LMU88

LMU88 Replacement Bearing with multi-contact & multi-direction surfaces. No play in any direction and the design is scalable to suit other shaft diameters.

I have only printed it in PLA but PLA is not the best wear material. Probably best in ABS or PETG.

Internal diameter is designed size on size for an 8mm (7.95mm measured) ground rod so after shrinkage there is a slight interference hence the hollow walls for the 'give' and preload.
