This listing is for two 5 x 10mm Teflon-sealed ball bearings intended as RC replacement parts. The Teflon seal gives improved resistance to dust and helps the lubrication remain in place, which suits compact installations in model assemblies.
Installation is compatible with components made to accept 5 x 10mm bearings, including wheel hubs, small gearboxes and other rotating assemblies. Use appropriate press-fit or retention techniques and avoid applying excessive sideways force during insertion to prevent damage.
Upgrading to sealed ball bearings can decrease rotational drag and enhance smoothness in drivetrains and steering linkages. Periodic inspection and cleaning of adjacent parts will help the seals last longer, and replacing bearings as matching pairs will keep axle performance consistent.
