Uncompromising Transmission: The Pinion That Works Match by Match

The 14d. M50 Nylon Pinion SC-1014 from Scaleauto is designed for those who know that the transmission is one of the critical points of any slot car. With 14 teeth, Module 50, and made from high-durability nylon, it offers smooth, quiet engagement and wear resistance, maintaining a stable gear ratio session after session. The pack includes 4 units, providing ample spares to prepare several cars or to ensure you don't run out of stock at the least opportune moment.

Main Features

• Teeth: 14
• Module: 50 (M50)
• Material: High-durability nylon
• Axle Diameter: 2 mm (standard axle)
• Pack Contents: 4 units
• Reference: SC-1014 — Scaleauto

Function and Performance

Module 50 is one of the most widely used standards in competition and preparation slot racing. Nylon, compared to brass or conventional plastic, better absorbs micro-vibrations from the motor and reduces transmission noise, resulting in smoother operation and less wear on the crown gear. Additionally, nylon tolerates continuous high-rev work well without losing shape or precision in tooth engagement.

Compatibility and Installation

This pinion is designed for motors with a standard 2 mm axle, making it compatible with a wide variety of common motors used in slot preparation. Always check that the module of your crown gear matches the M50 of this pinion before installation: mixing different modules creates play, noise, and premature wear. The correct fit is one where the teeth mesh cleanly, with no excessive play but without pressure between them.

For installation, apply a small amount of fine cyanoacrylate glue or secure it with a nut/bolt system if your chassis allows, always verifying alignment with the crown gear before finalising the setup.

Common Mistakes to Avoid

• Combining this M50 pinion with crown gears of a different module (M48, M64…): the engagement will not be correct.
• Installing the pinion misaligned with the crown gear: causes lateral wear and loss of efficiency.
• Not checking the play between pinion and crown gear before racing: excessive or no play ruins the transmission.

Ideal for…

Preparers and enthusiasts working with 2 mm axle motors who need a reliable transmission pinion, with good tolerance to heat and continuous wear. The pack of 4 units is especially useful for those managing several cars in parallel or participating in club championships where quick replacements make a difference.

Frequently Asked Questions

Which crown gears is this pinion compatible with?

With any Module 50 (M50) crown gear. It is essential that both pieces share the same module to ensure correct engagement and avoid premature wear.

What axle diameter is it prepared for?

For the standard 2 mm axle, the most common in slot preparation motors.

Why choose nylon over brass for a pinion?

Nylon better absorbs vibrations and reduces transmission noise. Additionally, it is gentler on the crown gear, generating less wear on the pinion-crown pair over time. Brass offers greater rigidity, but in many applications, nylon proves to be more balanced for intensive use.

How many units does the pack include?

The SC-1014 pack includes 4 units.

Can I use this pinion in sidewinder and inline configurations?

Yes. The pinion itself is compatible with both configurations. What varies is the motor's orientation relative to the rear axle, not the pinion. In both cases, the essential factor is that the module of the crown gear matches the M50 of this pinion and that the motor axle is 2 mm.

The Scaleauto SC-1014 is a 14-tooth Module 50 nylon pinion gear for 2 mm standard motor axles, sold in a pack of 4 units. Designed for slot car preparation and competition, this high-durability nylon pinion delivers smooth, quiet gear engagement and excellent wear resistance. Compatible with any M50 crown gear, it is a reliable choice for club racers and slot car builders looking for consistent transmission performance.
