Space-saving slewing ring bearings

02 June 2011

The ability to deliver exceptional load and thrust with significant space savings makes the Kaydon HS Series slewing ring bearings, from R A Rodriguez, ideal for a wide range of medium to heavy duty applications. Typically they will be used in cranes, aerial lifts, digger derricks, chute swivels and industrial turntables. HS Series slewing ring bearings are designed with a rectangular cross-section, four point contact, gothic arch raceways and maximum ball complement.

This combination of features produces higher thrust and load capacities which enable the bearings to accommodate moment loads of up to 139,900 ft/lbs (190KNm). The HS Series also provides greater stiffness than comparable bearings thanks to its lower internal diametrical clearance.

Outside diameters range from 20 to 47 inches (500 to 1200mm). Configurations include internal geared, external geared and non-geared. The gears are involute stub designs with 20° pressure angles.
All HS models feature two fittings for lubrication and integral seals for protection against contamination. Geared races have tapped holes and non-geared races, through holes. 

The most popular HS Series sizes and types are held in stock or are available on short lead time.
