Technical Overview for 3RACING 3RAC-PG6425

The 3RACING 64 Pitch Pinion Gear 25T is engineered to deliver stable meshing characteristics under racing loads. Fabricated from 7075 aluminium and finished with a hard coating, it provides a low mass solution that preserves tooth profile integrity during repeated runs.

Material and Coating Details

  • Material: 7075 aluminium offers high tensile strength and a favourable stiffness to weight ratio for drivetrain components.
  • Coating: The hard coating increases surface hardness to slow abrasive wear while maintaining dimensional tolerances.
  • Compatibility: Engineered for 64 pitch systems requiring a 25-tooth pinion; verify spline fit and bore clearance prior to installation.

Application Notes

For racing setups, ensure precise motor mount alignment and minimal but safe backlash. The 3RACING 3RAC-PG6425 is best used where weight savings and consistent tooth engagement are priorities, and where replacement is easier than attempting in-field repair.

What torque limits are appropriate for this aluminium pinion?

While 7075 aluminium is strong, aluminium pinions have lower shear resistance than steel; use this pinion within typical electric touring car torque ranges and monitor for tooth deformation under extreme loads.

How do I set ideal mesh for racing?

Set motor position to a fine mesh with slight backlash, check full rotation under load, and use a small amount of high quality grease to inspect contact patch across the tooth face.

Is heat treatment relevant for this component?

Heat treatment is not typical for aluminium pinions; the hard coating provides surface protection while maintaining dimensional accuracy achieved during machining.
