Offset line crown 23Z bronze insert

Transmission designed for inline configuration with Slot.it Offset pod

The SIGO23-BZ crown gear from Slot.it is a 23-tooth transmission component with a bronze insert, specifically developed for inline mounting on an Offset pod. A clear choice when looking for a specific gear ratio with the reliability and machining finish that characterise Slot.it in its competition components.

Technical specifications

• Number of teeth: 23Z
• Insert: bronze
• Compatible axle diameter: 2.38 mm
• Exclusive use: Offset pod (motor in inline position)

Function and performance

The bronze insert is one of the elements that most influences the durability and behaviour of the transmission. Bronze offers excellent wear resistance with the axle, reduces friction at the contact point, and allows for a precise fit without excessive play. In an inline configuration —where the motor operates in a longitudinal position, in line with the rear axle, favouring a lower centre of gravity— every tenth of efficiency in the transmission counts.

With 23 teeth, this crown gear sits in a versatile range within the common gear ratios in competitive slot racing. Combined with the appropriate pinion, it allows for tuning the motor response to the characteristics of each track: more acceleration on layouts with many short curves, or higher top speed on faster tracks with long straights.

Compatibility and installation

This crown gear is designed exclusively for use with the Slot.it Offset pod. It is not interchangeable with other pod configurations (Sidewinder or Anglewinder) without verifying geometry compatibility. The accepted axle is 2.38 mm, the standard commonly used in the brand's kits and transmission sets.

Before installation, it is advisable to check the condition of the axle, ensuring it is clean and free of burrs, to ensure that the crown gear is well centred and without play that could generate vibration or premature wear.

Common mistakes

• Attempting to mount this crown gear on a Sidewinder or Anglewinder pod: the geometry is not suitable and the result will be incorrect meshing.
• Forcing the insert onto an axle with a diameter different from 2.38 mm: this can damage the insert or cause play in the transmission.
• Not aligning the crown gear and pinion correctly before securing the pod: poor alignment generates uneven wear and loss of efficiency.

Frequently asked questions

Can I use this crown gear in a Sidewinder configuration?

No. This crown gear is designed exclusively for motors in the inline position mounted on Slot.it Offset pods. For Sidewinder configurations, there are specific references from the brand.

What advantage does the bronze insert provide over other materials?

Bronze reduces friction with the axle and is more resistant to wear than softer materials. Additionally, it allows for a more precise and durable fit, resulting in a more efficient transmission over the long term.

Which pinions work well with this 23-tooth crown gear?

It depends on the gear ratio you are looking for. With a 9-tooth pinion, you would achieve an approximate ratio of 2.56:1, suited for tracks with long straights. With an 11-tooth pinion, the ratio would be shorter, gaining response in curves. Always consult Slot.it's recommendations for your specific motor and track.

Is it compatible with axles from other brands?

As long as the axle is 2.38 mm in diameter, the crown gear can work. However, to ensure the best results in terms of alignment and transmission, it is advisable to use it within the Slot.it component ecosystem.

When should the crown gear be replaced?

When visible wear on the teeth, excessive play in the transmission, or unusual noise while running is observed. A periodic visual inspection after track sessions is sufficient to detect it in time.
