Summary of benefits

The Tamiya 15393 JR Steel Bearing set is intended for Mini 4WD builders looking to upgrade drivetrain efficiency. Each 620-sized bearing receives a fluorine coating that limits friction and supports longer service intervals under racing use.

Compatibility and correct fit

These 620 bearings are compatible with the common Mini 4WD wheel and axle arrangements. They suit many chassis styles, such as MS, MA and AR, and generally install without complex modifications.

Handling and lap time effects

Installing fluorine-coated steel bearings in place of basic bushings produces smoother wheel rotation and improved stability. That leads to steadier speed on straights and firmer control through technical sections.

A short break-in of a few runs helps seating and removes any light manufacturing residue. After that they should run smoothly with minimal additional bedding in.
Yes, reduced rotational resistance helps the wheels regain speed more quickly after corners, which can improve exit times and lap consistency.
They are a common and effective early upgrade for Mini 4WD cars, offering a clear performance step up from standard bushings without major build changes.
