CE Large Capacity 2M Shaftless Screw Conveyor

CE Certification Stainless Steel Helical Blade Shaftless Spirals Centerless Screw Flighting

Shaftless flight is a heavier helix flight with an open center in the outer diameter and pitch. This product works well when moving sticky products and large pieces. Shaftless threads are usually located inside the groove and are driven from one end by a flange or stub shaft. The other end may be open, or it may be connected to a stub shaft or mounting flange. Advantages include no need for intermediate bearings, no central tube, reduced maintenance costs, extended service life and increased screw capacity.

Shaftless Flight Technical

Shaftless Flight Features

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).

Double flight
The description standard of single helix (double helix) with insert is as follows:
Outer diameter (OD)
Pitch (linear distance between two flights)
Bar size (if known).
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 inserts (second spiral)
