still reliably lubricated
depends on the load, operating temperature and the ndm value (diagram 1)
The indicated grease life is valid for the following combination of operating conditions:
very light to moderate loads (P ≤ 0.05 C)
low vibration levels
Where the operating conditions vary, the grease life obtained from the diagram should be adjusted as follows:
vertical shafts → 50% of the obtained value
heavier loads (P > 0.05 C) → apply reduction factor (table 2)
|Load pressure||Attenuation coefficient|
The values for adjusting the grease life are estimates. Vibration can have a negative influence on grease life. The extent cannot be quantified, and the influence increases with increasing operating temperature.
Relubrication can extend bearing service life under any of the following conditions:
The bearings are exposed to high humidity or severe contamination.
The bearings accommodate normal or heavy loads.
The bearings operate for extended periods at high speeds or at temperatures above 55 °C (130 °F).
The bearings are subjected to high vibration levels.
To relubricate insert bearings that have lubrication holes, the following greases can be used:
SKF LGWA 2
SKF LGMT 2
SKF LGMT 3
If relubrication is needed, the relubrication intervals can be estimated by following the method explained under Estimating the relubrication interval for grease.
When relubricating, the shaft should be turned and the grease pumped slowly until fresh grease starts to escape from the seal(s). Excessive pressure from pumping too quickly can damage the seals. When machines and equipment are used for a limited period of time, SKF recommends relubricating each bearing at the end of the operational period, i.e. immediately before being laid up.
SKF insert bearings are designed to facilitate relubrication. They have two lubrication holes in the outer ring as standard, one on each side, positioned 120° apart.
Bearings without lubrication holes can be supplied on request (designation suffix W).
The following insert bearings are lubricated for life and cannot be relubricated. They do not have any lubrication holes:
1.Bearings with set screw locking:
with zinc-coated rings
made of stainless steel
2.Bearings with a standard inner ring without designation suffix B
3.Bearings with 5-lip seals
4、Mounting and dismounting
The bearings can be quickly locked onto the shaft by various methods depending on their design:
1.Set screw locking
Tighten the two set screws using a hexagonal key or torque key ( fig. 1 ).
Eccentric locking collar
Turn the eccentric locking collar in the direction of main rotation with a hook spanner ( fig. 1 ) and secure the collar by tightening the set screw using a hexagonal key or torque key.
SKF ConCentra locking
Tighten the set screws in the mounting collar using a hexagonal key or torque key ( fig. 1).
Adapter sleeve locking
Press the unit onto an adapter sleeve by turning the adapter sleeve lock nut with a hook spanner ( fig. 1 ).
The shaft seat should be within the tolerances listed in table 1.
Set screws / adapter sleeve lock nuts should be tightened to the torque values / tightening angles listed in the technical specifications for each bearing (product table). The tightening angles listed for bearings on an adapter sleeve are to be used as guideline values only, as it is difficult to establish an exact starting position.
For additional information about hook spanners, refer to bearing fitting tools under Mechanical tools for mounting and dismounting.
For additional information about mounting and dismounting insert bearings and assembling ball bearing units, refer to the SKF bearing maintenance handbook.
Assembling insert bearings into housings with fitting slots
Insert bearings can be assembled into pillow block housings by inserting them into the fitting slots in the housing and turning them 90° into position (fig. 5).
Swivelling the bearing into position should be done using a round piece of wood or pipe (fig. 6).
This is required to overcome and to feel the suitable alignment torque. A sufficiently high alignment torque ensures that the outer ring will neither rotate in the housing nor swivel against the housing in operation. A sufficiently low alignment torque is required so that the bearing is not damaged during assembly.
A suitable alignment torque between bearing and housing is crucial for reliable operation. Only combine SKF bearings and SKF housings. If you are lacking experience with determining a suitable alignment torque, use ready-mounted SKF bearing units or contact the SKF application engineering service.
When assembling insert bearings and housings always consider:
1.The housing should be firmly tightened and not move during assembly.
2.Eccentric locking collars should be removed from the bearing prior to mounting and reinstalled when the bearing is in position in the housing.
3.The locking device should face in the same direction as the recess in the housing for the end cover.
4.No relubrication hole in the bearing outside diameter should coincide with either of the fitting slots in the housing (fig. 7). Otherwise grease leakage may result or contamination might enter the bearing.
5.Misalignment between bearing and housing axis should not exceed 5°.
6.If the bearing has to be relubricated, make sure the relubrication holes in the outer ring coincide with the relubrication feature in the housing bore. The misalignment of the bearing relative to the housing should not exceed 2°, otherwise relubrication will not be possible (fig. 8).
SKF ConCentra insert bearings When mounting SKF ConCentra insert bearings, position the collar so that one set screw is directly opposite the slit in the sleeve.
Do not tighten the set (grub) screws until the bearing is positioned on the shaft. If the screws are tightened prematurely, the stepped sleeve may deform. No attempt should be made to remove the sleeve and the mounting collar from the bearing prior to mounting. To dismount SKF ConCentra insert bearings, loosen the set screws first. Then gently tap the edge of the sleeve on the collar side or the inner ring side face on the opposite side to loosen the lock (fig. 9).
Insert ball bearings complete guide.
Bearings have been used in all walks of life, skf bearings are more outstanding, this guide is mainly about the content of the insert ball bearings, if you want to know more about this content, then continue to read it.
1、What should be paid attention to when installing insert ball bearings?
When installing, according to its type and size, you can choose mechanical, heating or hydraulic methods to carry out. When installing insert ball bearings, the force applied to the outer spherical bearing with seat should never be transferred from one bearing ring to another through the rolling element, otherwise it may cause damage to the raceway. But in any case, can not directly knock the bearing ring, cage, rolling body or seals.
Fixed bearing seat bolts first do not tighten, to allow with seat outer spherical bearing jacket in the bearing seat can rotate, and then the bearing seat bolts tighten well. Similarly install the other end of the bearing and seat on the same shaft, turn the shaft a few turns, let the bearing itself automatically find the right position after.
Install the eccentric sleeve, first set the eccentric sleeve on the eccentric step of the inner sleeve of the bearing, and tighten it by hand in the direction of rotation of the shaft. Then insert the small iron rod into or against the countersink hole on the eccentric sleeve. Use a hand hammer to hit the small iron rod in the direction of shaft rotation. Make the eccentric sleeve firmly installed, and finally lock the hexagonal screw on the eccentric sleeve.
Before installing the outer spherical bearing with seat on the shaft, you must remove the fixing pin of the bearing jacket, and polish the surface of the journal smoothly, and apply oil to the journal to prevent rust and lubrication. Apply lubricant to the mating surface of the bearing housing and the bearing, and install the bearing into the bearing housing. Then put the assembled bearing and housing together on the shaft. Push it to the required position for installation.
2、What are the disassembly methods for insert ball bearings?
When disassembling bearings, care must be taken not to damage other machine parts, such as shafts and housings, because damage to other machine parts can jeopardize the compliance and life of the machine. Sometimes bearings are disassembled to protect or replace other machine components, which can continue to be used. In this way, the selection of the correct disassembly techniques and objects becomes a basic requirement to reduce the risk of bearing damage to ensure that the bearings can continue to be used.
Disassembly of bearings is a task with inevitable hazards and very high requirements to disassemble bearings with bases in a safe, correct and effective way. Loosen the locking screw on the bearing eccentric sleeve with an Allen wrench, then insert a small iron rod into the countersunk hole on the top cover eccentric sleeve and loosen the eccentric sleeve against the direction of rotation of the shaft. Loosen the bolt fixing the bearing seat, and remove the bearing together with the bearing seat from the shaft, note that before removing the bearing seat at one end of the shaft, the bearing seat bolt at the other end of the shaft should be loosened to avoid damage to the bearings at both ends.
3、Cleaning and maintenance of insert ball bearings?
When the bearing is dismantled and inspected, the appearance of the bearing should be recorded by taking pictures, etc. In addition, the amount of lubricant remaining should be confirmed and the lubricant should be sampled, and then the bearing should be cleaned. In order to distinguish whether the dismantled bearing can be used from scratch, we should check its standard accuracy, rotational accuracy, internal clearance and collaboration surface, raceway surface, holding frame and sealing ring. The effect of inspection can be distinguished by those who are used to bearings or know about bearings. If there is any damage, the bearings should not be used from the beginning and must be exchanged.
4、What are the characteristics of insert ball bearings?
(1) With automatic centering function
The outer diameter of the bearing and the inner diameter of the housing is a spherical fit, with automatic centering function between the two, can compensate for the installation error generated by the axis does not coincide and the deformation of the bottom surface of the installation.
(2) High load capacity
As the internal structure of outer spherical ball bearing is the same as 6200 and 6300 series deep groove ball bearing, so the outer spherical ball bearing with seat can not only bear radial load, but also can bear certain axial load. At the same time, the working noise of the bearing is small.
(3) Long service life
External spherical ball bearings with oil nozzle, can be relubricated, bearing outer ring with oil groove, can better ensure that the grease can be smoothly injected from the oil nozzle into the bearing, to ensure that in any working environment have perfect performance and long service life.
(4) Excellent sealing performance
Both sides of the outer spherical ball bearing are sealed with heat-resistant, oil-proof rubber seal and steel plate dust cover. The dust cover is assembled on the outer diameter of the inner ring of the bearing and rotates with the inner ring, which can effectively prevent external foreign matter from entering the bearing and resist external pressure to protect the bearing, this combination seal composed of seal ring and dust cover can prevent mud, dust and moisture from entering the bearing, and at the same time can prevent the grease inside the bearing from leaking out.
(5) Sturdy bearing seat
Bearing seat for the whole seat structure, bearing seat rigidity is very good, to prevent the bearing in the assembly of deformation, in any working conditions bearing seat are durable. Bearing seat can be made of gray cast iron, ductile iron and cast steel and other materials casting.
(6) The bearing can be easily locked on the shaft
There are four ways to lock the bearings on the shaft, the common method is to lock the two set screws on the elongated end of the inner ring, and also can use the locking sleeve, locking sleeve or eccentric sleeve to lock. These four methods can easily lock the bearing on the shaft.
(7) Bearing inner ring for special heat treatment
Inner ring groove and its surrounding parts need to be hardened and normal quenching, assembly of the elongated end of the inner ring of the set screw after high-temperature partial tempering to maintain toughness and impact resistance. Inner ring screw hole around the local high temperature tempering, the bearing to obtain better performance, can prevent the screw in the bearing work during the loosening, while the screw is very tight will not cause the inner ring burst.
(8) Unique design to prevent the outer ring from rotating
The outer ring of the bearing is equipped with a unique stop ball, the stop pin allows the bearing to automatically adjust the center, but also to prevent the outer ring from rotating, so that the bearing life longer.
(9) Bearing and housing are completely interchangeable
The bearing and bearing seat are precision machined, the bearing and bearing seat are completely interchangeable, so the bearing can be easily replaced at any time.
(10) Easy installation
The outer spherical ball bearing is pre-filled with enough high quality grease, and the inserted ball bearing can be mounted directly on the shaft, thus avoiding harmful substances from entering the bearing during the process of mounting the bearing unit.
5、How to choose the insert ball bearings?
The correct selection of insert ball bearings is an important part of the performance of the bearings and the normal operation of the host. From a variety of bearings and housings to choose a suitable to meet the requirements of the host with insert spherical bearing models need to consider many factors. The structure of the machine itself requires the support, the space and shaft size of the mounting area, the load to be carried by the bearing.
Bearing life and reliability requirements, working speed, bearing and shaft fit nature and fixing method, support position, configuration and axial expansion and contraction size, bearing and bearing seat fit nature, ambient temperature requirements, surrounding media, dust, moisture, water and other requirements, the importance of relubrication, noise, vibration requirements, bearing seat strength requirements.
6、What heat treatment skills are needed for bearings?
(1) Clean heat treatment
Heat treatment production constitutes waste water, waste gas, waste salt, dust, noise and electromagnetic radiation will cause pollution to the environment. To solve the environmental pollution problem of heat treatment, the implementation of clean heat treatment is one of the directions of heat treatment skills development in developed countries. In order to reduce SO2, CO, CO2, dust and cinder emissions, the use of coal as a fuel has been eliminated, the use of heavy oil is becoming less and less, the majority of light oil, natural gas is still the most ideal fuel.
(2) Fine heat treatment
Fine heat treatment has two aspects: on the one hand, according to the application requirements of the parts, materials, structural dimensions, the use of general knowledge of physical metallurgy and advanced computer simulation and testing skills to optimize the process parameters to achieve the desired function or maximize the potential of the material; on the other hand, to ensure the stability of the optimization process, so that the product heat treatment deformation becomes zero and product dispersion is very small or zero.
(3) Energy-saving heat treatment
Scientific production and power management is the most potential factor for the effective use of power, the establishment of a professional heat treatment plant to ensure full production, give full play to the capacity of the equipment is the selection of scientific management. In the heat treatment power structure, priority selection of primary power; the full use of waste heat, waste heat; the use of low energy consumption, short cycle instead of a long cycle, energy-consuming process, etc.
(4) less oxidation-free heat treatment
To choose the protective atmosphere heating instead of oxidation atmosphere heating to accurate control of carbon potential, nitrogen potential controlled atmosphere heating, heat treatment after the function of the parts to advance, heat treatment shortcomings such as decarburization, cracks, etc. greatly reduced, heat treatment after the amount of finish machining to reduce the amount of stay, improve the use of materials and machining power.
7、What is the basic structure of insert ball bearings?
The bearing with fixed base includes oil cup, drip nozzle, bearing shell, bearing slider, bearing base, bolt hole, bearing capsule, retaining ring, reinforcement screw, steel ball, outer ring device, adjustment controller, inner ring device, seal and fixed base. The oil-filled cup is connected to the drip nozzle, the steel ball is installed in the inner position of the outer ring device, and the adjusting controller is fixed in the position below the reinforcement screw.
The retaining ring is connected to the sealing ring, the inner ring device is mounted below the drip nozzle, the bolt holes are located on both sides of the bearing housing, the fixed base is mounted below the bearing base, and the fixed base is connected to the sealing ring. The convenient bearing with fixed base uses alloy material, long service life, small size, set up oil groove and oil hole, very good to improve the effect of lubrication, lighter wear on machinery, practicality is more prominent, saving production costs.
8、How to prevent the failure of the bearing with base?
As the bearing failure formation factors are more, and generated with the dynamic operation process, so to avoid the bearing failure, first of all, we must do a good job of bearing maintenance, monitoring, assembly and routine maintenance work, in order to achieve a high degree of control before the work of the bearing and in all aspects of the work process.
First, to do a good job of bearing assembly, bearing inner ring and journal should be reasonable with the amount of interference with the design requirements, to avoid the interference is too small to lead to sliding friction between the inner ring and the shaft and heat, and to avoid the interference is too large to lead to the bearing clearance is too small to cause the inner ring raceway broken, so that the rolling body can not freely rotate and jammed phenomenon.
Second, before the bearing assembly to check whether the bearing parts are no quality defects, and after the assembly carefully test whether free rotation without noise, no resistance.
Third, to regularly add grease to the bearing, between filling to ensure that the quality of the grease itself meets the standard requirements, and check that there are no particles in the grease before filling, grease filling star to strictly comply with the design requirements of the bearing, to ensure that the bearing can be in the best working condition, and at the same time do a good job of sealing the bearing to prevent grease overflow.
Fourthly, the bearing grease samples should be taken regularly, and the bearing should be unloaded in time after hard particles are found in the grease, cleaned with clean gasoline or acetone and refilled with clean grease, and then re-installed for use.
Do a good job of bearing maintenance work, and its common types of failure to do a good job of prevention and maintenance work after the fact, you can extend the service life of the bearing, to ensure the smooth processing of bearings can be run in the best condition and prevent the occurrence of safety accidents.
