M4WD-35/PK precision dual rollers for Tamiya Mini 4WD applications

High-precision dual rollers supplied as spares for Tamiya Mini 4WD chassis. CNC-machined aluminium components finished in pink, sized for 16-17mm mounting positions, intended as a direct metal replacement for standard roller fittings. The text focuses on material specification and fitment guidance without making performance assertions.

Engineering notes: these rollers match common Mini 4WD mounting geometries and are suitable when a matched metal pair is required to replace worn polymer rollers or adjust lateral spacing. Verify shaft diameter, spacer stack height and clearance envelope on the target chassis prior to assembly to ensure correct alignment.

Technical materials guidance

  • CNC-machined aluminium offers uniform hardness and dimensional repeatability compared with moulded rollers.
  • Anodised pink finish is cosmetic; surface treatment may modify contact friction versus untreated aluminium.
  • Install using bearings or bushings specified for the chassis to preserve rotational accuracy and reduce side play.

Which chassis patterns are these rollers suitable for?

They are compatible with common Mini 4WD mounting patterns including many MA and AR configurations, subject to shaft diameter and spacer geometry checks prior to fitting.

Recommended bearing and shaft pairing?

Use Mini 4WD standard bearings or factory-specified bushings that match the inner bore; ensure shaft tolerance is within the chassis specification to minimise wobble.

How does the anodised finish affect contact properties?

Anodising adds a thin surface layer that can change micro-slip behaviour compared with bare aluminium or plastic; evaluate in your setup if precise slip characteristics matter for your build.

Installation tolerances to check before fitting?

Verify inner bore alignment, shaft runout and spacer stack height so rollers run parallel to the guide rails and maintain adequate clearance from the track and bodywork.
