Geared Motors with Rack and Pinion Drives

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.

ZR EZ Series

For high speed applications

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.

Bearings: Standard ball bearing for some axial and radial load capacity; Reinforced bearing for high axial loads
Backlash: Standard, Reduced
Acceleration Feed Force: 2.1- 15 kN
Feed Velocity: .23 – 6.7 meters/second
Module: 2 – 4 mm
Number of teeth: 26 – 45
Backlash: 10 – 56 μm

ZTR EZ Series

For compact applications requiring high force

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.

Bearings: Standard ball bearing for some axial and radial load capacity; Reinforced bearing for high axial loads
Backlash: Standard, Reduced
Acceleration Feed Force: 2.1- 15 kN
Feed Velocity: .23 – 6.7 meters/second
Module: 2 – 4 mm

ZTRS EZ Series

For applications requiring extreme force

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.

Gear: Standard gear, Felt gear – simplify lubrication
Backlash: Standard, Reduced
Acceleration Feed Force: 16 – 126 kN
Feed Velocity: .06 – 4.7 meters/second
Module: 2 – 10 mm
Number of teeth: 15 – 32
Backlash: 7 – 70 μm

ZV EZSeries

For flexibility and economy

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.

Acceleration Feed Force: 16 – 126 kN
Feed Velocity: .06 – 4.7 meters/second
Module: 2 – 10 mm
Number of teeth: 15 – 32
Backlash: 7 – 70 μm
