High-wear resistance with Arrowmax 0.8M 20T

The Arrowmax AM-308020 pinion gear provides a dependable option for those refining drivetrain reliability. Constructed from 7075 hard aluminium, its 0.8 module 20-tooth profile helps preserve accurate gear engagement over long use.

Material reasons to choose 7075

7075 offers superior hardness and wear resistance compared with lower grade alloys, which helps minimise tooth deformation and maintains gear timing under sustained loads. This makes it a sound choice for persistent running or competitive use.

Practical applications

Ideal for model builders adjusting gear ratios or replacing worn pinions, this Arrowmax part suits a variety of 1/10 scale drivetrains where longevity and consistent mesh are priorities.

How do I confirm the module and tooth count match my build?

Verify your spur gear's module is 0.8 and that 20 teeth gives the ratio you want; if modules differ, gears will not mesh properly.

Is there a recommended grub screw torque?

Tighten the grub screw just enough to prevent slippage without crushing the shaft; light threadlocker can be used sparingly for added security.

Should I replace a pinion after a heavy impact?

Inspect teeth for chips or burrs; any visible damage can accelerate wear on the spur and should prompt replacement.

What lubrication works best for metal pinions?

A light film of gear-specific grease on the spur can help protect teeth, but avoid heavy pastes that attract dirt and grit.
