• Rack and pinion drives

Innovative design rack and pinion drives with supporting bearing cover permanently bolted in place.
For applications in machine manufacture, automation and robotics.

STÖBER ZV rack and pinion drive

Compact systems with pinion directly mounted on the gearbox for rack and pinion drives. Suitable for robots and handlingsystems.
For gear units in the Stöber series: PE / P / PA / PK / PKX / PE / KS / K / KL, modules 2, 3 and 4 with spur and spiral toothing.
Force: 5 – 17 kN.

Zero backlash shaft hub connection (shrink glued and connected via feather key).

STÖBER ZR gear rack drive

The new ZTR design gear rack drive with supporting bearing cover permanently bolted in place makes it possible to fully utilize the gearunit's torque. As a consequence smaller gear units and smaller motors can be used.

Innovative system concept for gear rack drives in machine tool manufacture.

On conventional gear rack drives (with-out supporting bearing) the gear unit bearing is the limiting element and as a result defines a gear unit size that is often over-dimensioned for the actual torque required.
