CRESCENT Extruder Gearboxes having hardened and ground gears in double reduction, parallel shafts, horizontal models are intended to satisfy characteristic requirements and condition commonly encountered in single screw extrusion process. The gear units are quite capable to transmit the high torque required for pressuring and plasticizing moulding materials and also to absorb the high axial thrust loads through built-in spherical roller thrust bearing. The axial bearing housing integral with the main case is standardized to accommodate suitable thrust bearing and corresponding output shafts.

All the components of gearboxes undergo a very strict quality control check at different stages of production. Finish product are finally tested to ensure that no scope is left for complains about noise, oil leakage, temperature rise, etc.

NOTE - This catalogue contains specifications, dimensions, and ratings for selection of standard extruder gear drives against usual screw sizes/extrusion plants. However, mounting flange and output shaft version maybe customized to suit any special extruder and screw shaft requirements.
