Slewing Bearings, or Slew Ring Bearings, are designed for applications needing intermittent rotation while managing heavy radial, axial, and moment loads. Each bearing features inner and outer rings with bolt hole patterns for secure mounting. PBC Linear® offers two main types: ball bearing slewing bearings in steel, stainless steel, and polymer, plus plain linear bearings with anodized aluminum rings that slide on self-lubricating polymer pads.
Different variants offer electrostatic compliance, FDA compliance, high temperature or all-weather durability. We offer a range of Slew Ring Bearings with outer diameters from 80 mm to 310 mm, suitable for applications like solar tracking, medical devices, robotics, radar systems, and satellite antennas. All bearings are in stock for immediate shipment from our US manufacturing facility.
