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

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

These 9mm aluminium ball race rollers are an aftermarket spare made by 3Racing for Tamiya Mini 4WD vehicles. The ringless ball race profile and anodised aluminium body are the key attributes for compatibility and longevity. The pink anodise denotes this colour variant for visual matching.

Compatibility details: intended for standard 9mm roller housings and common shaft arrangements used on 1/32 Mini 4WD chassis. Confirm shaft diameter and spacer configuration on MA, MS, AR, FM-A, VS, and Super-II style chassis prior to fitment; the component is intended as a direct replacement or cosmetic upgrade rather than a drivetrain modification.

Fitting pointers: verify mounting orientation and, if needed, apply a light lubricant to the bearing interface. Check for runout and secure threaded fixings to the torque you normally use for aluminium rollers to reduce the chance of loosening during running.

Maintenance notes: clean with a lint-free cloth and a mild solvent suitable for anodised aluminium if grease or dust accumulates. Do not use abrasive cleaners that may damage the finish. Retain original spacers when removing rollers to preserve alignment.

Collector guidance: the coloured anodise and ringless construction are simple to catalogue. Log any surface defects or anodising variations when sourcing spares for display or resale to keep provenance clear.
