Taper Roller Thrust Bearings
- Tapered roller thrust bearings are a specialized type of thrust bearing designed to handle large axial loads (loads parallel to the shaft) with high stiffness and minimal axial space. 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. (TTC, TTHD, TTSP Series E.g.
