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.

BENEFITS
The World’s Toughest Gearboxes
STOBER’s unique line of rack and pinion systems can handle a variety of machine needs, from high force to high speed.

Improve your machine’s repeatability with high stiffness.

The rack and pinion offerings can be mated to both flange geared motors as well as shafted inline or right angle options. Selection and calculations are done by STOBER for a completely engineered solution.
KSS: For the toughest environments
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.
K/KL: For right angle applications
The ZTR series is perfect for applications that require high force but have smaller machine envelopes. It attaches to the PH series and works well for machine tool feed axes. ZTR gear units are available as compact servo or geared motors, or they can be mounted to any motor with our toleranced motor adapter.
KSS: For the toughest environments
The ZTRS series is perfect for applications that require high force. It allows the machine to have optimal performance and stiffness. The bearing cover and felt gear provide additional force. It is attached to the PH_EZ series and works well for machine tool feed axes. ZTRS gear units are available as compact servo or geared motors, or they can be mounted to any motor with our toleranced motor adapter.
KSS: For the toughest environments
The ZV series can be paired with numerous STOBER gearboxes, giving you the freedom to have an inline or a right angle solution. It is ideal for general automation applications and offers great performance. It attaches to the P, PE, KS, K, and KL geared motor series. ZV gear units are available as compact servo or geared motors, or they can be mounted to any motor with our toleranced motor adapter.
