Technical Pinion Overview

The 3Racing 48 Pitch Pinion Gear 46T is CNC machined from 7075 aluminium to maintain tight concentricity and tooth geometry under load. This construction reduces deflection and supports consistent gear engagement across high torque scenarios.

Material and Surface Treatment

7075 aluminium offers high yield strength and favourable stiffness for pinion applications, while the hard coating provides a thin wear-resistant layer to protect tooth flanks and delay fatigue initiation during repeated starts and stops.

Application Notes and Fitment

Intended for 48 pitch, 1/10 scale gearsets, the 46T pinion is compatible with standard spur gears when shaft diameter and spline match. For high RPM brushless systems confirm motor mounting and mesh adjustment procedures to preserve tooth profiles.

Expect tight concentric runout and consistent tooth spacing from the CNC process. These tolerances help maintain repeatable mesh and reduce vibration under load.
The coating reduces abrasive wear and slows surface fatigue. It prolongs service life compared with untreated aluminium, though inspection after aggressive use is still advised.
Ensure precise motor alignment, set minimal consistent backlash, and verify cooling for motor and ESC. Regularly inspect tooth profiles and replace the pinion if any deformation or severe wear is detected.
