Fine tune your Mini 4WD with Tamiya 94758 JR 19mm rollers

The Tamiya 94758 JR 19mm Aluminum Ball Race Roller is a useful performance part for Mini 4WD hobbyists seeking improved track behaviour. Precision aluminium construction ensures durability during frequent running. The gun metal finish reduces contact friction, helping the car maintain a cleaner line through bends and offering steadier handling.

Compatibility details and kit contents

This roller set is compatible with Mini 4WD and Mini 4WD PRO cars, making it a versatile addition to many builds. Fitted with 520 ball bearings to minimise rotational resistance, the package also contains screws, rubber rings and aluminium spacers so installation is straightforward.

How should I set roller clearance?

Set clearance so the roller does not contact the track edge while still allowing free spin; small adjustments with the aluminium spacers help dial in the gap.

Can I run these on oval and straight tracks?

They perform well on both types; the low-friction bearings and aluminium body support stable rolling at speed and through sustained corners.

Is additional lubrication required?

A light application of suitable bearing oil keeps the 520 bearings turning smoothly, but avoid heavy greases that can attract dirt and slow rotation.
