Tamiya 72008 Worm Gearbox HE 4-Speed Educational Gear Unit  [72008]

Introduction to the Tamiya 72008 Worm Gearbox HE

The Tamiya 72008 4-Speed Worm Gearbox HE is part of the STEM series and is aimed at learners and hobbyists who want to study gear reduction and torque management. It offers a hands-on way to test mechanical principles in small builds.

Gear ratios and adjustability

The gearbox provides four selectable ratios: 84:1, 216:1, 555.4:1, and 1428.2:1, giving a wide span between speed and torque. Changing which gears are engaged allows quick reconfiguration to suit testing conditions or different mechanisms.

Motor compatibility and assembly

An included Type 260 motor supplies reliable power for demonstration and light-load tasks. The unit also accepts 130 and 140 motors with the supplied adapter, and it connects readily with other Tamiya Education Construction parts for modular builds.

Compact dimensions

At 31.5mm wide, 47mm tall and 49mm long, the gearbox is compact enough for confined layouts and fits neatly into many educational rigs and hobby assemblies.
