Nylon pinion Z12 x 7mm

Nylon Pinion Z12 x 7 mm: precise and silent transmission for your slot car

The nylon pinion is one of the most valued transmission components in the world of slot preparation. Its material — nylon — reduces gear noise compared to metal, better absorbs small alignment inaccuracies, and is gentler on both the crown gear and the motor, extending the overall lifespan of the drivetrain.

Features and Function

• Material: high-strength nylon
• Number of teeth: Z12
• Outer diameter: 7 mm
• Colour: green (facilitates quick identification on the workbench)
• Contents: bag with 4 units

The green colour code allows for quick distinction of this pinion from other modules or diameters in the spare parts drawer, a practical detail appreciated during preparation sessions or when working with multiple cars simultaneously.

Installation and Preparation

Before mounting the pinion, it is advisable to verify that the motor shaft diameter is compatible with the pinion hole. A clean fit, without excessive play or forced pressure, ensures the correct transmission of torque and avoids vibrations. Being made of nylon, it does not require lubrication at the contact point with the crown gear, although a minimal amount of grease on the mesh can prolong its performance during long track sessions.

The Z12 tooth count, combined with the corresponding crown gear, determines the final gear ratio of the car. A shorter ratio (small pinion / large crown) favours acceleration; a longer ratio favours top speed. With Z12, we find ourselves in a versatile usage zone, common in balanced configurations for mixed layouts.

Common Mistakes

• Forcing the pinion onto a shaft of incorrect diameter: this can deform the core and cause slipping or irregular transmission.
• Mixing pinions of different modules with incompatible crowns: although the tooth count may visually match, the mesh will not be correct.
• Forgetting to check the wear of the nylon pinion after intense sessions: it is a maintenance component and should be inspected regularly.

Frequently Asked Questions

What advantage does a nylon pinion have over a metal one?

Nylon generates less noise in the mesh, is lighter, and is gentler on the crown gear, reducing wear on both components. Conversely, its resistance to strong impacts is lower than that of metal, making it ideal for regular club or recreational use, and also in competition where regulations or configurations allow.

Which slot cars is this pinion compatible with?

Compatibility depends on the pinion module and the motor shaft diameter. With the provided data — Z12 and 7 mm outer diameter — it is necessary to verify that the module matches that of the car's crown gear. Consult your car or crown gear's technical specifications before mounting.

Can I use this pinion in Sidewinder, Inline, or Anglewinder configurations?

Yes. The type of motorisation does not directly condition the use of the pinion, as long as the module and shaft diameter are compatible. In any of the three configurations — Sidewinder (motor parallel to the rear axle), Inline (motor in line with the axle), or Anglewinder (motor at an angle) — the pinion serves the same transmission function.

Why are there 4 units in the bag?

Having multiple units is useful because the pinion is a wear component. Keeping spares on hand prevents unexpected downtime during track sessions or while preparing multiple cars.

Does the nylon pinion require lubrication?

In general, nylon works well dry, but a small amount of specific slot transmission grease at the contact point with the crown gear can reduce wear and heat generated during long sessions.
