Cantilevered Screw Conveyors - Thomas and Muller Systems

A cantilevered screw is usually a short screw since in its design the deflection of the screw is always calculated to insure that the screw does not rub on the housing when running. The drive shaft of a cantilevered screw is always supported by two bearings with the screw projecting out from the shaft inside the housing, to the end discharge.

Ball Screw: What Is It? How Does It Work? Lead Screws

Lead. Lead is the linear distance along the axis of the screw that is covered by one complete rotation (3600) of the screw. It is an important specification of a ball screw which determines linear travel and speed and load capacity. As the lead of ball screws increases, the linear distance covered and the speed increase.
