Slew ring bearings, also known as slewing rings or turntable bearings, are rotary bearings designed to support heavy radial, axial, and moment loads while enabling intermittent rotation. Plain slew rings have a robust construction with anodized aluminum rings and self-lubricating polymer sliding pads in place of traditional ball bearings. These maintenance-free bearings feature replaceable sliding elements for easy installation, exceptional rigidity, and operation in diverse environments like clean rooms or contaminated settings without grease. With outer diameters ranging from 80 mm to 310 mm and a wide temperature range from -40°C to 120°C (248°F), they offer high load capacities and durability. Variants include electrostatic, FDA-compliant, high-temperature, and all-weather options, supporting up to 600 rpm for dynamic operations.
