  • Technical Data
    • Torque (T2max) Nm: up to 160.000
    • Transmission Ratio: up to 160 iN
    • Axial force: F = up to 2.000 kN

POSITWIN GL Double shaft extruder gear

  • Double shaft extruder gears have been built by P.I.V. since 1984 for a variety of applications in the plastics and food industries and have been put into operation around the world to our customers' complete satisfaction.
  • The gears are case hardened and ground and optimised with a profile correction according to the load, which consists of bending and torsion. A very good noise behaviour is achieved through a high contact ratio.
  • The axial forces which occur during extrusion from the process part are safely absorbed in the gear with tandem bearings and self-aligning roller thrust bearings.
  • This extremely compact and appealing design means that we are able to provide a modern, high-power gear in small installation spaces.
  • Technical Data
    • Screw centre distance: a = up to 200 mm
    • Input speed up to 1800 rpm
    • Torque factor: df = 35 N/mm2
