Double direction tapered roller thrust bearings

Double direction tapered roller thrust bearings can support high bidirectional axial loads and are able to compensate a small eccentricity between shaft and housing, without negatively affecting their performance. The first design features two tapered housing washers, a flat shaft washer, two rows of tapered rollers and two two-pieced machined brass cages guided on the shaft washer. A spacer sleeve is arranged between the two housing washers in order to adjust the correct bench end play (BEP) requested by the customer. The second configuration features an intermediate washer with external housing centering.
