Intro to the Tamiya 95643 19mm Aluminium Ball-Race Ringless Rollers

The Tamiya 95643 19mm Aluminium Ball-Race Ringless Rollers mark the Mini 4WD 40th Anniversary with a lightweight aluminium build and integrated 520 ball bearings for reliable rotation. These rollers are intended to reduce rotating mass and help stabilise cornering on race circuits while adding a subtle anniversary graphic to your build.

Roller construction and model fit

Finished in silver with an orange Mini 4WD 40th Anniversary logo, the ringless profile trims excess weight yet keeps structural strength for competitive use. These rollers suit standard Mini 4WD and Mini 4WD PRO models, and can be used with a range of chassis types. Some body or mounting tweaks may be needed to achieve the best clearance.

On-track benefits and handling notes

Add these rollers to improve corner speed and reduce friction from axle-to-body contact. The 520 ball bearings help deliver smoother rotation and more consistent lap times, making them a practical choice for drivers seeking handling gains without drastic chassis changes.
