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.
