Front Axle Tapered Roller Bearing 1J0407625

Front Axle Tapered Roller Bearing 1J0407625 is a double row tapered roller bearing. When double row tapered roller bearings are subjected to radial load, the outer ring is fixed and the inner ring rotates with the shaft. 

As the rollers are tapered, their contact line with the raceways of the inner and outer rings is a straight line, which can transmit the radial force to the rollers. The roller rolls on the raceway between the inner and outer rings, and the radial force is dispersed by rolling friction, enabling the bearing to withstand large radial loads.

Product Specification

Reasons for low coefficient of friction:

1. The roller ends of the bearings have been optimized and the surface finish on the flanges is conducive to the formation of a lubricant film that reduces friction. This not only reduces frictional heat and flange wear, but also enables the bearings to better maintain preload and operate at lower noise levels.

2. The curved raceway profile of the basic design bearings and the logarithmic raceway profile of SKF Explorer bearings optimize the load distribution along the contact surfaces, reduce the tension peaks at the roller ends and reduce the sensitivity to misalignments and shaft bending, thus reducing friction.

3. The contact line between the rollers and the raceways of the inner and outer rings of double row tapered roller bearings is in a straight line, which enables the bearings to distribute the pressure uniformly when they are subjected to loads, improving the bearing capacity and service life, and reducing friction at the same time.
