26Z angle crown gear

The Slot.it anglewinder crown gear for fine-tuning your gear ratio

The crown gear SIGA1626-PL is an engineering plastic component manufactured by Slot.it with 26 teeth, designed for anglewinder setups, where the motor is positioned at an angle relative to the rear axle. With a shaft diameter of 2.38 mm, it fits snugly into standard mounts from the brand and many compatible prepared chassis.

Features and function

• 26 teeth: an intermediate number that allows balancing acceleration and top speed depending on the pinion it is paired with.
• Plastic material: lightweight, quiet, and with a smooth engagement that reduces the load on the motor.
• 2.38 mm shaft: standard measurement in the Slot.it ecosystem, facilitating integration without modifications.
• Designed for anglewinder: the tooth geometry is optimised for the attack angle specific to this motor configuration.

Compatibility and installation

As part of the official Slot.it catalogue, this crown gear is intended to work alongside pinions from the same range. For correct engagement, it is advisable to verify that the module of the chosen pinion matches that of this crown gear. The adjustment of backlash —the play between pinion and crown gear— is crucial: too tight generates heat and wear, while too loose introduces vibrations and power loss.

If you are building or preparing an anglewinder chassis from scratch, this 26Z crown gear is a common starting point for medium-long track layouts, where a slightly longer gear ratio than that offered by a lower-toothed crown is desirable.

Installation and preparation

• Insert the crown gear onto the shaft ensuring it is well seated and perpendicular.
• Secure with adhesive or the appropriate retention system depending on the type of shaft.
• Check the lateral alignment with the pinion before closing the chassis.
• Run a few laps at low speed to verify that the engagement is smooth and without hard spots.

Common mistakes

• Confusing anglewinder configuration with sidewinder or inline: this crown gear is designed for anglewinder (motor at an angle); do not interchange it with straight profile crown gears intended for sidewinder or inline without checking module compatibility.
• Not checking the backlash: overly forced engagement is the most common cause of premature wear in plastic crown gears.
• Installing on a different shaft size: always verify that your shaft is 2.38 mm before installing this part.

Frequently asked questions

Is this crown gear suitable for sidewinder or inline configurations?

It is not intended for those configurations. The reference SIGA1626-PL is specifically designed for anglewinder, where the motor is positioned at an angle relative to the rear axle. For sidewinder or inline, consult the specific references from Slot.it for those geometries.

Which pinions work best with this 26-tooth crown gear?

The choice of pinion depends on the circuit and the motor used. As a general rule, pinions between 8 and 11 teeth are the most common for club tracks with this crown gear. The smaller the pinion, the greater the acceleration; the larger, the higher the top speed.

Can it be used on chassis from other brands?

As long as the shaft is 2.38 mm and the pinion module is compatible, it can be installed on chassis from other brands. Always check the alignment and the play of the engagement.

How long does a plastic crown gear last compared to a metal one?

Plastic crown gears have a slightly shorter lifespan than metal ones under intensive use, but they provide quieter engagement and are gentler on the pinion. For club use or regular competition, it is advisable to check them periodically and replace them at the first sign of wear on the teeth.

The Slot.it SIGA1626-PL is a 26-tooth plastic crown gear engineered for anglewinder motor configurations in 1/32 slot car racing. Designed for a 2.38 mm axle, it delivers smooth and precise power transmission. A trusted choice for club racers and hobbyists building or tuning anglewinder slot car chassis. Compatible with standard Slot.it pinion gears within the same module range.
