From high flexibility to high force: Rack and pinion gearboxes.

With the helical toothed ZV series of our rack and pinion gearboxes you can choose what you like – the pinion position is either at the shaft end or the shaft shoulder.

This series also has an impressive backlash-free, positive-locking shaft-hub connection.

ZV rack and pinion gearboxes can be attached to P, PE, K, KS or KL gearboxes.

The ZR series of Rack and pinion gearboxes features large, helical pinions with a bolt circle, which allow high feed velocities.

The pinions are mounted without an additional flange, which is one reason for the attractive price-performance ratio.

The very precise and also very high-performance ZTR series features small pinion diameters, high linear rigidity and lower torques.

The pinions with the welded screw flange can be easily mounted and dismounted. The ZTR series is therefore ideal for feed axes of machine tools where the supporting bearing holder is an interfering contour. This means gantry machines, vertical and horizontal lathes or milling and drilling centers.

The rack and pinion gearboxes can be combined with PH and PHV series gearboxes.

Developed by STOBER, the bolted supporting bearing holder with stiffening ribs on the inner contour makes it possible to use the full gearbox torque in a rack and pinion drive for the first time. As a result, this also optimizes the power density and rigidity. To determine the drive, the relevant variable is no longer the tilting torque, but the torque that is actually required.

The rack and pinion gearboxes of the ZTRS series is ideal for feed axes of machine tools, laser machines and highly dynamic and precise handling systems. The rack and pinion gearboxes can be combined with the PH, PHQ and PHV series gearboxes.

STOBER offers precision gear racks in various lengths to ensure that you find the perfect solution for every design task – to create individual, custom-fit solutions.

• 0.5 meters and 1 meter – with double the number of bores
  Twice the number of bores with a spacing of just 62.5 millimeters ensures increased contact pressure and generally eliminates the need for pinning. However, if required, this option is still available. If every second bore is used, the gear racks are fully compatible with standard commercially available systems.
• 2 meters – for long travel paths
  Perfect when it comes to efficiency and precision over long distances: fewer mounting points, minimal impact points and reduced pitch deviations. As usual, it is reliably fastened by the screws, while pinning is still possible as an option.
