70 mm Slew Bearing

thingiverse

This is a Simplified Slew Bearing That is Easier to Print Due to Its Square Race That Reduces Ball Contact to 4 Points. Its Designed for 6 mm Diameter Balls Like Airsoft BBs, But I Suppose It Would Be Possible to Print Some 6 mm Rolls. Diameter: 70 mm Thickness: 8 mm Inner Diameter: 10 mm Hardware Holes: 4.25 mm Diam. Ball Bearing Race 6 mm A Nice Feature of This Design Is That Because the Races Are Flat, It's Possible to Make a Loose Bearing More Snug Simply by Sanding the Inner Faces of the Two Halves a Little, Thereby Reducing the Size of the Square Race. Background: I Designed This Due to a Need to Relieve Non-Axial Stress on a Servo in an Motorized Steering Caster Project (See Picture). 9/25/18: I Added .STLs for 3.5 mm Spacer Disks That Can Be Useful to Leave a Gap for the Screw Heads.
