Ball Roller Slew Ring Bearings

Ball Bearing Slewing Ring Bearings

Precision Rotation with Superior Load Capacity

PBC Linear's **Ball Bearing Slewing Ring Bearings** are engineered for optimal performance and cost-efficiency, accommodating diameters up to 12.205 inches (310 mm). Featuring deep groove raceways and larger ball diameters, these bearings provide **superior load-handling capabilities**, offering higher moment, thrust, and radial load capacities compared to standard four-point contact slewing bearings. The incorporation of ball bearings allows for smooth rotation and precise motion control, essential for high-performance applications.

To ensure long-lasting performance, the bearings are equipped with enhanced sealing systems—including larger seals and non-contact dust covers—that effectively protect against contaminants and retain lubrication. Both the inner and outer rings are constructed from durable steel, providing strength and reliability in demanding environments.

Ball Bearing Slewing Ring Bearings, also known as slewing bearings, turntable bearings, or slew rings, are designed for applications requiring precise rotational motion and high load capacities. They are commonly used in positioning and indexing tables, robotics, medical equipment, and small wind turbines. The MT Series is available from stock, while the KH, HS, HT, and RK Series are available for order, offering versatile solutions for industries that demand precision and durability.
