RKB 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 tapered rollers, this bearing has also a high rigidity. RKB Tapered Thrust Roller Bearings 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-piece 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, caged tapered rollers assemblies, and spacer sleeves can be mounted separately. RKB bearing Industries design and developing Tapered Thrust Roller Bearings up to 1600 mm Outer Diameter. All RKB Tapered Thrust bearings comply with ISO 104:2002 and ISO 199:2005.
