Product Description
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″ to 47″ (500 mm to 1,200 mm) OD with a standard cross section. Configurations include non-geared and internal geared (with fittings on the outer diameter), and external geared (fittings on the inner diameter). The gears are Involute Stub designs with 20° pressure angles, manufactured to AGMA Class Q5 and .015″ to .025″ allowance for backlash.
HS slewing ring bearings feature two fittings for lubrication, spaced 180° apart. Geared races have tapped holes, while non-geared races have through holes. All have integral seals designed to protect against contamination.
