Eight-Point Contact Ball Slewing Ring Bearings

What Are Eight Point Contact Ball Slewing Bearings?
Eight point contact ball slewing ring bearings use a double-row ball configuration, forming eight contact points between balls and raceways. This design allows the bearing to handle complex combined loads — axial, radial, and tilting moments — while ensuring smooth and precise rotation under heavy-duty conditions.

Product Configurations
We offer versatile structural options to suit a wide range of system designs:

Internal Gear: Ideal for compact enclosed gear drives.
External Gear: Enables efficient torque transfer and easy integration.
Without Gear: Preferred in friction-drive systems or where custom gearing is used.

Compatible With Leading Global Brands
All models are designed to be dimensionally and functionally interchangeable with the following brands, helping reduce lead times and simplify sourcing:

KAYDON
ROTEK
ROTHEERDE

Applications
Engineered for high-performance systems requiring precise motion control and durability, these bearings are widely used in:

Rotary indexing tables
Robotic arms and manipulators
Military and aerospace radar systems
Wind turbines and offshore machinery
Medical imaging and diagnostic equipment

Key Advantages

Engineered with precision and tested under stringent quality standards

Selection Guidelines
To maximize performance and longevity, consider the following when selecting a slewing bearing:

Expected load types and directions (axial, radial, tilting moment)
Mounting space constraints and gear type compatibility
Environmental conditions such as humidity, dust, or temperature
Whether interchangeability with existing components is required
