Extruder Gearbox

Extruder Gearbox

General  Description

‘Premium’ GHE-Series Extruder Gearboxes 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 units are quite capable to transmit the high torque required for pressurising and plasticising moulding materials. They can also absorb the high axial thrust through built-in spherical roller thrust bearing. A separate critically designed axial bearing housing accommodate thrust bearings of different sizes according to application loads. The hollow output shafts mounted with the different thrust bearings have different bores to accommodate the thrust screw. The units can be offered in Left hand or Right hand configurations with horizontal and vertical  mounting to meet specific mounting needs. The modular design of GHE Series gearboxes offer a great range of flexibility in the interchangeability of parts.
