Double Pulley – Twin 50mm Polypropylene Wheels with Aluminium Frame

This durable Double Pulley features two smooth‑running polypropylene wheels mounted within a robust aluminium frame, making it ideal for a wide range of classroom mechanics experiments. The frame is riveted for strength, ensuring long‑lasting durability, while the replaceable bearings deliver reliable, low‑friction performance in repeated demonstrations.

Each wheel has a diameter of 50mm, providing consistent movement when used with standard cords and masses. The twin‑wheel design makes this pulley perfect for building compound pulley systems and exploring how mechanical advantage changes with different configurations.
