Internal Toothed Ball Slewing Ring

Similar in size to the RK series, Kaydon's HS series slewing ring bearings have rectangular cross sections that provide approximately twice the load capacity (moment ratings up to 139, 900 ft-lbs) in the same envelope. HS series bearings provide Slewinfinite® solutions for medium- to heavy-duty applications.

Design features

The internal configuration consists of a rectangular cross section with deep groove gothic arch raceways and maximum ball complement. This results in a four-point contact design that provides exceptional moment, thrust, and radial load capacities.

The HS and RK series share the same pinion, gear, and race core hardness. However, the HS slewing ring features reduced clearance and rectangular sections that provide additional capacity, greater stiffness, and less movement than the RK series. HS slewing ring bearings range in size from 20
