High-Quality Pinion by Arrowmax

The Arrowmax AM-348028 Pinion Gear delivers a compact, hardwearing option for racers and tuners. Machined from 7075 aluminium, it aims to keep gear faces true under sustained loads.

Material Advantages in Practice

7075 aluminium resists wear and keeps safety margins on tooth profiles, which helps maintain consistent engagement and prevents early rounding of teeth in active use.

Compatibility Notes and Use Cases

The 48P 28T format suits many popular spurs and is ideal when you want a precise gear step rather than a large ratio change. It works well in both on-road competition and light off-road rigs.

What maintenance keeps this pinion running well?

Regularly inspect for burrs and clean grit from teeth, keep bearings maintained, and ensure the motor mount keeps the correct mesh under load.

Is 48P better than coarser pitches for smoothness?

Finer 48-pitch gears tend to deliver smoother engagement and quieter operation versus coarser pitches, provided the gears are properly aligned.

Any tips for installing on a standard motor shaft?

Ensure the shaft is clean, fit the grub screw in the keyway if present, and use a small amount of threadlocker on the screw if you experience slippage.
