  • TypeOther Accessories
  • 20 gears in one pack for multiple builds

20-piece plastic spur gear set

This pack contains 20 white plastic spur gears designed for DIY model building and gearbox construction. Each gear has 8 teeth and measures 5mm by 5mm overall. The 2mm aperture fits directly onto a 2.0mm motor shaft. They are sold new and intended for hobbyist assembly.

2mm bore limits shaft compatibility

The gears only accept a motor axle with a 2.0mm diameter, so they cannot be used on larger or smaller shafts without modification. Plastic construction means they are suited to low-torque applications such as small RC vehicles or lightweight mechanisms. They are not designed for high-load drivetrains.

Eight-tooth count fixes the ratio

With exactly 8 teeth per gear, the reduction or multiplication ratio is locked to this count when paired with another gear. Builders who need a different tooth count for a specific gear ratio cannot use this set. The fixed specification makes the part suitable only for projects matching this exact profile.

Questions about this item

How many gears come in one pack and what shaft size do they fit?

The pack contains 20 white plastic spur gears, each with an 8-tooth design and a 2mm aperture that matches a 2.0mm motor shaft.

What does the 5mm x 5mm size tell me about how the gear will sit in my model?

The gear measures 5mm in diameter and 5mm in thickness, so it occupies a compact square footprint inside a gearbox or chassis.

What does the 2mm aperture limit when I connect the gear to a motor?

The 2mm bore only accepts shafts of exactly 2.0mm; larger or smaller shafts will not engage correctly.
