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

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

These 9mm aluminium ball race rollers are an aftermarket spare from 3Racing designed for Tamiya Mini 4WD cars. The ringless bearing form and aluminium construction are the defining features for fitment and expected service life. The pink anodised surface marks this colourway for easy identification.

Fit notes: compatible with standard 9mm roller housings and common shaft arrangements on 1/32 Mini 4WD chassis. Check post diameter and spacer clearance on MA, MS, AR, FM-A, VS, and Super-II chassis before fitting; the part is intended as a direct replacement or visual upgrade rather than a drivetrain alteration.

Installation guidance: confirm correct orientation and use a light lubricant on the bearing interface if your setup benefits from it. Inspect for axial runout and tighten threaded components to the torque levels you normally use for aluminium rollers to prevent loosening during use.

Care instructions: clean with a lint-free cloth and a mild solvent that is safe for anodised aluminium if grease or dust collects. Do not use abrasive cleaners that will damage the finish. Keep original spacers when removing rollers to maintain alignment.

Collector advice: the coloured anodise and ringless profile make these easy to catalogue. Record any marks or anodising irregularities when acquiring spares for display or resale to maintain provenance.
