Product Details


A single such bearing can only withstand one direction of axial force, that is, limit the movement of the shaft in one direction. The paired use of the "back-to-back" configuration can withstand axial forces in both directions, limiting the movement of the shaft in both directions. So that the shafting is axially fixed. In addition, such bearings are subject to a radial load that produces a derivative axial force, and the use of a "back-to-back" configuration in pairs facilitates the balance of the derived axial forces.


1. When installing, pay attention to the bearing direction of the bearing. When installing the outer ring or inner ring of the bearing, it is best to use copper, wood or other soft material to pad on the shaft ring to prevent the bearing from being broken or deformed by the impact of strong and hard. Especially when hammering. At the same time, it is necessary to prevent it from being placed on the flower ring of the bearing.

2. To remove the burrs on the seat or shaft to be installed, guide the chamfer and apply grease or grease.

3. Bearings that are tightly coupled with the shaft should be installed after oil heating or electric heating.
