FLENDER Gear Units for Double Screw Extruders (Co-Rotating)

Description

To absorb the very high torque and axial forces from the extrusion process, we have developed an extruder gear unit with double load sharing system and special thrust bearings. The bearing assembly can consist of up to eight thrust bearings in a row. Output torques from 200 to 35,000 Nm and center distances between 18.3 and 140 mm can be achieved. In addition, we can also provide customized solutions up to 20,000 kW.

Advantages

  • Gear unit with highest power capacity

  • Short delivery time due to consistent standardization of housings and internal components

  • Center distances can be changed rapidly with minimal design effort


Applications

FLENDER double screw extruder gear units with parallel output shafts and unidirectional screw rotation are mainly used in pellet production and processing of raw plastics. Further applications include:

  • Paint and varnish industry

  • Detergent industry

  • Food processing industry (such as bread, pasta)

  • Animal feed industry (for dogs, cats, pets)
