HS Series slewing ring bearings are similar in size to the RK Series, but have rectangular cross sections, which allows for alternate hole patterns as well as improved stiffness and more capacity. They are available in sizes from 20 ¨ C 47 inches OD (500 ¨ C 1200 mm) with a standard cross section.
The internal configuration consists of deep groove gothic arch raceways and maximum ball complement. This results in a four-point contact design which provides exceptional moment, thrust, and radial load capacities. Integral seals are provided to assist in the exclusion of contaminants.
Geared rings have tapped holes, while non-geared rings have through holes. HS Series bearings are available in internal geared, external geared, and non-geared configurations. The gears are Involute Stub designs with 20 deg pressure angles, manufactured to AGMA Class Q5 and. 015 to. 025 inches allowance for backlash.
All models feature two fittings for lubrication, spaced 180 degrees apart. On non-geared and internal geared models, the fittings are located on the outer diameter (Do). On the external geared models, the fittings are located on the inner diameter (di).
HS Series bearings have been used successfully in a variety of medium to heavy duty applications including:
