Rack and Pinion Drives
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 gear units and can be made into a system with a motor. These pinions work with a variety of rack options, including helical or straight tooth.
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.
ZR units are available as compact servo or geared motors, or they can be mounted to any motor with our toleranced motor adapter.
