XRAY 18T Pinion for Competitive Racing

The XRAY 355718 - 18T pinion is targeted at drivers chasing reliable high speed performance on larger track layouts. Its precision teeth and chamfered profiles promote stable engagement and reduce stress on mating gears.

Engineered for Smooth Engagement

Manufactured to strict tolerances, this pinion ensures low runout and even load distribution across the tooth face. Consistent concentricity helps preserve both the pinion and spur gear life.

Designed for Higher Top Speeds

Optimised for layouts where top speed matters, the pinion helps the XB8E reach higher RPM efficiently while maintaining controllable power delivery. An M4x4 set screw is included to lock the gear to the shaft securely.

Will this pinion alter my gear ratio significantly?

The 18T tooth count is one option within a range of pinions; changing to this tooth count shifts your overall ratio and top speed according to your spur gear choice and motor characteristics.

How do I check gear mesh correctly?

Set mesh by placing a thin paper between pinion and spur, adjust until slight resistance is felt, then back off slightly. Verify after running to ensure no tight spots develop.

Is replacement common after heavy use?

With normal maintenance and correct mesh, the special steel pinion should last a long time. Replace if you notice chipped teeth or excessive wear to avoid damage to the spur.

Any tips for installing the M4x4 set screw?

Ensure the pinion sits square on the motor shaft, lightly secure the set screw, rotate to check for binding, then apply final torque. Use thread locker if you expect vibration to loosen fasteners.
