Geared Motors with Rack and Pinion Drives

From high speed to high force, flange to shaft, STOBER has the options you need. Every rack and pinion system uses STOBER’s superior servo geared motors. These pinions work with a variety of rack options, including helical or straight tooth.

By combining them with our planetary or helical bevel gear units and STOBER servo motors, you get the benefit of extremely compact, highly dynamic drive solutions.

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_EZ series and works well for bridging larger distances between axes.

ZR units are available as compact servo or geared motors, or they can be mounted to any motor with our toleranced motor adapter.
