Tamiya 70235 Rack & Pinion Gear Set - STEM Component  [70235]

About the Tamiya 70235 Rack & Pinion Gear Set

The Tamiya 70235 Rack & Pinion Gear Set forms a practical teaching and hobby accessory within the Educational Construction Series, useful for demonstrating mechanical movement. It turns rotational force into direct linear action, making motion concepts easy to visualise.

Construction and Operation

The package contains two rack and two pinion gears to build mechanisms that convert rotation to linear travel. Racks are provided with 30mm holes which aid smooth sliding while the pinions rotate. To increase the travel distance you can remove the dividers between holes, and the pinions incorporate a clutch to minimise risk of damage from overload.

Compatibility and Typical Builds

Compatible with an array of Tamiya Educational Construction parts, the Tamiya 70235 set connects to universal plates, arms and several gearbox styles. Typical uses include small forklifts, sliding doors and simple drivetrain prototypes, while included brackets and spacers help fit the racks to various gearbox widths.
