Product Description (Detailed):

The 25T Spur Gear is a precisely molded plastic gear designed for mechanical motion transfer in robotic drive systems, gearboxes, and DIY mechanical setups. Its 40mm diameter makes it suitable for moderate torque tasks, while the 6mm bore fits most standard DC motor shafts or shaft couplers.

The gear’s 12mm thickness allows robust engagement with mating gears, ensuring smooth, backlash-free transmission in robot arms, differential systems, motorized carts, or custom 3D-printed mechanisms.

Perfect for students, makers, and robotics hobbyists building gear trains or experimenting with mechanical transmission ratios.

How to Use:

1. Insert onto a 6mm shaft (DC motor, geared motor, or coupling).

2. Pair with a compatible spur or pinion gear to build gear trains.

3. Use with L-shaped motor brackets or 3D-printed supports.

4. Ideal for projects needing speed reduction or torque increase via gear ratios.

Pro Tip: Use multiple gears with varying tooth counts to customize output RPM and torque for your robot.
