Kaydon RK series slewing ring bearing replacement

Introduction

RK Series bearings have a flanged cross-section on one or both rings and range in size from 20 – 47 inches OD (500 – 1200 mm). The flanged design reduces weight and provides the equipment designer greater flexibility for configuration of adjacent mounting structures and bolting arrangements. RK Series bearings are well suited for many applications where a large diameter and lighter weight are predominant factors in selection of a bearing.

Design Features

The internal configuration is a deep-groove gothic arch raceway, which provides four points of contact with the balls, enabling the bearing to simultaneously carry radial, axial, and moment loads. The use of spacer balls alternated with load balls allows for lower rotational torque and superior performance in applications involving oscillatory movement. Integral faceriding seals are provided to assist in the exclusion of contaminants. RK Series bearings are offered in non-geared, internally geared, and externally geared configurations for maximum design flexibility. The gears are Involute Stub designs with 20° pressure angles, manufactured to AGMA Class Q5 quality and .005 to .015 inches allowance for backlash. All models feature four fittings for lubrication, spaced 90 degrees apart. On non-geared and internal geared models, they are located on the outer counterbore diameter (Dr ). On external geared models, they are located on the inner counterbore diameter (dr ).

Application

RK Series bearings have been used successfully in a variety of light to medium duty applications including:

❚ Small cranes, booms, and lifts

❚ Industrial positioners and rotary tables

❚ Chute swivels

❚ Stretch wrapping machines

❚ Bottle filling machines

❚ Conveyors and related material handling equipment

❚ Rotating displays
