Tamiya 70272 Differential Drivetrain Module for Educational Kits  [70272]

Clear-housed Tamiya 70272 differential for classroom use

This differential gear unit serves as a spare component for Tamiya educational construction models. Its bevel-gear layout permits different rotational speeds on paired driven shafts, allowing inner and outer shafts to turn independently when negotiating bends. The transparent casing makes internal gear movement visible, supporting inspection and teaching of gear mesh and geometry.

The unit uses low-friction internal gears and transfers power via three metal 3 mm hex shafts. It is built to integrate with separately sold Universal Plates and Universal Arms from the Tamiya Educational Construction Series, simplifying installation where a compact differential is required.

Maintenance-friendly features include removable screws for service access and a factory-applied lubricant to minimise initial wear. This item is intended for educators, hobby builders, and collectors who need a compact, observable differential for demonstration models or replacement in compatible assemblies.

The 70272 differential is a compact, serviceable unit that provides visible gear action for educational demonstrations and reliable replacement in compatible Tamiya assemblies.
