Product Description
The 7x2 Pulley Wheel is a robust mechanical component designed for power transmission, belt-driven systems, and heavy-duty robotic platforms. With a generous 7cm diameter, this wheel provides a significant mechanical advantage, allowing for high-torque output when used in pulley-reduction systems. The 6mm center bore is precision-sized to fit common DC geared motors (like the RS-775 or high-torque planetary motors) and 6mm steel axles. Constructed from high-impact reinforced material, this wheel is built to withstand the stresses of belt tension and load carrying, making it a versatile choice for DIY conveyor belts, rope-lifting mechanisms, and custom RC vehicle drivetrains.
Key Features
High Torque Transfer: The large 70mm diameter is ideal for increasing the "torque" of a motor-driven system when used with a smaller drive pulley.
Precision 6mm Bore: Fits securely onto standard 6mm shafts, ensuring minimal "wobble" or eccentric rotation during high-speed operation.
Durable Construction: Made from wear-resistant materials that can handle the friction of rubber belts, ropes, or flat timing belts.
Multi-Purpose Hub: The wide 2cm face provides enough surface area for various belt types or can be used as a friction-drive wheel in tracked robot designs.
Lightweight Design: Despite its size, the wheel is engineered with a spoke or webbed structure to minimize rotational inertia, allowing for faster motor response.
