To sharpen your RC car's drivetrain, the Tamiya 42368 850 sealed ball bearings provide consistent rotational performance and tighter tolerance compared with basic bushings. These sealed bearings are a practical upgrade for hobbyists who prioritise dependable operation and straightforward upkeep.
The 850 sealed bearings work well in several Tamiya locations, such as center shafts on TRF420 and TA07MS platforms and within M-chassis gear assemblies. Swapping out plastic or open metal bearings for these rubber-sealed units typically yields a more accurate fit and smoother rolling action.
The rubber seal design lets you open the seal for cleaning and relubrication, which is easier than with fixed metal shields. Using a low-friction bearing oil after cleaning helps maintain steady operation and reduces wear over repeated runs.
