10d Pinion M50 Nylon

Precise transmission from the motor: 10-tooth M50 nylon pinion from Scaleauto

The 10d. M50 Nylon Pinion SC-1010 from Scaleauto is a transmission component designed for those who pay attention to every detail of their slot car's drivetrain. Made from high-durability nylon, it combines lightness, wear resistance, and a smooth engagement that protects both the pinion and the crown gear it works with.

Main features

• 10 teeth with module 50, a widely used standard in competitive slot racing and tuning.
• Material: high-durability nylon, which absorbs vibrations and reduces transmission noise compared to metal options.
• Designed for standard 2 mm axle, the most common in slot motors.
• Pack of 4 units, ideal for having spare parts on hand or equipping multiple cars at once.

Function and performance

The pinion is the link that transmits power from the motor to the crown gear and, from there, to the rear axle. A poor choice—whether by tooth count or material—can result in loss of torque, overheating, or premature wear. The high-durability nylon of this SC-1010 offers balanced performance: it withstands long sessions without deforming and maintains clean engagement even with light lubricants.

With 10 teeth and module 50, this pinion defines a specific gear ratio depending on the crown gear it is paired with. The higher the tooth count of the crown gear relative to the pinion, the more torque is gained and the top speed is limited; reducing the difference increases maximum speed. It is one of the quickest and most economical adjustments to adapt the car to the type of track.

Compatibility and installation

This pinion fits any motor with a 2 mm axle and pairs with crown gears of module 50. If you are working with crown gears of a different module, the engagement will not be correct, so always check that both parts share the same module before installation.

The fit on the axle should be firm but not forced; if the pinion is loose, the transmission will lose efficiency and wear will accelerate. Scaleauto recommends properly aligning the pinion and crown gear to avoid lateral rubbing that could degrade both parts.

Ideal for…

• Club racers looking to fine-tune the gear ratio according to the circuit.
• Tuners who want to have a stock of spare pinions.
• Cars with a 2 mm axle motor where nylon is preferred over metal for its lower noise and smooth operation.

Frequently asked questions

How many units are included in the SC-1010 pack?

The pack includes 4 units of 10-tooth M50 Nylon pinion.

Which motors is this pinion compatible with?

With any motor that has a standard 2 mm diameter axle, which is the most common in slot motors.

What module should the crown gears have for correct engagement?

The crown gears should also be of module 50. Combining different modules results in incorrect engagement and premature wear on both parts.

Is nylon better than metal for this type of pinion?

It depends on the use. Nylon absorbs vibrations better and generates less noise, making it a balanced option for recreational and club use. Metal pinions can offer greater dimensional precision in high-level competitive applications but require more careful alignment.

Does it need lubrication?

A very small amount of specific slot transmission lubricant applied to the teeth improves lifespan and smooth operation. Avoid excess, as leftover lubricant can contaminate tyres or track.

The Scaleauto SC-1010 is a 10-tooth module 50 nylon pinion gear designed for standard 2 mm motor axles, supplied in a pack of 4 units. A reliable and lightweight transmission component for slot car preparation and club racing, compatible with any module 50 crown gear.
