Taper Roller Bearings
Taper 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 type of bearing. The inner ring (cone), along with the cage and rollers, is one assembly unit; the outer ring (cup) is the other assembly unit. This feature allows the bearings to be fitted separately and adjusted so that the optimum clearance 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 a common point on the axis of the bearing. The contact surfaces of the raceways and tapered rollers are modified to limit edge stresses. As a result of this modification and the large number of rollers, this bearing has high load-carrying capacity and is designed to carry axial and radial loads simultaneously. Since a single bearing of this type can only carry axial loads in one direction, the bearings are usually mounted in pairs.
