Stepped Pulley with Axle (Case of 10) – Multi-Diameter Physics Pulley for Simple Machines by GSC International Inc.
This Stepped Pulley with Axle set from GSC International is designed for demonstrating conservation of energy, mechanical advantage, and simple machine principles in physics classrooms. Each pulley features a durable plastic wheel paired with a steel rod axle and a smooth roller bearing hub for consistent performance during experiments.
With four stepped pulley diameters (1.5", 2", 2.5", and 4"), students can easily compare speed, force, and torque changes across different wheel sizes. The pulley connects quickly to a support stand using a right-angle clamp. Sold as a case of 10, it’s ideal for lab stations, classroom sets, and group learning.
