Technical overview of the 57T 64 pitch pinion

The 3RACING 64 Pitch Pinion Gear 57T is produced to tight tolerances from 7075 aluminium and receives a hard coating to lower abrasion on the contact face. The result is a pinion that retains profile accuracy under repeated loading.

Material and surface treatment details

7075 aluminium provides a high strength-to-weight ratio, and the applied hard coat reduces surface friction and micro-wear. This combination keeps backlash predictable and limits progressive tooth deformation common in softer materials.

Application and installation notes

Designed for 64 pitch systems, the 57 tooth count gives a specific ratio step for 1/10 on-road vehicles. Verify bore diameter, keying, and set-screw alignment with your motor shaft. Properly set mesh and run-in procedures will maximise service life.

What maintenance extends pinion life?

Regular mesh checks, cleaning debris from teeth, and confirming set-screw tightness after initial runs will help. Replace if tooth tips show rounding or uneven wear patterns.

How critical is mesh during initial installation?

Very. Accurate mesh prevents point loading and premature wear. Use shims or micro-adjustments to achieve uniform contact across the tooth face before securing the pinion.

Is 7075 suitable for high torque setups?

7075 offers improved strength over softer alloys, but high torque and power spikes may still favour steel pinions for ultimate durability. Evaluate based on motor power and usage patterns.
