Strong 21T 48P pinion from XRAY 385621 for steady power delivery

The XRAY 385621 steel pinion offers a practical upgrade for model builders wanting a robust 21-tooth, 48-pitch gear. Its precision-cut profile promotes even contact across the teeth, helping to stabilise gear mesh and reduce vibration during runs.

Precision cuts and chamfers for improved gear life

Careful machining and chamfered teeth lessen contact stress and slow wear. The run-in surface finish helps the part bed into your gearbox quickly so you can get back on the track with minimal setup fuss.

Ideal for routine swapouts and tougher use

Whether refreshing an older build or strengthening a touring or buggy setup, this pinion's steel construction is built to hold up under higher loads while keeping consistent gear ratios.
Remark :
Due to limited stock availability, please notice that some XRAY items may have to order from the factory and the ready time is around 4-6 weeks. Customer purchases the item is assumed to accept the waiting time which allows us to order directly from the manufacturer if the item is out of our warehouse.

Which shaft sizes work with this pinion?

Confirm your motor or idler shaft diameter before fitting; the XRAY 385621 is designed for typical 48-pitch installations but shaft fit can vary by model.

Is steel better than aluminium for pinions?

Steel offers greater wear resistance than aluminium, which can be beneficial under heavy load, though steel may be slightly heavier depending on design.

How do I check pinion mesh correctly?

Set mesh with a thin non-permanent method like paper or a mesh gauge, ensure minimal backlash and verify the pinion sits square on the shaft before tightening.

Can I use this in both on-road and off-road models?

Yes, the XRAY 385621 suits a range of 48-pitch drivetrains; ensure your vehicle's power and terrain demands match the gear's durability for optimal life.
