PBC Linear - Slewing Ring Bearing
PBC Linear provides a robust selection of Slewing Bearings tailored to meet the needs of diverse industrial applications. These bearings, available with diameters from 80 mm to 310 mm, include traditional steel ball bearing models known for maximum load capacity, and polymer-lined variants offering maintenance-free operation. The steel ball bearings can sustain high moment, thrust, and radial loads, making them suitable for high-load scenarios. Meanwhile, the self-lubricating slewing rings incorporate sliding elements within anodized aluminum rings, ensuring a grease-free, maintenance-free experience, suitable for environments ranging from clean rooms to heavily contaminated spaces. Their applications extend across solar panels, medical devices, robotics, radar systems, and satellite antennas, providing reliable performance in diverse conditions.
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.
