Rack and Pinion Drive Systems
From high speed to high force, flange to shaft, STOBER has the options you need, especially when it comes to rack and pinion drives. Every rack and pinion system uses STOBER’s superior servo gearboxes and can be made into a system with a motor. The versatility of our rack and pinion drive systems makes them indispensable across a broad spectrum of industries. Examples of our products can be found in the packaging, beverage, food processing, automotive, printing, and material handling sectors, among others. All of our rack and pinion drive systems are available as compact servo or geared motors, adding to their adaptability. Additionally, they can be mounted to any motor featuring our tolerance motor adapter. If our standard systems don’t fit exactly into a customer’s existing setup, we also have the capability to design customized solutions that will.
The ZR series is ideal for high-speed applications. The large helical pinion mates to the rack for high feed rates. It is attached to the PH series and works well for bridging larger distances between axes. The ZR pinion works with the STOBER precision helical rack, available in ½-meter, 1-meter, or 2-meter lengths.
ZR gearboxes are available as compact servo or geared motors, or they can be mounted to any motor with our toleranced motor adapter.
