Tamiya 70222 Friction Power Unit Mechanical STEM Kit  [70222]

Practical Friction Drive: Tamiya 70222 for Makers

The Tamiya 70222 Friction Power Unit is a straightforward mechanical module designed for hobbyists and educators to add motion to projects. Its hands-on nature lets builders see and test energy storage and transfer in real time.

Core Mechanism and Visible Components

The package features a flywheel that captures kinetic energy when the drive wheel is rotated, passing that energy down a shaft to crank wheels. The transparent ABS shell gives a clear view of gears and motion, making it great for demonstrations.

Compatibility with Kits and Upgrades

Compatible with Tamiya Educational Construction Series elements, the unit can be combined with universal plates, arms, wheels and tracks to make working models. Use the included crank wheels or add optional wheels like the Slim Tire Set (Item 70193) to create a rolling example.

Classroom and Workshop Applications

Ideal for practical lessons on motion, force and energy, this friction unit supports iterative building and experimentation. It helps translate theoretical concepts into accessible hands-on activities.
