• RMK – pinion mounted on keyed shaft

  • 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 and 100% tested pinions eliminate potential sources of error.

Linear system rigidity

Highest linear rigidity due to direct connection of pinions with small pitch circle diameter.

Positioning accuracy

The marked high point allows perfect adjustment of the gear backlash between the pinion and rack.
