Product Description The 8T Plastic Pinion Gear is a fundamental mechanical component used to transfer rotational power from a DC motor to a larger gear train. Specifically designed for small-scale toy motors and DIY hobbyist projects, this gear acts as the primary "drive" gear. It features a precision-molded 8-tooth profile that ensures high torque transmission even in the smallest gearboxes. Its compact size and 0.5 Modulus make it compatible with almost all standard hobby gear sets used in DIY cars, robots, and small appliances.

Key Features

  • Precision 8-tooth design for maximum mechanical advantage in small spaces.

  • Press-fit bore ensures a non-slip connection to 2mm motor shafts.

  • High-density plastic construction reduces operating noise and friction.

  • Standard 0.5 Modulus for universal compatibility with hobbyist gear kits.

  • Lightweight and durable, ideal for high-speed micro-motor applications.

Technical Details

  • Number of Teeth: 8

  • Modulus: 0.5 (Standard)

  • Shaft Diameter Compatibility: 2.0 mm (Hole size is ~1.95mm for friction grip)

  • Total Diameter: 5.0 mm

  • Gear Length: 5.0 mm

  • Operating Temperature: -10 to +70 degrees Celsius

  • Material Property: Low-friction, wear-resistant polyoxymethylene (POM)

Prototyping and Engineering Tips from Robogears

  • Installation Tip: To mount this pinion on a motor shaft, place the back of the motor on a solid surface to prevent the shaft from pushing through the back of the motor housing. Use a small pair of pliers or a hollow tube to press the gear onto the shaft evenly.

  • Reduction Ratios: As an 8T gear, this is typically used to drive a much larger gear (e.g., 40T or 56T). Driving a 40T gear with this 8T pinion provides a 5:1 reduction, significantly increasing the torque of your small toy motor.

  • Avoiding Slip: If you find the gear is spinning freely on the shaft after repeated removals, you can slightly roughen the motor shaft with sandpaper or add a tiny drop of high-strength thread-locker to restore the grip.

  • Gear Meshing: Ensure that the pinion is not pressed too tightly against the secondary gear. A tiny "backlash" (a very small gap) is necessary to prevent the motor from drawing excessive current and overheating due to friction.

Package Includes

  • 1 x 8 Teeth (8T) Plastic Pinion Gear
