Helical gearboxes

The helical gearboxes of manufacturer Bonfiglioli Riduttori exclusively imported by ELSTO Drives & Controls covers three product groups;

C-series

The high torque ratio, and big variaty of versions and range of ratios, the compact dimensions and operational reliability are the key features to the success of the C-series and leading position in the inline gear unit market. Due to the various universal mounting positions and competitive pricing makes the C-series gearboxes favorite to many engineers and manufacturers.

  • Versions:
    • HS version with massive input shaft
    • P version with IEC or NEMA standardized motor flange
    • M version with integrated three-phase motor (optionally with brake)
    • SK version with servo motor flange
    • SC version with servo motor flange
  • Torque: up to 12,000Nm
  • Power: up to 213kW
  • Ratios: up to 1482
  • Mounting: foot, flange and universal housing

S-series

The S-series is lean, powerful and especially designed for driving pumps. For this reason the S-series gearbox is often used in cooling and drying towers, but also in other applications where pumps are needed.

The AS-series inline helical gear unit is the previous version of the current C-series helical gearboxes. The compact dimensions and modular configurations are core features resulting in the fact that this gear unit is still produced.

  • Versions:
    • HS version with massive input shaft
    • P version with IEC standardized motor flange
  • ​​​​​​​Torque: up to 480Nm
  • Power: up to 10.3kW
