nylon pinion for 2 mm axle: reliable transmission with module 50

The Scaleauto SC-1008 is an 8-tooth pinion made from high-durability nylon, with module 50 and specifically designed for motors with a standard 2 mm axle. It is supplied in a pack of 4 units, which is very practical for preparing multiple cars or having spare parts on hand.

Main features

• Number of teeth: 8
• Module: 50
• Material: high-durability nylon
• Compatible axle diameter: 2 mm (standard axle)
• Pack contents: 4 units

Function and performance

The pinion is the link between the motor and the crown gear: it defines the gear ratio and, therefore, directly influences the top speed and torque on track. With 8 teeth and module 50, this pinion targets high gear ratios, designed for short tracks or configurations where acceleration and motor response are prioritised.

The high-durability nylon offers several advantages over metal in certain contexts: it absorbs vibrations better, operates with less noise, and is tolerant of small misalignments between pinion and crown gear, which extends the life of the transmission assembly. Additionally, it does not require lubrication as frequently as metal pinions.

Compatibility and installation

This pinion is designed for any slot motor that has a standard 2 mm axle, the most common diameter in the competitive and recreational slot world. To complete the transmission, it must be paired with a compatible module 50 crown gear; Scaleauto offers several references of crown gears in this module.

Installation is straightforward: it fits onto the motor axle and is secured using the usual method (pressure or adhesive, depending on the chassis and clearance). It is advisable to always check the mesh with the crown gear before finalising the installation, ensuring minimal play but without excessive tightness.

Common mistakes

• Mixing pinions and crown gears of different modules (e.g., module 50 with module 40): the teeth do not mesh correctly and wear is premature.
• Ignoring lateral alignment between pinion and crown gear: although nylon is tolerant, excessive misalignment causes uneven wear.
• Over-tightening the pinion onto the axle: it can deform the nylon and cause play after a few sessions.

Frequently asked questions

What type of motor is this pinion suitable for?

For any slot motor with a standard 2 mm output axle, whether in sidewinder, inline, or anglewinder configuration.

What crown gear should I use with this pinion?

You need a crown gear with module 50. The number of teeth on the crown gear will determine the final gear ratio; more teeth on the crown gear compared to the pinion will result in more torque and less top speed, and vice versa.

How many units are included in the pack?

The SC-1008 pack includes 4 units.

Does nylon withstand competitive use?

Yes. Scaleauto specifies that it is made from high-durability nylon, suitable for both recreational use and club sessions. In high-level competition, some preparers prefer steel pinions for metal crown gears as well; the choice depends on the crown-pinion set you use.

Does it require lubrication?

Nylon works well with minimal lubrication or even dry, although a small amount of specific slot transmission lubricant extends the life of the assembly and reduces noise.

The Scaleauto SC-1008 is an 8-tooth module 50 nylon pinion gear for standard 2 mm motor axles, supplied in a pack of 4 units. A reliable and durable transmission component for slot car racing, compatible with sidewinder, inline and anglewinder motor setups. Ideal for club racers and hobbyists looking for quiet, low-maintenance drivetrain parts.
