Slew Ring Bearings

Ball bearing slewing rings of the MT Series with diameters up to 12.205 inches (310 mm) with a maximum load capacity of 185,500 lb. Offering superior moment, thrust, and radial load capacities, the MT Series is the most reliable and long-lasting slewing ring bearing option for your application.

Features/Benefits of Ball Bearing Slewing Rings

• Intermittent Rotation Under Heavy Loads: Slewing bearings handle large radial, axial, and moment loads of up to 185,000 lb with precision.
• Inner and Outer Ring Design: Consists of an inner and outer steel ring, typically face-mounted with bolt hole patterns for easy installation.
• MT Series Features: Provides economical solutions for diameters up to 12.205 inches (310 mm) with a rectangular cross-section and no gear teeth. 
• High Load Capacity: Designed for superior moment, thrust, and radial load capacities with deep groove raceways and large seals for increased performance and contamination protection.

With decades of expertise in self-lubricating bearings, PBC Linear launches our new slewing ring bearings that are maintenance-free, easy to install, and feature replaceable sliding elements in place of traditional ball bearings. Designed for high loads and rigidity, they incorporate self-lubricating plastic sliding pads within anodized aluminum inner and outer rings. 

Thanks to their grease-free design, these slew ring bearings are suitable for a variety of environments, from clean rooms to highly contaminated workspaces.

Features/Benefits of Self- Lubricating Slewing Rings

• Maintenance-Free Operation: All slewing ring bearings are completely self-lubricating, eliminating the need for grease and reducing maintenance.
• Easy Installation: Designed with replaceable sliding elements, allowing for quick and simple assembly.
• High Load Capacity & Rigidity: Engineered to withstand high loads up to 31,000 N while maintaining rigidity, making them ideal for demanding applications.
• Lightweight & Cost-Effective Options: The P02 series offers a 30% lighter, low-cost solution with plastic screws for easy handling and installation.
• Versatile Material Choices: Available with stainless steel rings and sliding pads in FDA-grade, high-temperature, and ESD-compliant materials to suit various environments and regulatory needs.
• Wide Operating Range: Designed to perform reliably in temperatures from -40°C to 120°C (248°F), making them suitable for diverse conditions.
