Highest torques, efficiency and reliability are the main characteristics of our POSITWIN series of twin-screw extruder drives. This series reaches a torque factor up to 20 per shaft. The case hardened gears are ground and optimized with a profile correction based on its bending and torsion load. The high gear contact ratio ensures a low noise level in these gearboxes. Axial forces generated by the machine during extrusion are absorbed in the gear by tandem bearings and self-aligning roller thrust bearings. More than 7.000 Brevini PIV twin screw extruders have been produced since 1985 and prove their reliability and performance day by day, installed at the leading companies in the plastics, rubber, pharmaceutical and food industries.
