Tamiya TRF 501X Performance Bearing Pack BS-501X/V1 by 3Racing  [BS-501X/V1]

Aftermarket bearings for TRF 501X maintenance

This ball bearing set is offered as a maintenance and upgrade option for the Tamiya TRF 501X chassis, intended for rotating points such as wheel hubs, gearbox shafts and other locations that use sealed bearings to cut friction and contamination ingress.

The content below outlines compatibility reminders, simple installation guidance and how bearings fit into tuning. Good bearings contribute to drivetrain efficiency, clearer steering feedback under load and lower wear on mating parts; renewing them restores consistent behaviour.

Fitting notes: pull old bearings without marring mating surfaces, use a press or suitable driver to seat new bearings squarely, and verify free rotation before final reassembly. Secure adjacent fasteners with the correct torque and thread-lock per chassis documentation.

For hobbyists who run or service a TRF 501X, replacing sealed bearings is a low-effort maintenance task that supports reliable performance and reduces the chance of secondary gearbox damage.
