The Pulley Wheel 6.5cm x 2cm for Gear Motor features a 65mm outer diameter and a 20mm wide rim, providing an ideal balance between speed, torque, and belt grip. In belt drive systems, pulley diameter directly affects performance—a larger driven pulley increases torque while reducing speed, whereas a smaller pulley increases speed at the expense of torque. This principle makes the pulley suitable for robotics, conveyor systems, automation mechanisms, and educational projects.
Designed with a 6mm center shaft hole, this pulley fits many commonly used dc gear motors, hobby gear motors, and plastic gearbox motors. Its lightweight plastic construction reduces rotational inertia, allowing the motor to start more smoothly while placing less load on the drive system. The 20mm wide grooved rim offers a larger contact area for the belt, improving grip and helping prevent belt slippage or misalignment during continuous operation. The groove supports rubber belts, O-rings, elastic belts, and flat belts commonly used in STEM projects.
Whether building a robot, a miniature conveyor, a mechanical model, or an educational prototype, this pulley wheel delivers reliable and efficient power transmission. Its durable design, easy installation, and compatibility with standard motors make it a perfect choice for students and makers.
