The 140mm Slewing Bearing is the same bearing found in our Robotic Arms. Each bearing is made of a soft aluminum alloy and sports a single row of spherical bearings. These bearings give the bearing a silky smooth movement, perfect for assisting your robotic arm base, or just about any other moving joint.

The slewing bearing goes great with the Standoff Variety Pack and the Nut and Bolt Variety Pack, giving you all the hardware you need to attach the bearing to a variety of projects.

  • Diameter: 140mm
  • Height:8.5mm
  • Weight: 7.7oz
  • Mounting holes: Twelve 3mm mounting holes (also 4-32" compatible)
