SGS Continuous Centerless Shaftless Screw Conveyor

SGS Continuous Flight Auger Long Pitch Shaftless Screw Blade Centerless Screw

Single flight
Use the following conditions to describe a single spiral (without blade):
Outer diameter (OD)
Spacing (the distance between adjacent flights). Many manufacturers only provide a pitch equal to the diameter.
Rebar size (if known). The size of the rod determines the inner diameter.
The spiral is usually manufactured in a right-handed configuration, but it can also be manufactured in a left-handed configuration. The spiral can be used in push, pull or reverse mode. Depending on the design and application, the spiral can be with or without an insert (second spiral).
