High End

The high-end range includes the gearbox lines GSD (flange gear), GSB (inline) and GSBL (angle gear). All three lines are equipped with precision ground helical gearing, single-piece planetary carriers and full needle bearings. The housings are designed from a one-piece, robust housing. This improves the gear rigidity and enables the absorption of higher loads. The sun pinions are fitted with an additional bearing system in order to ensure quieter operating behavior. The 2-stage versions are constructed in a space-optimized design. Due to the lower torque values, the input stage is dimensionally smaller than the output stage.

GSD

  • Compact design
  • Highest torsional rigidity
  • High permissable radial & axial force

GSB

  • Low backlash for high precision, standard up to <=3 arcmin, optional up to <= 1arcmin
  • High torque level
  • Best corrosion protection for complete housing including output side

GSBL

  • Right angle version for space restricted applications
  • High torque level
  • Up to ratio 200 in 2-stage version

High End Economy

The high-end economy lines GSN and GFE are equipped with ground, helical-cut precision components, which ensure low operating noise, very quiet operating characteristics and above-average torque absorption. Both lines have a full needle bearing, which has been especially designed for high torques. The planetary carriers are manufactured as a cage made from solid material. This increases quiet operating characteristics while at the same time improving positioning accuracy and reducing backlash.

GSN

  • Low noise level due to ground helical gearing
  • High power density
  • Protection class IP65

GFE

  • Big housing sizes up to 220 mm
  • Max. input speed up to 10,000 rpm
  • 30,000 h life time
