Hitachi 608-VVM — double‑sealed 608-size ball bearing (8 x 22 x 7 mm) engineered for motor/armature and gearbox locations; hardened steel construction with VV dust seals and factory lubrication for long running life and quiet operation.

Perfect as a one-off replacement to stop grinding noises, reduce vibration, and return a single tool to service without having to replace larger assemblies.

Commonly listed as part number 608‑VVM on Hitachi parts diagrams — fits models such as the G10SS disc/grinder and the S18SB 7" disc sander (check your parts list for this exact part number to confirm fit).

This is a genuine Hitachi-bearing supplied as a single unit for straightforward swap‑in repair — ideal when you only need one replacement and are working from a parts diagram.

Sold individually for do-it-yourself repairs and maintenance; a compact, reliable option when sourcing power tool parts for a single-tool fix.
