Moturo Deep Groove Ball Bearing 6004-RS 42×20×12 mm

The Moturo 6004-RS deep groove ball bearing for scooters, quads, and bikes — a typical wear-and-tear bearing in drivetrains and wheel bearings. Outer dimension 42 mm, bore 20 mm, width 12 mm, rubber-sealed on one side, ready for installation.

The 6004 is a single-row deep groove ball bearing with a single-sided rubber seal (RS version). Outer ring 42 mm, inner bore 20 mm, width 12 mm — the standard geometry of the 6004 type according to DIN 625. Material according to source: metal with rubber seal.

The bearing serves as a wear part in the drivetrains of variomatics, in the wheel hubs of smaller quads, and in steering head bearings. If the old bearing runs roughly or has play, replace it with an identical one with the same model designation.

Installation takes about half an hour with a bearing puller or press tool.
