3Racing Tamiya Mini 4WD 9mm Ringless Aluminium Ball Rollers M4WD-29/PK - Chassis Option  [M4WD-29/PK]

3Racing M4WD-29/PK 9mm ringless aluminium rollers - pink option

These 9mm aluminium ball race rollers are an aftermarket spare part from 3Racing made for Tamiya Mini 4WD models. The ringless bearing layout and aluminium body define compatibility and expected longevity. The pink anodised finish helps identify this variant for visual styling or inventory.

Compatibility guidance: intended for standard 9mm roller housings and the shaft arrangements commonly seen on 1/32 Mini 4WD chassis. Confirm post diameter and spacer stack on MA, MS, AR, FM-A, VS, and Super-II platforms before fitting; the component is intended as a direct replacement and cosmetic upgrade rather than a transmission modification.

Fitting advice: ensure correct orientation when mounting and apply minimal lubricant to the bearing race if your setup requires it. Check for any runout and secure threaded fittings to familiar torque settings for aluminium rollers to avoid loosening during running.

Maintenance recommendations: clean with a lint-free cloth and a mild solvent that will not harm anodised aluminium if grease or dust collects. Steer clear of abrasive cleaners that could damage the surface. Keep original spacers during removal to maintain alignment.

For collectors: the coloured anodize and ringless profile make these straightforward to log. Note any surface blemishes or uneven anodising when sourcing spares for display or resale to preserve provenance.
