Precision chrome spiral gear

The STXM1200FR/G is a single-piece chrome steel spiral gear engineered for TRAXXAS X-MAXX applications. Manufactured with a 42-tooth spiral profile from high-grade chrome steel and specified at hardness 50, the component is intended for front or rear spiral locations within the gearbox.

Compatibility is constrained to matching spiral components STXM1200F/G1 and STXM1200R/G1; it is not suitable for stock low-grade steel spur gears. Proper pairing minimises impact damage during abrupt braking and preserves consistent drivetrain engagement under high torque conditions.

What inspection steps ensure correct installation?

Verify shaft endplay, bearing fitment and tooth contact pattern with the matching spiral mate before final assembly.

How should I set mesh for long-term durability?

Set a conservative backlash, check under load, and use a compatible lubricant to reduce wear between spiral teeth.

Are there common failure modes to watch for?

Misalignment, contaminated grease and improper mating parts can accelerate tooth wear or chipping; regular inspection prevents these issues.
