You Need To Know Bearing Technology
- 99502h Bearing Cross Reference +
- In addition to single row bearings, 99502h bearings also have double row bearings, paired double bearings and four row bearings. The tapered roller shaft-holder generally adopts a stamping cage.
- Sta4195 Bearing Interchange +
- Bearings are basic components, and bearings are standard parts. Any mechanical equipment that needs to rotate requires bearings.
- TIMKEN 07100 Cross Reference +
- Timken 072100 tapered roller bearings are designed to accommodate combined loads, i.e.
- HM212049 Cross Reference +
- The HM212049 bearing under the TIMKEN brand is a component that fixes and reduces the friction coefficient of the load during the mechanical transmission process.
- NGK 8 Cross Reference +
- The spark plugs produced by NGK 8 are mainly used in Japanese cars. The model number of the NGK spark plug is printed on the ceramic insulator of the spark plug skirt and consists of a series of letters and numbers.
- R8RS Bearing Cross Reference +
- This R8-RS 1/2x1-1/8x5/16-inch sealed ball bearing has deep groove geometry for high speeds and supporting both radial and axial loads.
- 1635 Bearing Cross Reference +
- The bearing type of 1635 bearings is open deep groove ball bearing. It is generally composed of a pair of ferrules, a group of cages and a group of steel balls.
- STA4195 Bearing Cross Reference +
- KOYO STA4195 tapered roller bearing carry combinations of large radial and thrust loads. The axial load carrying capacity of the bearings is largely determined by the contact angle. The larger the angle, the higher the axial load capacity.
- 7r8 Bearing Cross Reference +
- 7r8 bearing is the most representative deep groove ball bearings with a wide range of applications. It is suitable for high-speed or even extremely high-speed operation, and it is very durable without regular maintenance.
- 6203lu Bearing Cross Reference +
- NSK 6203DUL1 bearings are the most widely used bearings and utilize an uninterrupted raceway, which makes these bearings suitable for radial loads, or a combination of thrust and radial loads.
