36-Tooth Crown for Raid Chassis: Nylon, Aluminium Core, and Secure Fixing

The CXM215 crown is specifically designed for raid chassis and combines two materials that complement each other very well in this type of application: the nylon absorbs impacts and reduces gear noise, while the aluminium core provides rigidity and ensures that the crown does not deform under the motor's load. The result is a reliable component for both club racing and intensive recreational use.

Main Features

• Number of Teeth: 36z
• Diameter: 19 mm
• Material: nylon with aluminium core
• Fixing: allen screw
• Application: raid chassis

Function and Performance

With 36 teeth and a diameter of 19 mm, this crown offers a gear ratio that enhances traction and stability on the rail sections typical of raid racing. The nylon dampens the irregularities of the engagement with the pinion and extends the lifespan of the transmission set, which is particularly valued when cars take hits or traverse more abrasive sections.

The aluminium core is the differentiating element compared to crowns made entirely of plastic: it prevents warping and maintains the geometry of the piece constant even when the nylon heats up after prolonged sessions. The allen screw fixing allows for precise tightening and facilitates disassembly without the risk of damaging the piece.

Assembly and Preparation

Assembly is straightforward: simply slide the crown onto the axle, align it correctly with the pinion, and tighten the allen screw with the appropriate key. It is advisable to check that there is no axial play once the screw is tightened and to verify the correct engagement with the pinion before each run. If you are going to adjust the gear ratio, consider the 19 mm diameter when calculating the crown/pinion ratio.

Compatibility

Designed for raid chassis. Before mounting, verify that the pitch of your chassis's pinion is compatible with this crown. If you have doubts about the pinion-crown combination for your setup, please consult us.

Common Errors

• Over-tightening the allen screw can damage the aluminium core or deform the nylon: tighten firmly but without forcing.
• Do not mix crowns of different pitches in the same transmission train; always check that the pinion and crown are of the same module.
• Periodically check the fixing screw, especially in cars that receive frequent impacts during raids.

Frequently Asked Questions

Is this crown compatible with any raid chassis?

It is designed for raid chassis, but compatibility depends on the pitch (module) of your chassis's pinion. Verify this information before purchase or consult us indicating your specific chassis.

What advantage does the aluminium core provide over a crown made entirely of nylon?

The aluminium core prevents the crown from deforming or warping with the heat generated during racing, maintaining stable geometry and engagement throughout the session.

What allen key do I need for the fixing screw?

The exact size of the allen screw is not specified in the manufacturer's data sheet. We recommend checking your chassis documentation or contacting us to confirm it.

Can I use this crown in modalities other than raid?

Although it is optimised for raid chassis, it can be mounted in any application that is compatible with its dimensions and pitch. Always verify compatibility with your transmission set.

How often should I check the allen screw?

In intensive use or in cars that suffer regular impacts, it is advisable to check the screw tightness after each session. For occasional recreational use, periodic checks are sufficient.
