Bonfiglioli rectangular high-power gear motors

The HDO (HDx), 3/H, 3/A, 3/V lines were presented in the sector of rectangular planetary gear motors with increased power.

Bonfiglioli HDx Series

The devices can operate in the harshest conditions. And also where there is a high probability of an explosion. The output shaft is implemented in two options: parallel (HDP) and rectangular (HDO) configurations.

Key features:

  • High transfer power.
  • Strength.
  • Flexibility of installation.
  • Reliability.
  • Used where explosions are possible.
  • Temperature and oil level sensors.
  • Taconite seals.
  • Technical characteristics:
  • Torque range: 8,990 ... 209,000 Nm.
  • Gear ratios: 5.6 ... 490.
  • Spheroidal cast iron housing.
  • Line Connector 3/H

Bonfiglioli 3/H Series

The equipment of the series combines the high torque density of planetary gearboxes with the reliability and high speed of helical conical heavy-duty products.
