TeacherGeek Accessories - Pulley Set Mixed

This Mixed Pulley Set from TeacherGeek opens up exciting opportunities for students to explore the world of simple machines, mechanical advantage, and power transmission. Unlike traditional pulleys that require gluing or custom attachments, these uniquely designed TeacherGeek pulleys feature a splined centre that securely presses onto a dowel shaft, offering a reliable grip and easy removal. Students can revise their designs on the fly-an essential part of real-world engineering and problem-solving.

Designed with a variety of sizes, these pulleys allow experimentation with gear ratios, speed, and force. Their non-slip design also enables the use of rubber bands or string to transfer power between rotating components. Whether used in classroom demonstrations or open-ended maker projects, these pulleys support active, hands-on learning with genuine mechanical components.
