CNC Plastic Front Wheels 3/32 17 mm 0.3 g

NSR Front Wheels: CNC Precision and Minimal Weight for the Front End

The NSR5024 front wheels are machined from high-precision plastic using CNC processes, ensuring excellent concentricity and a uniform finish in each unit. With a diameter of 17 mm, a 3/32" axle, and a weight of just 0.3 gr, they represent a direct option for those looking to reduce unsprung mass on the front axle without sacrificing dimensional integrity.

Main Features

• Material: CNC machined plastic
• Diameter: 17 mm
• Axle: 3/32"
• Weight: 0.3 gr per unit
• Reference: NSR5024

Function and Performance

The front axle of a slot car has a direct influence on braking behaviour and stability during direction changes. A lighter wheel reduces rotational inertia, resulting in sharper response and less resistance to free rotation. NSR's CNC plastic offers the right balance between sufficient stiffness and minimal weight, without the deformations that can occur in lower tolerance moulded parts.

Compatibility and Installation

These wheels are designed for 3/32" axles, the most widespread standard in the NSR range and compatible with a wide variety of chassis on the market. Before installation, it is advisable to check that the fit on the axle is correct: neither too loose, which would create lateral play, nor excessively tight, which could hinder centring. NSR has a well-documented spare parts catalogue that makes it easy to find the most suitable combination of wheel, tyre, and axle for each configuration.

Installation and Preparation

For optimal installation, it is recommended to mount the corresponding 17 mm tyre onto the wheel and lightly turn it if a final diameter adjustment is sought. The lightness of the plastic makes the turning operation straightforward and controlled. Given the low weight of the part, paying attention to the balancing of the wheel-tyre assembly will contribute to smoother rolling and reduce vibrations on the straights.

Ideal for…

This reference is especially useful for enthusiasts and competitors working on the preparation of the front end looking to minimise weight. It is also practical as a maintenance replacement when the original wheels show wear or damage, maintaining the exact factory specification.

Frequently Asked Questions

Are these wheels sold individually or in pairs?

The specification indicates the characteristics per unit. Check the exact quantity included in the packaging in the product description or contact us if you have any questions before ordering.

Are they compatible with NSR 17 mm tyres from other references?

In principle, yes, as long as the tyre is designed for a 17 mm diameter wheel. Check the NSR catalogue to confirm the most suitable tyre reference for this wheel.

Is the 3/32" axle the usual standard in NSR cars?

Yes, the 3/32" (approximately 2.38 mm) is the most common axle diameter in the NSR range and in much of the competitive slot market. Always check the specifications of your chassis before choosing the wheel.

Can I use these wheels on the rear axle?

They are designed as front wheels. For the rear axle, NSR offers specific references with different sizes and characteristics adapted to the demands of traction and transmission. Do not confuse them to avoid fitting or performance issues.

What advantage does CNC plastic have over a metal wheel on the front axle?

The main advantage is weight: CNC plastic is significantly lighter than aluminium or brass, which reduces the unsprung front mass and improves cornering response. The mechanical strength of a metal is not needed on the front axle, making machined plastic a technically coherent solution.
