Function and performance

The pinion is one of the most requested elements of the transmission system in a slot car: it transmits the torque from the motor to the crown gear and directly influences the final gear ratio. A nylon pinion like this offers quieter operation than metal ones and better absorbs small alignment irregularities between the motor and crown, which can extend the lifespan of the assembly.

The 0.5 mm module is the most widely used standard in 1/32 scale, ensuring compatibility with a wide variety of crown gears on the market that respect the same module. Combine it with the appropriate crown to adjust the gear ratio according to the type of track and the characteristics of the motor you are using.

Mounting and preparation

Mounting is straightforward: the pinion is press-fitted directly onto the 2 mm axle. It is advisable to ensure that the axle is clean and free of burrs before mounting to ensure a good fit and avoid play. If you use axle adhesive, apply it sparingly to avoid hindering future replacements.

The brown dye allows for quick visual identification of the tooth count without needing to count the teeth each time, which is very useful when working with various pinion sizes on the bench.

Ideal for…

This pinion is aimed at tuners and enthusiasts working with 2 mm axle motors who want to adjust the transmission of their slot cars. Including 4 units makes it particularly practical for those preparing several cars with the same configuration or wanting to have spares on hand during a club racing day.

Frequently asked questions

What type of crown gears is this pinion compatible with?

With a 0.5 mm module, it is compatible with any crown that shares the same module. Always check the module of the crown before combining them to ensure correct meshing.

Is it necessary to use adhesive to secure the pinion to the axle?

The pinion is designed for press-fit, so in many cases, adhesive is not necessary. If the fit on your specific axle is somewhat loose, you can apply a minimal amount of axle adhesive, but be careful to allow for future replacement.

Does nylon hold up well in competition?

Nylon is a common material in slot pinions due to its light weight, quiet operation, and ability to absorb small misalignments. For recreational and club use, it is a very reliable option. In high-level competition, some tuners prefer metal pinions for greater hardness, but nylon remains a valid and widely used option.

Why are they dyed brown?

The brown dye serves as a visual reference for quickly identifying the tooth count (13 teeth) without needing to count. It is a common practice among slot spare parts manufacturers to facilitate organisation on the workbench.

Can I use this pinion with any 2 mm axle motor?

Yes, as long as the motor has a 2 mm diameter output shaft. Check your motor specifications before purchasing the pinion.

The Mitoos CXM213 is a 13-tooth nylon pinion gear for slot car preparation, featuring a 0.5 mm module, 7.5 mm outer diameter, 5 mm length, and press-fit mounting on a 2 mm axle. Sold in a pack of 4 units, it is ideal for 1/32 scale slot car builders and tuners looking for a quiet, reliable pinion gear compatible with standard 0.5 mm module crown gears.
