TTHD bearings consist of two thrust races, a set of rollers and a cage. This design can create up to 40 percent more capacity than cylindrical and spherical bearings with the same envelope dimensions.The configuration of TTHD bearings creates a benefit called true rolling motion. The extensions of the raceways and rollers converge at a common point (the apex) on the axis of rotation. As a result, true rolling motion reduces heat generation and wear on the races and rollers.
