GPM Racing 40CR Steel Motor Gear 23T (Module:0.5mm,motor Tooth Diameter:2.2mm) (MG223T/0.5M)

Product overview

The MG223T/0.5M pinion is a 23-tooth motor gear sized for a 0.5mm module and a 2.2mm motor tooth diameter, made from 40Cr steel to provide durable tooth surfaces. The pinion fits motors with a round motor hole and is secured using two 3×3 set screws to maintain axial position.

Installation: check shaft diameter and module compatibility before installation, fit the pinion so teeth mesh evenly with the spur gear, then tighten the two 3×3 set screws evenly. Perform a low-speed check to confirm correct mesh and no binding.

Performance note: as a like-for-like replacement, this pinion helps restore accurate gear mesh and resists accelerated wear compared with worn components. Confirm gear ratios and compatibility with your motor and spur gear before sustained use.

Which motor dimensions must match for fitment?

Confirm the motor accepts a 0.5mm module pinion with a 2.2mm motor tooth diameter and a round hole that can be clamped with two 3×3 set screws for secure fitment.

What is the correct installation sequence?

Slide the pinion onto the motor shaft, align mesh with the spur gear, then tighten both 3×3 set screws evenly. Recheck alignment and run at low throttle to ensure proper engagement.

How does 40Cr affect service life?

40Cr steel increases resistance to wear and helps the pinion retain accurate tooth geometry under normal operating loads, reducing the need for frequent replacement. Write Product Review Please sign in your account before you can write any review. Sign In Close
