Race-Oriented 3Racing 48P 24T Pinion Engineering

The 3Racing 48P 24T pinion is produced with tight tolerances to support predictable backlash and repeatable gear mesh required in competitive environments. Using 7075 aluminium delivers a high strength base while the hard coating reduces surface wear on the tooth flanks under sustained loads.

Performance Notes for Tuners

  • Material Selection: 7075 alloy provides superior fatigue strength compared to common aluminium grades, useful in high rpm setups.
  • Surface Treatment: The hard coat increases abrasion resistance, extending service intervals between inspections.
  • Tooth Count and Drive Response: 24 teeth offer a practical compromise between acceleration and top speed for many 48 pitch spur pairings.
  • Application Advice: Best paired with a correctly profiled 48 pitch spur and verified mesh to avoid premature wear.

What inspection steps do you recommend after a race meeting?

Check for chipping, scoring and any deformation on tooth edges, verify set screw security, and confirm the motor shaft runout is within tolerance to avoid uneven wear.

Any guidance on torque loads for brushless motors?

Match gearing to motor Kv and battery voltage to keep torque within expected limits; excessive torque spikes from mismatched gear ratios accelerate wear even on coated surfaces.

Recommended setup checks before competition?

Confirm pitch match, verify backlash with a dial indicator if available, ensure accurate motor alignment and use thread locker on steel fasteners where needed.
