Tapered roller bearing cups, or bearing races, are the outer ring around which the bearing rides. Combine roller bearing cups with tapered roller bearing cones to create tapered roller bearings that allow you to carry maximum combinations of radial and thrust loads simultaneously.Roller spaced spalling from bearings operating after etching damage. True Brinelling. Bearing damage from shock or impact. Misalignment Damage. Irregular roller path from deflection, inaccurate machining or wear of bearing seats. High Spots In Cup Seats. Localized spalling on the bearing cup (outer race) from stress riser created by split.

Tapered roller bearings are uniquely designed to manage both thrust and radial loads. Consisting of a "tapered cup" and a "tapered cone", this design is one of the most basic and common styles in the bearing industry. Found in everything from cars to conveyor lines, tapered roller bearings are more versatile than any other bearing series.
