Omex' DEX-Series Extruder Gearbox in double reduction parallel shaft horizontal and vertical models are intended to satisfy characteristic requirements and conditions encountered in single screw extrusion process. The gear unit are quite capable to transmit the high torque required for pressurizing and plasticising mauling materials. They can also absorb the high axial trust through built-in spherical roller thrust bearing. A separate critically designed axial bearing housing accommodate thrust bearing of different sizes according to application loads. The hollow output shaft mounted with the different thrust bearings have different bores to accommodate the thrust screw. The units can be offered in Left hand to Right hand configurations with horizontal and vertical mounting to meet specific mounting needs.
