The Electroboat 7cm Dia x 4cm Width Plastic Pulley Wheel is specifically manufactured for robotics applications requiring smooth belt transmissions, caterpillar track drives, or winch mechanisms. Featuring an overall diameter of 70mm and a wide 40mm face, this pulley provides ample surface contact to prevent belt slippage under heavy torque loads.

Made from high-density, impact-resistant engineering polymer, the wheel comes equipped with an internal 6mm center shaft hub designed to couple directly with standard center-shaft DC geared motors. Whether you are constructing a tank tread robot chassis, a custom conveyor belt system, or a mechanical crane, this pulley wheel delivers balanced rotation and long-lasting durability.

Key Features and Benefits

• Extra-Wide 40mm Profile: Perfect for driving wide rubber tracks, timing belts, O-rings, or flat conveyor belts.

• 6mm Center Shaft Fitting: Connects directly onto standard 6mm D-shaft or round shaft DC geared motors with a locking set screw.

• Integrated Guide Channel Groove: Helps keep belts and tracks centered during continuous high-speed rotation.

• Durable Polymer Construction: Lightweight yet tough enough to sustain payload pressure without wearing out motor bearings.

• Smooth Surface Finish: Reduces belt friction and wear, increasing overall motor power efficiency.

How to Use

1. Align the center 6mm mounting hole of the pulley wheel with the output shaft of your 6mm DC geared motor.

2. Slide the wheel smoothly onto the shaft until seated against the motor collar.

3. Tighten the hub set screw using a suitable screwdriver to securely lock the pulley onto the motor shaft.

4. Mount your timing belt, rubber track, or drive belt onto the outer circumference groove.
