Self-Lubricating Slew Ring Bearings

Maintenance-Free Rotary Motion for High Loads


Gliding surface polymer slewing ring bearings, maintenance-free and designed for easy installation with replaceable sliding elements. Built to withstand very high loads while providing high rigidity, these bearings feature anodized aluminum rings and self-lubricating, high-performance polymer sliding pads instead of traditional ball bearings. This product is the result of years of PBC Linear expertise in self-lubricating bearings, making it ideal for a wide range of applications, from clean rooms to environments with contaminants, thanks to its grease-free, self-lubricating design. With a maximum temperature limit of 248°F (120°C) and a lower application temperature of -40°C, these bearings ensure reliable performance across diverse operating conditions.
