40Cr hardened pinion for micro motors

The MG316T/0.5M motor gear is produced to match standard micro motor pinion specifications, providing 16 teeth with a 0.5mm module and a 3.175mm motor tooth diameter for common model geartrains.

Constructed from 40Cr steel and finished in a hardened black treatment, this pinion is described to reduce wear and maintain consistent gear mesh over extended use. The motor bore is round and the part is fixed in place using two set screws (3x3) to secure it axially on suitable shafts.

When installing, verify shaft diameter, module, and tooth count relative to your spur gear to avoid poor mesh or excessive backlash. The part is intended for replacement or to fine-tune gear engagement in RC-scale motor systems that match the stated dimensions.

Does the hardened finish improve service life?

The heat-treated black finish on the 40Cr steel helps resist surface wear, supporting longer-term mesh stability. Regular inspection of gear teeth and mesh is still recommended for high-use models.

Can I reinstall this pinion after removing it multiple times?

Yes. The round bore and two 3x3 set screws allow repeated service, though check screw threads and bore condition each time and avoid over-tightening to preserve shaft and pinion integrity.
