• What does the number on the bearing mean

    The numbers on the bearing indicate the bearing model, bearing type, size, etc.Example:30206:3 represents tapered roller bearing, 0 represents width series 0, 2 represents diameter series 2, and 06 represents bearing inner diameter of 30mm.6203:6 rep......

  • Are there any differences between bearings 32315 and 32315b?

    Both are tapered roller bearings with the same inner diameter, outer diameter and width. The latter B is the "post code" of the bearing, indicating that the internal structure of this bearing is different from that of ordinary bearings. Spe......

  • How to calculate the friction torque of the bearing?

    One method of calculating the friction torque of rolling bearings is to divide the friction torque into independent parts, including the torque M0 which is not affected by the load and the torque M1 which depends on the load, and then add the two tog......

  • What is the pur***e of bearing heat treatment?

    (1) The application scope of GCr15 steel has been expanded. Generally, the effective wall thickness of the ferrule when GCr15 steel m is quenched is less than 12mm, but due to the strong cooling capacity of nitrate salt during BL quenching, if measur......

  • Where are bolt roller bearings used more?

    Basically not. This kind of bearing is mainly used in places with large shaft diameter and small bearing pedestal, where a small amount of axial series movement is required, but the speed is required to be low....
