Engineering Focused Hard Steel Motor Pinion

The GPM MTG4825T Hard Steel Motor Gear is engineered to provide consistent gear engagement for serious hobbyists. The 48 pitch, 25 tooth configuration and hardened steel material deliver a balance of strength and accurate tooth profile. The 3.175mm bore and 0.5mm tooth spacing are manufactured to tight tolerances to ensure reliable fit on common motor shafts and predictable drivetrain behavior.

Technical Highlights

  • Hardened steel construction for improved wear resistance under load
  • 48 pitch, 25 teeth for repeatable gear meshing and minimal play
  • 3.175mm bore to suit standard motor shaft dimensions
  • 0.5mm tooth pitch maintained for precise engagement
  • Designed as a direct replacement for 48 pitch pinion upgrades

What tolerances should I expect from this pinion?

Expect consistent bore and tooth spacing suitable for standard 48 pitch systems. Verify mesh and shaft fit during assembly to account for chassis and motor mount variances.

Is hardened steel preferable to softer materials?

Hardened steel increases wear life under repeated loading, though it may transfer more load to mating components. Balance material choice with the overall drivetrain setup.

How should I inspect the gear after runs?

Check tooth faces for pitting or flat spots, confirm bore integrity, and recheck mesh after initial runs. Replace the pinion if you observe progressive wear that affects performance.
