Precision 28T Hard-Coated Pulley

The Arrowmax AM-MRX5-H2201E is an aftermarket belt pulley intended for the Mugen MRX5 chassis, CNC machined from 7075 T6 aluminium and finished with a hard coating to improve wear resistance while maintaining low mass. The 28-tooth profile corresponds to MRX5 belt drive layouts and accurate machining promotes concentricity for improved belt tracking on the track.

Side apertures in the pulley body help expel debris created by belt friction, reducing the chance of buildup that can upset belt alignment. As a light alloy upgrade, this pulley is aimed at delivering repeatable belt engagement and longer service life than standard stamped components.

Fitting notes: confirm the pulley seats flush on the chosen shaft and set belt tension to the MRX5 recommended values to prevent premature wear. Regular inspection of the bore and side holes for trapped grit will support consistent operation.

Compatibility Notes

Engineered to be compatible with Mugen MRX5 chassis belt drive systems.

Does this pulley require a specific belt type?

Use belts that match the MRX5 tooth profile and width; when belt spec and shaft diameter match, the pulley is compatible with standard MRX5 belts.

Is the hard coating the same as anodising?

The pulley has a hard-coated surface treatment to improve wear resistance; check the product literature for exact coating details but expect improved surface durability over untreated alloys.

What routine checks should I perform after installation?

After fitting, ensure the pulley is flush on the shaft, verify belt tension to MRX5 guidance, and inspect the bore and side holes periodically to remove grit for consistent belt tracking.
