Offset line crown 24Z brass insert

The Offset crown gear from Slot.it designed for those who fine-tune every detail of the transmission

The Offset line 24Z crown gear with bronze insert (reference SIGO24-BZ) is a transmission component from Slot.it aimed at setups with the motor in Inline position — that is, with the motor longitudinally aligned with the rear axle — using an Offset chassis. This configuration lowers the car's centre of gravity and is very common in club and competition setups.

Features and function

• 24 teeth: a tooth count that offers an efficient balance between top speed and acceleration on most tracks.
• Bronze insert: bronze is a classic material in precision transmission components. It provides a smooth fit on the axle, some self-lubricating capability, and good durability under continuous use.
• For 2.38 mm axle: standard diameter in the Slot.it rear axle range, widely used in the competitive slot racing world.
• Exclusive use with Offset chassis: this crown gear is not interchangeable with Sidewinder or Anglewinder configurations. It is specifically designed for the geometry of the Slot.it Offset chassis.

Compatibility and installation

As a specific component of the Slot.it Offset line, its compatibility is limited: it requires an Offset chassis from the same brand and a 2.38 mm axle. Before installation, it is advisable to check that the motor pinion corresponds to the crown gear's module to ensure clean engagement without play.

The bronze insert allows for a precise fit on the axle. If you detect any lateral play or vibration in the transmission at any point, check the tightness and condition of the axle before dismissing the crown gear.

Who is this crown gear for?

It is intended for club racers or enthusiasts who assemble or tune their own chassis with Inline motors and Offset chassis, and who want to keep the transmission components within the Slot.it ecosystem to ensure consistent tolerances and performance.

Frequently asked questions

Can I use this crown gear with a Sidewinder or Anglewinder chassis?

No. The Offset line crown gear is designed exclusively for the geometry of the Slot.it Offset chassis. Using it with other configurations would compromise the engagement and proper functioning of the transmission.

What advantage does the bronze insert have over other materials?

Bronze offers a good combination of durability, dimensional precision, and some self-lubricating capability, making it suitable for components that work in continuous contact with the axle. It is a common standard in precision transmission components in competitive slot racing.

What pinion should I use with this 24-tooth crown gear?

The pinion must have the same module as the crown gear to ensure correct engagement. Slot.it offers a range of pinions compatible with its Offset crown gear line. Check the appropriate combination according to the motor you are using.

Do I need to lubricate the bronze insert?

Bronze has self-lubricating properties, but a small amount of specific slot transmission lubricant applied sparingly can extend the life of the component and improve smoothness of rotation. Do not overuse the lubricant to avoid it migrating to the braids or guide.

Is the 2.38 mm axle a common standard?

Yes. The 2.38 mm diameter is one of the most widespread in competitive slot racing, especially in chassis and axles from Slot.it itself. Ensure that your chassis axle matches this diameter before installing the crown gear.

The Slot.it SIGO24-BZ is a 24-tooth Offset inline crown gear with a bronze insert, designed for 2.38 mm axles and exclusively compatible with Slot.it Offset motor mounts. A precision transmission component for club racing and competitive slot car builds, ensuring smooth gear engagement and consistent performance on track.
