Pinion Technical Notes

The MG219T/0.5M is a 19T pinion cut to a 0.5mm module, intended for gear trains where the motor tooth diameter is 2.2mm. Fabricated from 40Cr steel with a hardened surface finish, it aims to deliver longer service before wear becomes noticeable.

Key fitment points: the round bore accommodates standard 2.2mm motor tooth diameter interfaces and the pinion is secured by two 3x3 set screws. Always match the spur gear module and tooth count to the pinion to achieve correct mesh and prevent premature failure.

Assembly guidance: fit the pinion so the bore is flush where applicable, tighten set screws in small, alternating increments, and inspect pinion-to-spur backlash under load. Adjusting pinion size or mesh will influence torque delivery and top speed, so keep notes of each configuration change for reference.

Does the heat treatment on 40Cr require special care?

No special care is needed beyond normal checks; the surface hardening improves wear resistance but you should still monitor mesh, remove debris, and lubricate spur gear interfaces as recommended.

What spur gear size pairs well with a 19T pinion at 0.5mm module?

The best spur depends on the desired ratio; ensure the spur is cut to a 0.5mm module and has the tooth count that delivers the ratio you need, then test for smooth engagement.

How should I set backlash for maximum durability?

Aim for a small, consistent backlash that allows free rotation without excessive play; too tight causes binding and too loose increases wear, so fine-tune incrementally.
