Precision Alloy Pinion for Reliable Gear Mesh

The Arrowmax AM-348040 Pinion Gear serves modellers seeking precise, long-lasting performance. Machined from 7075 aluminium, the 48P 40T configuration provides dependable tooth engagement and reduced rotating weight.

Strength and Weight Considerations

Using 7075 aluminium delivers a good compromise between stiffness and lightness, helping retain tooth profile under load while keeping inertia low for snappy throttle response.

Suitable Applications

This pinion is intended for gearboxes that accept 48 pitch components and performs well on both speed-oriented layouts and technical circuits that demand consistent ratios.

What checks are recommended after fitting?

After fitting, verify set screw torque, confirm proper gear mesh using a thin shim, and run a short test at low speed to listen for unusual noise.

Can this pinion be used with different spur sizes?

Yes, as long as the spur uses a 48 pitch. Changing spur size alters final ratio so select a spur that matches your performance goals.

How often should I inspect the pinion?

Inspect teeth and set screw tightness after every few runs, or immediately after any impact, to avoid progressive damage to the gearset.
