Educational Rack and Pinion Tamiya 70235 for STEM Builds  [70235]

Tamiya 70235 Rack & Pinion - Product Summary

The Tamiya 70235 Rack & Pinion Gear Set is a compact, hands-on module from the Educational Construction Series, useful for makers and classroom activities. It demonstrates how rotational drive can be transformed into linear displacement for clear mechanical experiments.

Mechanics and Key Features

This set supplies two rack and two pinion gears to configure systems that translate rotary motion into straight movement. Racks are drilled with 30mm holes to allow free sliding as pinions engage. Builders can remove the separators between holes to extend the available stroke, while the pinion clutch helps avoid damage when a mechanism jams.

Integration and Project Ideas

Designed to work with other Tamiya Educational Construction elements, the Tamiya 70235 set fits universal plates, arms, and several gearbox types. It is handy for creating miniature forklifts, sliding gates, or compact push-pull linkages, and the included brackets and spacers make it easier to match different gearbox widths.
