Tamiya 70235 Rack & Pinion Gear Set - Classroom and Hobby  [70235]

Introduction to the Tamiya 70235 Rack & Pinion Gear Set

The Tamiya 70235 Rack & Pinion Gear Set is a robust teaching aid in the Educational Construction Series, suitable for model builders and educators demonstrating motion systems. It translates rotary movement into straight-line travel to illustrate mechanical principles clearly.

Design Notes and Operation

This kit includes two rack gears and two pinion gears so you can assemble mechanisms that convert rotary input into linear output. The racks are drilled with 30mm holes to allow controlled sliding while the pinions engage. You can remove dividers between holes to lengthen travel, and the pinion clutch reduces the chance of damage during testing.

Where to Use It

Built for compatibility, the Tamiya 70235 set fits with many items from the Tamiya Educational Construction Series such as universal plates, arms and gearboxes. It is suited to applications like fork lift models, sliding door mechanisms and other linear motion assemblies, with brackets and spacers included to match different gearbox arrangements.
