Precision double roller assembly M4WD-35/GO

The M4WD-35/GO double aluminium rollers are a compact upgrade for Mini 4WD cars using Tamiya-style mounts, engineered as a metal replacement where increased roller rigidity is required. Machined aluminium bodies are supplied in a golden anodised finish to improve surface hardness and wear characteristics compared with typical plastic rollers.

Intended for chassis accepting 16-17mm outer roller diameters, this component functions as a direct mechanical replacement. Prior to installation, verify shaft diameter and lateral clearance to ensure correct bearing or bushing selection. Inspect each roller for machining finish and deburr if necessary to avoid premature wear on rails or bearings.

What tolerance should I expect for outer diameter?

The specified 16-17mm range reflects the outer diameter; expect typical CNC machining tolerances and confirm with calliper measurement before mounting to avoid clearance issues.

Do I need bearings or bushes for installation?

Bearings or bushes depend on your chassis and shaft dimensions. This product is supplied as aluminium rollers only; plan for appropriate bearing/bushing selection to match shaft tolerance and intended load.

How does anodising affect sliding contact?

Anodising increases surface hardness and corrosion resistance but does not change bulk modulus. Monitor contact points for abrasive wear and consider surface conditioning if rail material is softer.

Recommended inspection after first fit?

After initial fitting, run the car at low speed and inspect rollers and rails for abnormal wear, verify free rotation under load, and retorque fasteners to spec.

Best practice for long term durability?

Keep rollers clean, avoid metal-to-metal grinding on rails, and replace rollers showing loss of anodised coating or deformation to maintain consistent handling.
