Single Direction Tapered Thrust Bearings


RKB Single direction tapered roller thrust bearings are produced in three different designs.

The first RKB Single direction Tapered Roller Bearings features a shaft washer with a tapered raceway, a two-piece machined brass cage, one row of tapered rollers, and a flat housing washer. They have a detachable design so, washers and cage-tapered roller assembly can be mounted separately. RKB Single direction Tapered Roller Bearings can accommodate axial forces only in one direction and can accept a small eccentricity between shaft and housing without compromising their performances. The second design has two identical tapered washers and a two-piece machined brass cage. It has a detachable design, so washers and cage-tapered roller assembly can be mounted separately. This configuration is normally suggested were heavy axial loads acting only in one direction have to be supported. On request for increased carrying capacity, a full complement (cageless design) can be manufactured. Bearing TKSD design for the screw-down mechanism is subjected to extremely heavy axial loads in one direction, and, to maximize the load-carrying capacity, RKB Tapered Thrust roller bearings usually is the full complement (cageless).

Moreover, they have to able to permit angular movement of the screw spindle respect to the support without affecting the bearing life negatively. The angular movement may be accommodated by one sphered washer, which can be either a shaft washer or a housing washer. RKB can supply the pressure plate. The 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.
