The HS Series slewing ring bearings offer high load and thrust capacity for their size and are featured in a new data sheet from Kaydon Bearings Division. Outside diameters range from 20 to 47 in. (500 to 1,200 mm). Most HS sizes are available from stock and forgings are stocked for the rest.
HS Series bearings provide four-point contact in deep groove gothic arch raceways. With about twice the load capacity of Kaydon RK Series bearings (up to 139,900 ft-lbs.) in the same envelope, they are ideal for medium-duty to heavy-duty applications such as cranes, aerial lifts, digger derricks, chute swivels, lift truck rotators, and industrial turntables. A rectangular cross-section gives the HS Series even greater stiffness than the lighter RK Series, which reduces distortion and allows lower internal diametral clearance. Kaydon HS bearings are available with internal gearing, external gearing or no gearing. Standard features include two fittings for lubrication and integral seals to protect against contamination.
