Print-in-place bearing maker
Roller bearings that print already assembled.
About the print-in-place bearing maker
A roller bearing that prints as one piece: the rollers are wider in the middle, so the two rings trap them. Good for turntables, spools and light mechanisms.
- Raise the gap if it prints fused, lower it if it rattles.
- Break it free by twisting, then add a drop of oil.
- For real loads and speed, use a steel bearing.
