GPM Racing 40CR Steel Motor Gear 14T (Module:0.5mm,motor Tooth Diameter:2.2mm) (MG214T/0.5M)

Product brief

The MG214T/0.5M pinion is an aftermarket 14-tooth motor gear made for motors matching the specified tooth form. Crafted from 40Cr steel, the pinion offers a hardened option for tight drivetrain installations and is intended for motors with a 2.2mm motor tooth diameter and a round bore.

Details: 14 teeth (14T), 0.5mm module, and a round motor hole. Two 3x3 set screws provide axial clamping when tightened opposite each other to minimize slippage. Always verify motor shaft and mesh compatibility before installation.

Advice: ensure correct mesh with the spur gear and tighten set screws evenly. When experimenting with gearing, proceed in small steps and monitor drivetrain load and motor temperature for safe operation.

What dimensions should I check before fitting this pinion?

Confirm the motor tooth diameter is 2.2mm, the bore is round, and that the motor accepts a 0.5mm module pinion; also check shaft diameter for set screw compatibility.

Are the supplied set screws sufficient for long-term use?

The two 3x3 set screws provide balanced clamping for typical RC use; tighten them evenly and inspect periodically. For high-vibration environments, consider threadlocker and routine checks to maintain security. Write Product Review Please sign in your account before you can write any review. Sign In Close
