Precise Positioning Kaydon Slewing Bearing , Heavy Duty Bearing With Consistent Repeatability

Kaydon KH Series Slewing Ring Bearings precise positioning with consistent repeatability

 

KH series heavy duty slewing rings are designed to provide precise positioning with consistent repeatability, in applications where rotation is constant, intermittent or oscillating. They are the ideal bearing for advanced rotary index tables or any design where the bearing will interface with other precision mechanical components.

 

Kaydons KH series precision slewing ring bearings are designed to provide precise positioning with consistent repeatability, in applications where rotation is constant, intermittent or oscillating. KH slewing rings offer Slewinfinite® solutions for advanced rotary index tables or any design where the bearing will mesh with other precision mechanical components.

Design features

The internal configuration is a deep groove gothic arch raceway, which provides four points of contact with the balls, enabling it to carry radial, moment, and thrust loads individually or simultaneously. The use of internal diametral preload provides for greater stiffness, which combined with tightly controlled radial and axial runouts, delivers accurate repeatability. The axial runouts are 0.001 inches TIR and the radial runouts for locating diameters are 0.002 inches TIR. A separator is used to maintain consistent ball spacing interval, keep friction to a minimum, and minimize noise. Integral face riding seals are provided to assist in the exclusion of contaminants.

KH series precision bearings are offered in nongeared and externally geared configurations. The gears have full depth involute teeth and are manufactured to an AGMA Class Q8 quality, allowing for decreased backlash, more accurate positioning, and less noise while operating.

 

Availability

KH series slewing rings have a rectangular cross-section, range in size from 16–37 inches OD (400–950 mm), and are generally available from stock.

 

Applications

KH series slewing ring bearings have been used successfully in applications demanding higher precision, including:

• Precision rotary index tables

• Radar antennas

• Satellite antennas

• Robots

• Medical systems and medical devices

• Machine tool tables

• Any design where the KH bearing will interface with other precision components
