Tamiya 70141 Large Pulley Set - Classroom and Maker Kit  [70141]

Large Pulley Set Tamiya 70141 for model making and teaching

The Tamiya 70141 Large Pulley Set provides a selection of pulley sizes and power bands useful to builders and educators exploring mechanical systems. With 11mm, 25mm and 50mm pulley options, the set supports experiments in speed, torque and belt routing without needing specialised parts. Its straightforward components suit both lesson tasks and hobby bench work.

Compatibility and how the parts perform

The pulleys are intended to work together with Tamiya construction parts to create belt-driven mechanisms. The included power bands let you assemble working demos of pulleys and belts to show motion transfer and mechanical advantage in a tangible way. These parts are helpful for rapid prototyping of rotating linkages and simple machines.

Practical classroom and workshop applications

Useful in education and maker sessions, the set helps learners visualise gear ratios and belt-driven motion. Mixing the different pulley diameters makes it easy to set up comparative trials and hands-on exercises on load and speed effects.
