Impact Bearing tapered roller bearings are designed for use in a wide range of applications, including the automotive,tractor, and machine tool industries, and are available in both inch and metric dimensions. This is a separable typeof bearing. The inner ring (cone), along with the cage and rollers, is one assembly unit; the outer ring (cup) is theother assembly unit. This feature allows the bearings to be fitted separately and adjusted so that the optimumclearance or preload for each application is achieved.

Due to the inclined position of the tapered rollers, the contact lines between the rollers and raceways intersect at acommon point on the axis of the bearing. The contact surfaces of the raceways and tapered rollers are modified tolimit edge stresses. As a result of this modification and the large number of rollers, this bearing has high load-carryingcapacity and is designed to carry axial and radial loads simultaneously. Since a single bearing of this type can onlycarry axial loads in one direction, the bearings are usually mounted in pairs.
