Tamiya 42369 - 840 Sealed Ball Bearings (2pcs) - compact drivetrain polish  [42369]

Improved rotation and maintainability

The Tamiya 42369 - 840 Sealed Ball Bearings give hobby drivers a reliable way to cut drivetrain friction. Their rubber seals help keep contaminants out while allowing routine servicing to keep spin consistent.

Perfect for pulleys and counter gear areas

These bearings are a common fit around TA07 pulley mounts and M-chassis counter gears. Fitting the sealed 840 units can restore smooth movement and reduce drag where stock bearings have worn.

Accessible seals for periodic servicing

Unlike permanently sealed metal units, the rubber-sealed design makes it possible to open, clean, and relube the bearings. They are supplied with low-friction lubrication to maintain smooth operation until you service them.
