32z 16.8mm Crown Gear Anglewinder

The NSR anglewinder crown that fine-tunes your transmission

The NSR6532 is a 32-tooth crown with a diameter of 16.8 mm specifically designed for anglewinder configurations, meaning those setups where the motor operates at an angle relative to the rear axle. This type of geometry seeks a balance between the acceleration response of the inline and the mass distribution of the sidewinder, and requires crowns with precise machining quality to ensure smooth and vibration-free transmission.

Main features

• Reference: NSR6532
• Number of teeth: 32z
• Diameter: 16.8 mm
• Configuration: Anglewinder (15º)
• Recommended pinions: NSR 71XX series, with a diameter of 7.5 mm

Compatibility and installation

This crown is designed for NSR cars that incorporate anglewinder configuration. NSR is one of the slot brands with the widest range of spare parts and accessories, making it easy to find the appropriate complementary pinion within its own catalogue. For this crown, the recommended pinions belong to the NSR 71XX series, with a diameter of 7.5 mm. Choosing the correct combination of crown and pinion directly influences the gear ratio, acceleration, and top speed of the car.

Before installation, it is advisable to verify that the rear axle, motor, and chassis are compatible with the 15º anglewinder configuration. A misaligned crown or excessive play can lead to premature wear and loss of efficiency in the transmission.

Function and performance

With 32 teeth, this crown provides a gear ratio aimed at delivering good torque on corner exits without sacrificing top speed on straights. It is a balanced option, useful for both technical circuits with many curves and mixed layouts. The diameter of 16.8 mm places it in an intermediate range within the NSR catalogue, suitable for most anglewinder setups of their chassis.

Common mistakes when working with anglewinder crowns

• Using pinions of a different diameter than recommended, resulting in poor meshing and vibrations.
• Not checking the lateral alignment between pinion and crown before permanently securing the motor.
• Over-tightening the fixing screw, which can deform the crown or create tension on the axle.
• Confusing this crown (anglewinder 15º) with crowns for sidewinder or inline configurations, which have different meshing geometries.

Frequently asked questions

Is this crown suitable for sidewinder or inline configurations?

No. The NSR6532 is designed for 15º anglewinder setups. Although it may physically appear similar, the angle of the teeth and the meshing geometry are optimised for this configuration. Using it in a sidewinder or inline setup would compromise the transmission.

What pinions should I use with this crown?

NSR recommends the pinions from the 71XX series, with a diameter of 7.5 mm. Using pinions from other series or different diameters may cause incorrect meshing and accelerated wear of both parts.

When should I change the crown on a slot car?

When excessive play in the meshing is observed, unusual noise in the transmission, or visible wear on the teeth. In competition cars, it is common to check it periodically, especially if it is heavily used on track.

Does the gear ratio significantly affect the car's behaviour?

Yes, notably. A crown with more teeth relative to the pinion reduces top speed but improves torque and acceleration. With 32 teeth, this crown offers an adequate balance for most club circuits, although the optimal combination always depends on the motor, the weight of the car, and the characteristics of the layout.

Is it compatible with chassis from other brands?

It is specifically designed for NSR cars. Compatibility with chassis from other brands depends on the diameter of the rear axle, the available space for the crown, and the motor configuration. We cannot confirm compatibilities outside the NSR ecosystem without prior verification.

The NSR6532 is a 32-tooth anglewinder crown with a 16.8 mm diameter, designed for NSR slot cars running an anglewinder motor configuration at 15 degrees. Compatible with NSR 71XX pinions (7.5 mm diameter), it delivers smooth and reliable power transmission for both club racing and recreational use. A precise, well-engineered gear replacement for NSR anglewinder setups.
