Kaydon HT Series Replacement Slewing Ring Bearings

Introduction

HT Series slewing ring bearings are larger versions of the HS Series, with increased ball diameter and cross-sectional area providing substantially more capacity. They range in size from 36 – 66 inches OD (900 – 1700 mm) with a standard cross section.

Design Features

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. HT Series bearings are available in internal geared, external geared, and nongeared configurations. The gears are Involute Stub designs with 20° 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 ).

Applications

HT Series bearings have been used successfully in a variety of medium to heavy duty applications including:

❚ Cranes ❚ Aerial lifts ❚ Digger derricks ❚ Chute swivels ❚ Lift truck rotators ❚ Industrial turntable
