32d Crown Gear Anglewinder Ø18mm

Lightweight aluminium anglewinder crown gear to take your transmission to the next level

The 32-tooth Anglewinder crown gear Ø18 mm (ref. SIGA1832E) is specifically designed for anglewinder configurations, where the motor operates at an angle to the rear axle. This geometry requires a well-calibrated crown gear that transmits rotation accurately, without play or vibrations that could ruin track performance.

Features and highlights

• Teeth: 32 t.
• Diameter: Ø18 mm
• Material: lightweight aluminium
• Compatible axle: 2.38 mm
• Fixing: M2 allen screw
• Configuration: anglewinder

Lightweight aluminium reduces the rotating mass in the drivetrain, resulting in a more agile response to acceleration changes and lower inertia when braking. In an anglewinder setup, where the motor-pinion-crown assembly operates at a specific angle, having a precise and well-balanced crown gear makes a tangible difference in the car's behaviour.

Assembly and preparation

The fixing with an M2 allen screw ensures a secure and repeatable tightening. When mounting this crown gear, it is advisable to check that the axle is perfectly clean and free of burrs before inserting the part, to ensure concentricity. Once in place, adjust the screw with the correct torque: not too loose —which would create play— and not too tight —which could mark the axle and complicate future changes—.

Always check the engagement with the pinion before considering the job finished: a correct mesh, without excessive tightness or play, is the foundation of a quiet and efficient transmission.

Compatibility

As this is a crown gear for a 2.38 mm axle in an anglewinder configuration, it is compatible with setups that use that standard axle diameter. Before ordering, confirm the diameter of your axle and the gear ratio you are looking for by combining this crown gear with the corresponding pinion from your motor.

Common mistakes

• Confusing sidewinder crowns with anglewinder: the motor mounting angle determines which type you need; they are not interchangeable without adjusting the chassis geometry.
• Not verifying the axle diameter before assembly, which forces disassembly and reordering.
• Over-tightening the M2 allen screw, damaging the axle or deforming the crown gear housing.

Frequently asked questions

Does this crown gear work for a sidewinder or inline configuration?

No. It is specifically designed for anglewinder setups, where the motor is positioned at an angle to the rear axle. For sidewinder or inline configurations, there are crown gears with different geometries; consult the appropriate reference according to your chassis.

What gear ratio do I get with 32 teeth?

The final gear ratio depends on the number of teeth on the pinion you mount on the motor. By dividing the teeth of the crown gear by those of the pinion, you obtain the ratio. A higher ratio results in more top speed; a lower ratio provides more acceleration. You will need to calculate the exact value with your specific pinion.

Does lightweight aluminium withstand intensive club use?

Yes. Lightweight aluminium offers a good balance between reduced weight and mechanical strength for regular club track use. In highly demanding competition, it is advisable to periodically check the condition of the teeth and the tightness of the fixing screw.

What allen key do I need for the M2 screw?

An M2 allen screw generally requires a key of 1.5 mm. Confirm the exact size with your set of keys before proceeding with the assembly to avoid rounding the screw head.

Can I use this crown gear on a 3/32" (2.38 mm) axle?

Yes. The diameter of 2.38 mm is equivalent to the standard 3/32 inches, common in many slot car chassis and axles on the market. It is the size for which this crown gear is designed.

The SIGA1832E is a 32-tooth anglewinder crown gear, 18 mm diameter, machined in lightweight aluminium for 2.38 mm (3/32") axles and secured with an M2 allen screw. A precise, low-inertia transmission component for anglewinder slot car builds, compatible with standard 3/32" rear axles used across a wide range of slot car chassis.
