33z 16.8mm Crown Anglewinder

NSR 33z Anglewinder Crown Gear: Custom Transmission for Your Angle Configuration

The NSR6533 is a 33-tooth crown gear with a diameter of 16.8 mm, developed by NSR specifically for 15° anglewinder setups. Its purple colour immediately identifies it within the extensive NSR crown gear catalogue, facilitating workshop management and quick selection on the preparation bench.

Main Features

• Reference: NSR6533
• Number of Teeth: 33z
• Diameter: 16.8 mm
• Configuration: Anglewinder 15°
• Identifying Colour: Purple
• Recommended Pinions: NSR71XX series with a diameter of 7.5 mm

Function and Performance

In an anglewinder configuration, the motor is positioned at an angle to the rear axle, allowing for a combination of weight positioning advantages with efficient transmission. The NSR6533 crown gear is machined to fit precisely at this 15° angle, ensuring that the mesh with the pinion is clean and free from unnecessary play that could rob performance or introduce vibration.

With 33 teeth and a diameter of 16.8 mm, this crown gear offers a transmission ratio aimed at balancing top speed and acceleration, depending on the pinion it is paired with. It is one of the most versatile options within NSR's anglewinder range, suitable for a variety of track layouts.

Compatibility and Installation

This crown gear is designed for NSR cars and should be used with the NSR71XX series pinions with a diameter of 7.5 mm, which are recommended by the manufacturer to ensure correct meshing. Before installation, it is advisable to verify that the rear axle and the chassis allow for the necessary 15° angle to properly utilise this crown gear.

Common Mistakes

A common mistake is attempting to combine this crown gear with pinions from other series or different diameters than specified. The result is often poor meshing, increased wear, and loss of efficiency in the transmission. Always use the recommended NSR71XX pinions and adjust the spacing between the crown and pinion according to the manufacturer's guidelines.

Frequently Asked Questions

Which pinions are compatible with the NSR6533 crown gear?

NSR recommends using it with pinions from the NSR71XX series, which have a diameter of 7.5 mm. This combination ensures correct meshing for 15° anglewinder configurations.

What cars is this crown gear designed for?

It is designed for NSR cars that utilise an anglewinder configuration. Check that your car's chassis supports this type of mounting before installation.

What is the difference between an anglewinder crown and a sidewinder?

In a sidewinder configuration, the motor is parallel to the rear axle (transverse), whereas in an anglewinder, the motor is positioned at an angle to that axle. Each configuration requires specific crown gears to ensure correct meshing, so they are not interchangeable.

Does the purple colour have any technical function?

The colour identifies the reference within the NSR crown gear system, facilitating quick selection when working with multiple options on the preparation bench. It does not affect mechanical performance.

Can I use this crown gear on tracks of different systems?

The compatibility of the crown gear with the track is not relevant: the crown gear is mounted on the car. What determines compatibility with the rail is the chassis, guide, and braids of the car itself, not the crown gear.

The NSR6533 is a 33-tooth anglewinder crown gear measuring 16.8 mm in diameter, designed for 15° anglewinder motor configurations in NSR slot cars. Identified by its purple colour, it pairs with NSR71XX pinions (7.5 mm diameter) for precise and reliable gear mesh. A go-to upgrade for NSR slot car enthusiasts looking to fine-tune their transmission ratio for club racing or track days.
