Kaydon KH Slewing Ring Bearings

The internal structure comprises a deep groove gothic arch raceway, ensuring four points of contact with the balls, allowing it to handle radial, moment, and thrust loads individually or simultaneously. The use of internal diametral preload enhances stiffness, combined with precise control of radial and axial runouts, ensuring accurate repeatability. Axial runouts are maintained at 0.001 inches TIR, and the radial runouts for locating diameters are at 0.002 inches TIR. To maintain consistent ball spacing, reduce friction, and minimize noise, a separator is utilized. Integral face riding seals are included to prevent contaminants from entering.

KH series precision bearings are available in non-geared and externally geared configurations. The gears feature full-depth involute teeth and are manufactured to AGMA Class Q8 quality, resulting in reduced backlash, precise positioning, and quieter operation.

Applications

KH series slewing ring bearings have proven effective in applications requiring elevated precision, such as:

• Precision rotary index tables
• Radar antennas
• Satellite antennas
• Robots
• Medical systems and medical devices
• Machine tool tables
• Any design where the KH bearing interfaces with other precision components

The features of Kaydon’s HS slewing ring bearings are as follows:

1. Deep Groove Gothic Arch Raceway: The internal configuration of KH series bearings likely includes deep groove gothic arch raceways, providing four points of contact with the balls, enabling them to handle radial, moment, and thrust loads individually or simultaneously.
2. Internal Diametral Preload: KH bearings may feature internal diametral preload, enhancing stiffness and ensuring accurate repeatability.
3. Controlled Radial and Axial Runouts: To maintain precision, KH series slewing ring bearings are likely to have tightly controlled radial and axial runouts, with axial runouts at 0.001 inches TIR and radial runouts for locating diameters at 0.002 inches TIR.
4. Separator: A separator may be incorporated in the KH bearings to maintain consistent ball spacing intervals, minimize friction, and reduce noise during operation.
5. Integral Face Riding Seals: KH series slewing ring bearings may come with integral face riding seals, assisting in the exclusion of contaminants and ensuring the bearings’ longevity and reliability.
6. Non-geared and Externally Geared Configurations: The KH series is likely available in both nongeared and externally geared configurations, providing design flexibility for various applications.
7. Full-Depth Involute Gears: If the KH bearings are available in geared versions, the gears may feature full-depth involute teeth manufactured to AGMA Class Q8 quality. This allows for decreased backlash, more accurate positioning, and quieter operation.
