Tamiya MA/MS Mini 4WD 19mm Ringless Roller Set - M4WD-32/LB by 3Racing  [M4WD-32/LB]

M4WD-32/LB light blue 19mm ringless aluminium rollers for Mini 4WD

The M4WD-32/LB 19mm ringless roller bodies are produced as anodised aluminium spares for Tamiya Mini 4WD platforms. The barrels are CNC-machined and sized to accept ball bearings, offering a consistent rolling interface for modelers replacing worn rollers or matching paint schemes on display cars. Because these are ringless, the flange interaction with guide rails is reduced; always confirm clearance on MA, MS or Super-II mounts before final assembly.

Installation requires standard 3mm roller posts and compatible bearings or sleeves. As aluminium parts, check for deformation after impacts, avoid overtightening which can crush the roller walls, and apply light oil to bearing races if you use ball bearings. The light blue anodising is decorative and will wear depending on how the car is used and stored.

These rollers are intended as service replacements and cosmetic upgrades rather than performance conversion kits, making them suitable for collectors and maintenance-minded hobbyists working with 1/32 Mini 4WD chassis types.
