Gear Specifications

These plastic crown gears carry model number 092A and feature nine teeth with a 0.5 modulus. The outer diameter measures 5.5 mm, thickness is 5 mm and the bore is 2 mm. They are supplied as a pack of fifty pieces for DIY projects.

Build And Fit

Moulded from plastic, the gears are lightweight and intended for low-torque applications such as RC cars, model robots or windmill demonstrations. The 2 mm bore slides onto standard small motor shafts without additional hardware, making assembly straightforward for hobbyists and educational builds.

Operating Characteristics

Plastic construction keeps running noise low and eliminates the need for lubrication in typical hobby use. Power draw is determined entirely by the chosen motor, while the gear material limits heat build-up during intermittent operation. The parts are new and ready for immediate use in science or family DIY projects.

Questions about this item

What modulus and tooth count define the 092A gear's meshing standard?

What are the exact outer diameter, thickness and bore size needed for this gear to fit a motor shaft?

The gear has a 5.5 mm outer diameter, 5 mm thickness and a 2 mm bore.

How do you install the 092A gear on a motor shaft and what common step is missed?

Press the 2 mm bore onto the motor shaft and secure with a set screw or adhesive; forgetting to fix the gear so it spins freely is the usual error.
