Slewing Ring Bearing

Precision Rotation in a Compact Size

Cost- effective Slew Ring Bearings from PBC Linear® are offered in diameters up to 12.205 inches (310 mm). Their deep groove raceways and larger ball sizes deliver superior load-handling capabilities, offering higher moment, thrust, and radial load capacities compared to standard four-point contact slewing bearings. Both the inner and outer rings are composed of durable steel, ensuring strength and reliability in demanding applications.

Slew Ring Bearings are designed for a wide range of applications. They are commonly used in positioning and indexing tables, robotics, medical equipment, and small wind turbines, making them a versatile solution for industries that demand precision and durability. 

Performance Benefits of Ball Bearing Slewing Rings:

  • Versatile Performance: Excels in applications ranging from light to heavy loads.
  • Superior Load Handling: Deep groove raceways and maximum size balls provide higher torque, thrust, and radial load capacity compared to standard four-point contact ball bearings. 
  • High Stiffness: Offers exceptional rigidity for demanding bearing applications.
  • Cost-Effective: Delivers an excellent price/performance ratio.
  • Excellent Durability: Ensures a long service life in a variety of environments, -40°F to +140°F (-40°C to +60°C).
  • Enhanced Protection: Larger seals and non-contact dust covers on the bearing grooves effectively block contaminants.
  • Increased Load Capacity: Certain sizes feature enhanced load-bearing capabilities.
