Double direction tapered roller thrust bearings (TTK) can support high bidirectional axial loads and are able to accommodate a small eccentricity between shaft and housing, without affecting negatively their performance.
Due to a large number of a tapered rollers, this bearing has also an high rigidity. TTK is available in two main configurations. The first one has two tapered housing washers, a flat shaft washer, two tapered rows of rollers and two two-pieced machined brass cage guided on 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. A second version has an intermediate washer with external housing centering. Both bearings designs are separable, so washers, cagetapered rollers assemblies and spacer sleeve can be mounted separately.
