Gearbox for Co-rotating Parallel Twin Screw Extruders

【SLTW , SLTWH, TWT Series】 Corresponding to the increasing demand of the twin-screw extruder, Sun Lung had developed the series of high torque gearboxes for the co-rotating twin-screw extruders. The gearboxes are embedded with excellence heat dissipation and oil lubrication system to perform stable output capacity under heavy-loading force. The construction of this gearbox is composed of the primary reducing section and the distribution section, which are combined by a trusting bearing housing and a pressure flange that absorb the axial loading from the extruder. The gearbox of this series have the compact construction、low noise、heavy loading capacity and high production output.


  • Featuring high torque and high output speed rate design
  • Excellent Mixing and Plasticizing performance
  • Coupled with thrust bearings assembled in multi-row tandem package
  • The best transmission efficiency & high torque and sufficient safety coefficient
  • The precision of gear grinding up to DIN 1~3 grade, operation noise is kept below 70dB
  • Forced lubrication and built-in the cooling & filter system ensures excellent heat dissipation
  • Solid gearbox structure strength ensures minimum rotation vibration
