14z blue anglewinder plastic pinions

NSR 14-tooth nylon pinions for anglewinder: lightweight and precise transmission

When it comes to fine-tuning the transmission of a slot car with an anglewinder motor configuration, the choice of pinion makes a real difference. These NSR 14-tooth nylon pinions offer a balance between lightness, smooth rotation, and durability, covering everything from club car preparation to the most demanding setups.

Main features

• Number of teeth: 14z
• Diameter: 7.5 mm
• Material: nylon
• Configuration: anglewinder
• Colour: blue (quick visual identification)
• Contents: 4 units per pack

Function and performance

Nylon is the reference material for competition slot pinions when seeking quiet operation and slight vibration absorption. Unlike metal pinions, high-quality plastic reduces transmission noise and works smoothly against the crown gear, extending the lifespan of the gear set. With 14 teeth and a diameter of 7.5 mm, this pinion fits into the mid-range of gear ratios, suitable for both technical tracks with many curves and mixed layouts.

Compatibility and mounting

These pinions are specifically designed for anglewinder mounts — a configuration where the motor is angled relative to the rear axle — and are compatible with the NSR range of motors and chassis designed for this layout. Before mounting, it is advisable to check that the inner diameter of the pinion fits the motor shaft of your chassis and that the lateral displacement with the crown gear is correct to ensure a clean engagement.

Preparation and adjustment

To get the most out of any nylon pinion, it is recommended to perform a gentle run-in before demanding full performance. A light lubrication at the contact point with the crown gear — without excess, to avoid dirtying the track — prolongs the life of the set and keeps the transmission smooth. Checking the axial play of the pinion on the shaft and adjusting the crown-pinion distance are basic steps that make a difference in the car's response.

Common mistakes

• Mounting the pinion without checking alignment with the crown gear: causes premature wear and noise.
• Using excessive lubricant: attracts dirt and can cause the transmission to slip.
• Ignoring the initial run-in: forcing a new pinion from the start reduces its lifespan.
• Confusing the anglewinder reference with the sidewinder: both configurations use different pinions; ensure you select the correct model for your setup.

Frequently asked questions

How many pinions are included in the pack?

The pack contains 4 units, allowing for spare parts to be available or equipping several cars at once.

Is nylon as durable as metal?

For regular use in slot — both recreational and club competition — nylon offers more than sufficient durability. Additionally, it is quieter and smoother with the crown gear than metal, which can extend the lifespan of the entire gear set.

Can I use this pinion in a sidewinder or inline configuration?

No. These pinions are specifically designed for anglewinder mounts. For sidewinder or inline configurations, NSR has specific references adapted to each motor layout.

What crown gear is most suitable to combine with a 14-tooth pinion?

The choice of crown gear depends on the gear ratio you are looking for and the characteristics of the track. NSR offers a wide range of crown gears with different numbers of teeth; consult the gear ratio tables to find the optimal combination according to the type of circuit.

Does the blue colour have any technical function?

The colour primarily serves to visually identify the reference within the NSR pinion assortment, facilitating workshop organisation and quick selection during car preparation.
