Turntable thrust bearing for 13mm steel balls

thingiverse

Thrust bearing for 13mm steel balls requires exactly twenty balls to function properly. Originally conceived as a scrollable background mechanism on stage, it has been successfully adapted into a turntable or lazy susan setup. A feature video showcases the bearing components in action, mounted on a wooden plate and a sheet of paper: https://youtu.be/D4AIwcGMFz4 This thrust bearing consists of three essential parts: 1. Lower race 2. Cage 3. Upper race It can also be used with two lower races if needed. The upper race features a small guard to prevent it from slipping out. To load the balls, simply insert one ball into every second hole, then place on the upper race and turn 180 degrees. Load the remaining balls, followed by attaching the lower race. Both the upper and lower races boast counter-synchronized screw holes for added stability. In PLA material, this thrust bearing can easily support at least two human weights. A Fusion 360 file is included for further customization or modification.
