Tapered Roller Thrust Bearing
Tapered roller thrust bearings are composed of shaft washer, housing washer, cage and tapered rollers. The design of tapered roller thrust bearings is made to the extent that cones of shaft washer, housing washer raceways and roller surface are intersected at one point of bearing central line. Therefore, the rolling surface can form a kind of bearing whose limit rotating speed is much higher than cylindrical roller thrust bearings. Tapered roller thrust bearings are accommodated with higher axial loads and peak loads. Meanwhile, they are stiff and with little axial space. In general, tapered roller thrust bearings have three kinds of housing washers, one is housing raceway with a rib, the other is without a rib, and the last is with full complement rollers. In ZWA, we only catered the customers with the first 2 types. Cages for tapered roller thrust bearings in ZWA are steel or brass ones.
