10-tooth pinion 6mm (X2)

Two Slot.it 10-tooth pinions for fine-tuning the transmission in detail

The pinion is one of the most influential components in the behaviour of a slot car: it affects acceleration, top speed, and cornering response. This pack includes 2 Slot.it 10-tooth pinions with a diameter of 6 mm (reference SIPI6010O), designed for those who want to precisely control every variable of their drivetrain.

Main features

• Number of teeth: 10
• Diameter: 6 mm
• Units per pack: 2
• Brand: Slot.it
• Reference: SIPI6010O

Function and performance

A 10-tooth pinion is an option aimed at prioritising top speed over acceleration. Combined with the appropriate crown gear, it allows for a longer gear ratio, which is particularly useful on circuits with long straights where the car needs to reach its maximum speed without overloading the motor in slow sections.

The Slot.it manufacturing guarantees the dimensional precision necessary for a clean and backlash-free engagement, which directly translates into transmission efficiency and more uniform and controlled wear of the crown gear.

Compatibility and installation

These pinions are designed to integrate into the standard transmission systems of Slot.it setups, both in sidewinder and anglewinder configurations. To confirm exact compatibility with your crown gear and axle, always consult the specifications of your transmission kit or chassis.

The 6 mm diameter is the most widely used standard in the brand's setups, so it fits with the common rear axles used in their chassis. Nevertheless, check the diameter of your axle before installation to ensure a proper fit.

Preparation and usage tips

Before mounting the pinion, ensure that the axle is clean and free from old lubricant residues or dirt. A good fit of the pinion on the axle will prevent slippage that could alter the car's behaviour during a race. Apply a minimal amount of lubricant to the engagement with the crown gear to prolong the lifespan of both components without compromising transmission efficiency.

Having 2 units in the pack allows for a spare ready for practice sessions or to test different gear ratio configurations without interrupting the car's preparation.

Ideal for…

This pinion fits particularly well with driver profiles competing in club championships or those who prepare their cars with technical criteria and seek to optimise response according to the layout. It is also practical for those who maintain a stock of transmission spares to avoid relying on delivery times during the racing season.

Frequently asked questions

What gear ratio do I get with a 10-tooth pinion?

The ratio depends on the number of teeth of the crown gear you combine it with. By dividing the teeth of the crown gear by those of the pinion, you obtain the ratio: for example, with a 27-tooth crown gear, the ratio would be 2.7:1. The higher the ratio, the more acceleration; the lower the ratio, the more top speed.

Is it compatible with all Slot.it chassis?

The 6 mm diameter is the most common in Slot.it setups, but we recommend checking the specifications of your specific chassis and axle before installation to ensure the fit is correct.

Can I use this pinion in sidewinder and anglewinder configurations?

Yes, Slot.it pinions are compatible with both motor configurations. The choice of teeth affects the gear ratio regardless of the motor layout.

What is the difference between a 10-tooth pinion and one with more teeth?

A pinion with more teeth, given the same crown gear, reduces the gear ratio and favours top speed. A pinion with fewer teeth increases that ratio and improves acceleration. The 10-tooth pinion is situated in the range of longer ratios, aimed at fast circuits.

What lubricant should I use for the engagement?

For slot transmission gears, it is recommended to use specific lubricants for plastic-metal or plastic-plastic in very small quantities. An excess of lubricant can attract dirt and deteriorate the performance of the transmission.
