30/11/7/8 Nylon Roller with 608 ZZ Ball Bearing

This small heavy-duty roller from Germany has a high-grade thermoplastic polyamide bonded directly to a 608ZZ sealed for life ball bearing. The hard (54 Shore D) nylon tread can carry very high loads especially at lower speeds. It is non-marking, wear and tear resistant, with a low rolling resistance. This wheel can also operate effectively at high and low temperatures and is resistant to many oils and greases.
