For tighter rolling and less drivetrain drag, the Tamiya 42368 850 sealed ball bearings help reduce friction and improve accuracy in moving assemblies. They are a sensible choice for modelers aiming for cleaner rotation and manageable maintenance.
These sealed 850 bearings suit several Tamiya components, such as center shafts on TRF420 and TA07MS cars and gear areas on M-chassis models. Replacing generic plastic or unsealed metal bearings with rubber-sealed ones delivers a neater fit and quieter rotation.
Because the seals are rubber, they can be lifted for cleaning and relubrication, unlike permanently shielded bearings. Applying a small amount of low-friction oil after cleaning keeps the bearing turning freely for longer.
