Product Details

Description

The Paired Face-to-face Tapered Roller Bearing has tapered inner and outer raceways between which the tapered rollers are arranged and mounted in pairs, facing each other or back to back on a common double outer raceway. The tapered rollers are designed to be particularly suitable for adapting axial and radial combined loads commonly found in hubs or heavy duty rolling machines.

Feature

Tapered roller bearings are designed such that the apex of the cone of each roller coincides with the apex of the inner and outer races on the bearing axis, or the extensions of the raceways and rollers converge at a common point on the axis of rotation. This results in a true rolling motion of the roller on the raceway at each point on the roller. Tapered roller bearings support only radial and axial loads in one direction. The line contact between the roller and the raceway provides high bearing capacity for the bearing.
