GAM Rack & Pinion Systems

The GAM Helical Rack and Pinion series, along with our broad gearbox offering, provide a complete linear solution. Use our motion control engineering expertise to select the rack and pinion and match it with the right gearbox for your application.Rack and Pinion

Features

What is Rack & Pinion?

A linear actuator that converts the rotary motion of the (circular) pinion to linear motion at the (linear) rack.

Why use a Rack & Pinion System?

A rack and pinion system is the most cost-effective way for linear movements greather than 2 meters.

Why use a GAM Rack & Pinion System?

GAM matches the high quality rack and pinion with the best precision gearbox for optimized system performance. See our Rack & Pinion Systems.
