Racing grade bearings for Tamiya TRF 501X installations

The 3RACING BS-501X/V1 Ball Bearing Set is intended as a performance-focused replacement for the TRF 501X factory bushings. This set reduces internal resistance in rotating assemblies, improving throttle response and consistency under load.

Design and on-car benefits

Precision bearings lower mechanical losses at axles and gear interfaces, cutting heat and wear. The BS-501X/V1 is dimensioned to match TRF 501X interfaces, enabling predictable setup changes and easier tuning for competitive running.

Installation protocol and maintenance

Use a proper bearing press or matched socket to seat bearings without distorting the outer race. Verify axial and radial clearance after fitting, then apply a light race-specific oil. Monitor bearings for lubricant degradation after high-hour or wet events and service as part of routine race prep.

Confirm bearing outer diameter and housing bore run true with a caliper. Excess clearance can cause slop, while too tight a bore risks outer race stress. Aim for a light press fit with no visible gaps.
Select a thin, stable synthetic oil for high RPM sections and a light grease for slower loaded points. Maintain a consistent lubrication schedule to preserve repeatable performance.
Spin each bearing by hand to detect roughness, check for axial play, and inspect seals for damage. Replace any bearing showing noise or looseness to prevent drivetrain issues during a race.
