Pinions

  • RMF – pinion mounted on flange

  • RMW – pinion mounted on system output

  • RMS – pinion mounted on splined shaft (DIN 5480)

A pinion perfectly suited for any application

Our preferred linear systems already offer the ideal pre-selection of pinions in terms of smooth running, positioning accuracy and feed force – matched with the gearbox and rack. Furthermore, an additional wide selection of different variants are available. cymex® 5 gives you the option of selecting the perfect pinion.

  • Factory-assembled
  • Value Class pinion
  • Standard Class RSP pinion
  • Premium Class RTP pinion
  • Premium Class+ and High Performance pinion

All of our pinions are supplied factory-assembled.

This offers you the following benefits:

  • Verified quality thanks to a comprehensive final inspection
  • Maximum quality and reliability, perfect gear backlash adjustment between rack and pinion thanks to aligned pinion and marked peak*
  • Elimination of potential sources of faults in your assembly

* Not for Value Class pinions

Product features:

  • Precision gearing with optimally designed tooth geometry
  • Low backlash shrink-fit/bonded connection with key for overload protection
  • Factory shrink-fit/bonded connection guarantees perfect positioning of the pinion throughout its service life.


In addition to our helical pinion for our rack and pinion system, these pinions are also available in straight gearing, e.g. as a slewing ring drive.

Product features:

  • Precision gearing with optimally designed tooth geometry
  • Positive involute connection between pinion and gearbox
  • Compact design
  • Factory-assembled with marked peak


In addition to our helical pinion for our rack and pinion system, these pinions are also available in straight gearing, e.g. as a slewing ring drive.

Product features:

  • Highly precise and optimally designed tooth geometries for the best possible power transmission, extremely smooth running and precision in the application
  • Adapted to standard gearbox series with the tried and tested TP+ output flange
  • High feed speed at low input RPMs thanks to large pitch diameter
  • Compact pinion/gearbox connection
  • Factory-assembled with marked peak


In addition to our helical pinion for our rack and pinion system, these pinions are also available in straight gearing, e.g. as a slewing ring drive.

Product features:

  • Highly precise and optimally designed tooth geometries for the best possible power transmission, extremely smooth running and precision in the application
  • Innovative pinion/gearbox connection offers:
  • Maximum linear rigidity thanks to direct connection of pinions of small pitch diameters
  • Maximum flexibility in pinion selection
  • Optimally dimensioned and rigid pinion/gearbox connection
  • Compact drive design
  • Factory-assembled with marked peak
