Screw Conveyor Connecting Shafts

Our screw conveyor coupling shafts are precision manufactured from a select-grade of cold-rolled steel, these shafts are jig-drilled to assure an exact match with the jig-drilled conveyor pipe. For the higher demanding application and abrasive applications, we offer hardened steel screw conveyor shafts that are made with a tough ductile core and are case-hardened.

High-Torque Screw Conveyor Coupling Shafts

These special high-torque screw conveyor coupling shafts are jig-drilled for using three coupling bolts in the end of the conveyor pipe rather than just two. What this does is considerably increase the motor size and horsepower input ratings for the system, drive and tail coupling shafts are all jig-drilled to match the three bolt holes placed in the conveyor pipe.
