Rack & Pinion Drives
Rack & 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 gear units and can be made into system with a motor. These pinions work with a variety of rack options, including helical or straight tooth.
Industry Applications: Fuselage, Wing assembly, Drilling and Riveting, Machine Tool, Automated Guided Vehicles (AGV), Carbon Fiber Placement, Testing and Inspection, Space Tracking Systems
ZR 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 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. Bearings options for axial or radial loads: Standard ball bearing ideal for some axial and radial load capacity and Reinforced bearing ideal for high axial loads.
- Acceleration Feed Force: 5.8 – 67 kN
- Feed Velocity: .09 – 4.7 meters/second
- Module: 2 – 8 mm
- Number of teeth: 12 – 32
- Backlash: Standard and Reduced
- Backlash: 4 – 44 μm
- Find your right fit with Stober’s Configurator
ZTR 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 options for axial or radial loads: Standard ball bearing ideal for some axial and radial load capacity and Reinforced bearing ideal for high axial loads.
- Acceleration Feed Force: 5.8 – 67 kN
- Feed Velocity: .09 – 4.7 meters/second
- Module: 2 – 8 mm
- Number of teeth: 12 – 32
- Backlash: 4 – 44 μm
- Find your right fit with Stober’s Configurator
ZTRS 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 attached to the PH 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 and Felt gear – simplify lubrication
- Acceleration Feed Force: 16 – 126 kN
- Feed Velocity: .06 – 4.7 meters/second
- Module: 2 – 10 mm
- Number of teeth: 15 – 32
- Backlash: Standard and Reduced
- Backlash: 7 – 70 μm
- Find your right fit with Stober’s Configurator
ZV Series
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 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: 1.3 – 15 kN
- Feed Velocity: .06 – 5.3 meters/second
- Module: 2 – 4 mm
- Number of teeth: 16 – 25
- Backlash: 8 – 123 μm
