Tamiya 70121 Pulley Unit Set - STEM Pulley Kit  [70121]

Tamiya 70121 Pulley Unit Set - Practical Mechanics Lab

The Tamiya 70121 Pulley Unit Set gives hobbyists and students a clear, hands-on route into basic mechanical systems. This education-oriented kit helps users visualise how pulleys interact in assemblies and suits group projects, classroom demos, or solo bench work.

Kit Contents and Uses

The set supplies five different pulleys, a universal arm, pulley mounts, plus a motor and motor mount box so you can build multiple pulley arrangements. Those parts let you test motion, torque and mechanical advantage in simple rigs, and you can combine the set with other Tamiya construction or robotics modules to expand experiments.

Learning Outcomes and Compatibility

Well suited to beginners and experienced hobbyists, the Tamiya 70121 Pulley Unit Set promotes hands-on exploration of force and motion. Compatibility with a wide range of Tamiya components makes it a flexible addition to evolving projects and practical engineering exercises.
