Plastic crown gears for DIY models

This pack supplies twenty model 102A plastic crown gears designed for small-motor projects. Each gear has ten teeth, a 0.5 modulus and a six-millimetre outer diameter. They are intended for hobbyists building RC cars, model robots or classroom demonstrations of gear ratios.

Suits hobbyists and educators.

These gears fit light-duty science and hobby builds where a compact reduction gear is needed. They are not suited for high-torque drivetrains, continuous heavy loads or any application requiring metal-grade strength or precision meshing beyond the stated specification.

Ten-tooth count sets the reduction ratio

The ten-tooth count combined with the 0.5 modulus defines the gear ratio and meshing compatibility for your build. Verify that the mating pinion or worm matches this tooth count and modulus before purchase.

Questions about this item

What does the .5 modulus mean for gear meshing?

The .5 modulus sets the tooth pitch so these 10-tooth gears mesh correctly with other .5 modulus gears in RC cars or robots.

What shaft diameter fits the 2 mm hole?

The 2 mm bore accepts standard 2 mm motor shafts used in small DIY robotics and RC models.

How do I secure the gear onto the motor shaft?

Press the gear onto the 2 mm shaft and tighten the motor’s set screw or add a drop of thread-lock adhesive to prevent slipping.
