Space-Saving HS Series Slewing Ring Bearings Now Available from Stock


MUSKEGON, MICH... Kaydon Corporation Bearings Division is now stocking many models of its space-saving HS Series slewing ring bearings, which handle moment loads of up to 139,900 ft-lbs. This is about twice the capacity of the popular Kaydon RK Series bearings, in the same envelope.

The ability to deliver exceptional load and thrust with significant space savings makes Kaydon HS Series bearings ideal for a wide range of medium-duty to heavy-duty applications, such as cranes, aerial lifts, digger derricks, chute swivels, lift truck rotators, and industrial turntables.

HS Series slewing ring bearings are efficiently designed for four-point contact, with a rectangular cross-section, deep groove gothic arch raceways and maximum ball complement. This produces higher thrust and load capacities than the Kaydon RK Series, whose "L" cross-section saves weight while providing a flange for mounting. The HS Series has less internal diametrical clearance than the RK, and therefore greater stiffness. The two series also have several features in common: the same pinion, an identical gear and equal race core hardness.

HS Series slewing ring bearings are available in O.D.s from 20 to 47 inches (500 to 1,200 mm). Configurations include internal geared, external geared and non-geared. The gears are Involute Stub designs with 20° pressure angles, manufactured to AGMA Class Q5. All HS models feature two fittings for lubrication and integral seals to protect against contamination. Geared races have tapped holes, while non-geared races have through holes.

Details of the HS Series and the other slewing ring bearings in Kaydon's extensive range can be found at the Kaydon website, www.kaydonbearings.com/turntables.htm. Complete specifications and drawings are in Kaydon's Catalog 390, available for download at www.kaydonbearings.com/downloads.htm or from the Kaydon Bearings sales department, 231-755-3741.
