Tamiya 70235 Rack & Pinion Gear Set - Educational Builder  [70235]

Overview of Tamiya 70235 Rack & Pinion Gear Set

The Tamiya 70235 Rack & Pinion Gear Set is a practical part in the Educational Construction Series, well suited for hobbyists and teachers wanting to demonstrate fundamental mechanics. It converts rotational input into straight-line movement, making it an effective tool for teaching basic engineering and motion principles.

How the Rack and Pinion Operates

This kit contains two rack gears and two pinion gears so you can build assemblies that turn rotation into linear motion. The racks include 30mm holes to guide smooth sliding as the pinions turn. You can extend travel by removing the dividers between holes, and the pinions feature a clutch mechanism to protect gears and prevent damage during trials.

Fitment and Typical Uses

Made for flexible builds, the Tamiya 70235 set mates with many parts from the Tamiya Educational Construction Series, such as universal plates, arms, and gearboxes. Use it in projects like forklift mechanisms, compact bulldozer linkages, or sliding doors, with the supplied brackets and spacers helping adapt the racks to different gearbox sizes.
