AW 32T Crown 16 mm: NSR Balanced and Lightened Transmission for Anglewinder

The reference NSR6632E is a 32-tooth crown specifically designed for anglewinder configurations, with a diameter of 16 mm and made from high-performance plastic. NSR offers it in a balanced and lightened version, meaning it has undergone a mass adjustment process to eliminate unwanted vibrations at high revolutions, which makes a difference as soon as the motor starts to spin quickly.

Function and Performance

In a slot car with anglewinder motorisation, the crown works in constant communication with the motor pinion. Any imbalance in its mass causes micro-vibrations that result in loss of traction, premature gear wear, and ultimately worse lap times. The balanced version from NSR eliminates this problem from the outset: the part leaves the factory with compensated masses, ready to mount without additional work on the bench.

The lightened version, on the other hand, reduces the rotational inertia of the transmission. This is particularly noticeable in the response to acceleration and in recovery after corners: the car reacts quicker and more smoothly.

Compatibility

This crown is designed for anglewinder setups with NSR chassis and motors. With 32 teeth and 16 mm diameter, it is important to verify that your motor pinion is compatible in module and pitch before installation. NSR offers a wide range of pinions and crowns that allow you to adjust the gear ratio for each type of circuit.

Installation and Preparation

• Check the alignment between pinion and crown before gluing or permanently fixing.
• Review the lateral play: neither too tight (noise and wear) nor excessively loose (jumping and loss of power).
• Apply a minimal amount of specific slot gear lubricant; excess attracts dirt and slows down the transmission.
• As it is plastic, it does not require prolonged running-in, but a couple of gentle sessions at the start help to settle the contact with the pinion.

Ideal for…

This crown fits those who fine-tune their cars with precision: the club racer looking to reduce every mechanical variable, the builder who assembles NSR kits from scratch, and the enthusiast who already knows that the transmission is one of the critical points of performance. It is not a display piece; it is a working part.

Frequently Asked Questions

What is the difference between a standard crown and a balanced and lightened crown?

A standard crown may have slight mass differences around its perimeter due to the manufacturing process. The balanced version corrects these differences, reducing vibrations at high RPM. The lightened version, in addition, removes non-structural material to reduce inertia and improve acceleration response.

Is this crown compatible with any anglewinder chassis?

It is designed for the NSR range in anglewinder configuration. To use it with other chassis, you must verify that the gear module, diameter, and pitch are compatible with the pinion you intend to use.

Which pinion works best with this 32-tooth crown?

The choice of pinion depends on the gear ratio you are looking for for each circuit. NSR offers pinions with different tooth counts to adjust that ratio. In technical circuits, a shorter ratio (pinion with more teeth) is usually preferable; in fast circuits, a longer ratio. Consult the NSR ratio chart to fine-tune the setup.

Does the plastic material hold up in competition?

Yes. NSR uses specific technical plastics for slot gears, designed to withstand competitive use conditions. The key is to maintain proper lubrication and periodically check for wear.

Do I need special tools to install it?

The installation is straightforward with the usual slot preparation tools. A crown puller and a lateral play gauge facilitate the work and prevent damage to the part or the axle.
