SKF Bearings Components

Bearings generally consist of an inner ring, outer ring, rolling element, cage, and grease.

The inner ring, also known as the inner sleeve or inner ring is usually fixed on the shaft journal and the inner ring rotates with the shaft. There are grooves on the outer surface of the inner ring for the balls or rollers to roll, called the inner groove or inner raceway.

The outer ring is also known as the outer ring or outer ring is usually fixed in the bearing housing or machine shell, to support the role of rolling body. The inner surface of the outer ring also has for the steel ball or roller rolling groove, called the inner groove or inner raceway.

Rolling body also known as steel ball or roller, each set of bearings are equipped with a group or several groups of rolling body, installed between the inner ring and outer ring, the role of rolling each transfer of force. Rolling body is the load bearing parts, its shape, size and number determines the bearing ability to withstand the load of each high-speed operation performance.

Keep frame is also called keeper or isolator is mainly the rolling body in the bearing evenly separated from each other, so that each rolling body between the inner ring and outer ring to roll normally.

1, The inner ring usually fits tightly with the shaft and rotates together with the shaft.
2, The outer ring usually fits with the bearing housing hole or mechanical parts shell, playing a supporting role. But in some applications, there are outer ring rotation, inner ring fixed, or inner and outer ring are rotating.
3, rolling body with the cage evenly arranged between the inner and outer ring. Its shape, size and number directly affect the bearing capacity and performance.
4, The cage will be rolling body evenly separated, guide the rolling body in the correct track movement, improve the bearing internal load distribution and lubrication performance.
5, Used in the friction part of the machinery, play the role of lubrication and sealing. Also used in the metal surface, play a role in filling the gap and rust prevention.

2. Limitation of SKF Bearings

SKF bearing is a leading company in the bearing industry, can be said to be one of the most well-known bearing companies in the industry, the development and production of bearings have very high quality standards, its performance is very superior, is the long-term cooperation of many well-known enterprises brand, the use of SKF bearings will further improve the quality of equipment.

Nevertheless, SKF bearings also have some apparent limitations, the most direct is its price is relatively high, compared to other ordinary bearings, the price may not let all manufacturers are able to accept. In addition, there are also quite a lot of counterfeit SKF bearings on the market. if not carefully identified, it is very easy to buy fake goods lead to losses.

But this also proves from the side that the quality of SKF bearings is very reliable, is very worth using the brand, after all, the price and quality is always proportional.

3. How SKF Bearings Works

The working principle of bearings is relatively simple, as can be seen from the structure of the bearing: the ball with a smooth metal surface inside and outside, which helps to roll. The ball itself carries the weight of the load, and this weight-bearing force is what drives the bearing to rotate. However, not all loads exert force on the bearing in the same way. There are two main types of loads on bearings: radial and thrust.

Radial loads simply put weight on the bearing, making the bearing roll or rotate due to tension, thrust loads stress the bearing in a completely different way, the bearing flips on its side and is subjected to full force at that angle, this is called a thrust load, many skf bearings are easily subjected to radial and axial loads.

4.How to Verify Quality of SKF Bearings

Because SKF bearings in the international reputation, its quality has been recognized by the majority of manufacturers, so there are many counterfeit products, in order to avoid buying counterfeit bearings, you can identify from the following aspects: 1.
Surface oil stains: inferior bearings because the production process is relatively backward, and rust prevention technology is not advanced, so there will be a relatively heavy oil stains, cleaning inconvenience, genuine should be no oil stains no dirt clean and tidy.
2. steel printing word: SKF bearing in the production will use advanced steel printing technology engraved product information, clear lettering dents very deep, counterfeit products are blurred and floating on the surface.
3. noise: counterfeit bearings because of the production environment and production process backward will lead to the bearing into some impurities and thus the bearing will appear some noise, while SKF bearings are no noise.

5.Parts of SKF Bearings

The basic structure of the bearing is: by the inner ring, outer ring, rolling body (steel balls or rollers) and cage.
1. Inner ring: usually fixed on the journal, the inner ring and shaft together with the rotation.
2. Outer ring: usually fixed in the bearing housing or machine shell, to support the role of the rolling body.
3. Rolling body: each set of bearings are equipped with a group or several groups of rolling body, installed between the inner ring and outer ring, the role of rolling each transfer of force. Rolling body is the load bearing parts, its shape, size and number determines the bearing ability to withstand the load of the performance of high-speed operation.
4. Keep frame: the rolling body in the bearing evenly separated from each other, so that each rolling body between the inner ring and outer ring to roll normally.

6.How to Troubleshoot SKF Bearings

The most common failures are fatigue spalling (pitting), wear and galling.
1. Fatigue spalling (pitting): Under the action of alternating load, there is a large cyclic contact stress between SKF bearing surfaces, which can lead to the formation of fatigue sources on the surface. Fatigue sources produce micro-cracks, due to its high hardness and brittleness, micro-cracks are difficult to develop in depth, they flake with small particles and have good pitting on the surface. In severe cases, craters will be formed, and continued operation will result in extensive spalling, requiring the use of bearing failure detectors for diagnosis.

2. Wear: reduce SKF bearing running accuracy makes noise, mainly because of poor lubrication, external dust particles and other foreign objects invasion, improper transfer and other reasons.

3. Gluing: mainly because of lack of oil, lack of grease under the lubrication is insufficient, as well as heavy load, high speed, high temperature, rolling body and raceway in contact with the local high temperature metal welding phenomenon, once this failure equipment will often be difficult to run.

7.SKF Bearings Validation Documents

10.How much SKF Bearings Cost

The price of SKF bearings varies depending on the type of bearing, the price is usually between $1.5 and a dozen dollars, the price is relatively higher than ordinary bearings, but you have to believe that a penny is worth a penny, once invested can be used for life, SKF bearings have very strong superiority in the service life and maintenance costs and other aspects of significant advantages, although the price of SKF bearings is not the lowest, but the quality must be the highest in the industry. But the quality must be the highest in the industry.

11.SKF Bearings Maintenance Process

1. Disassembly: SKF bearings are disassembled for regular maintenance and bearing replacement. After disassembly, if you continue to use, or still need to check the state of the bearing, the disassembly should be carried out as carefully as the installation. Pay attention not to damage the bearing parts, especially the disassembly of interference fit bearings, the operation is difficult.

2. Cleaning: SKF bearing cleaning is divided into rough and fine cleaning, and can be used in the bottom of the container put on the metal mesh frame. Rough cleaning, in the oil with brushes and so on to remove grease or adhesion, fine cleaning, need to carefully in the oil slowly rotate the bearing. Usually use the cleaning agent for neutral water-free diesel oil or kerosene, according to the need sometimes also use warm alkaline liquid, etc.. No matter which cleaning agent is used, it should be filtered frequently to keep clean. After cleaning, need to immediately in the bearing coated with anti-rust oil or anti-rust grease.

12. How to Choose Grease for SKF Bearings?

Lubrication has an extremely important influence on the operation and life of SKF bearings. Grease is made of base oil, thickener and additives, and the performance of different types and different grades of the same type of grease varies greatly, and the allowed rotational limit is different.

The performance of grease is mainly decided by base oil, generally low viscosity base oil is suitable for low temperature and high speed, high viscosity is suitable for high temperature and high load. The thickener is also related to the lubrication performance, and the water resistance of the thickener determines the water resistance of the grease. In principle, different brands of grease can not be mixed, and even the same thickener grease, but also due to different additives to bring bad influence on each other.

13. What are the Requirements of SKF Bearing Installation?

1.Requirements for mounting surface and mounting place: If there are iron chips, burrs, dust and other foreign matter entering in SKF bearing, it will make SKF bearing noise and vibration during operation, and even damage the raceway and rolling body, so it must ensure the cleanliness of mounting surface and mounting environment before installing SKF bearing.
2.KF bearing must be cleaned before installation: SKF bearing surface coated with antirust oil, cleanliness of SKF bearing life and vibration noise is very big, with clean gasoline or kerosene carefully clean, and then coated with clean high quality or high speed high temperature lubricating grease before installation and use.
