3Racing M4WD-32/LB 1/32 Mini 4WD 19mm ringless aluminum ball race rollers for Tamiya Super-II and MA/MS chassis  [M4WD-32/LB]

3Racing M4WD-32/LB light blue 19mm ringless aluminum race rollers

This set of ringless 19mm aluminum ball race rollers is offered by 3Racing for use on Tamiya Mini 4WD cars. The components are machined from anodized aluminum and fitted for ball bearings, providing a consistent rolling interface for experienced builders replacing worn rollers or matching visual themes on display models. The ringless profile reduces flange interaction with track guides; check chassis clearance on Super-II, MA, or MS layouts before finalising fit.

Installation requires standard 3mm roller posts and compatible bearings or bushings. Because these rollers are aluminium, follow normal maintenance practices: inspect for burrs after crashes, avoid over-tightening fasteners that can deform the roller body, and use a light lubricant on bearing races if reassembled with ball bearings. The light blue anodizing is cosmetic and will show wear over time depending on usage and handling.

Collectors and spares-oriented hobbyists will find these rollers useful for colour-matching and replacing damaged originals. They are not a chassis performance kit; treat them as service parts and visual upgrades for 1/32 Mini 4WD runners built on performance chassis types.
