Basic Conveyor Flight & Pitch Types - Kase Conveyors. Standard Pitch, Single Flight. Conveyor screws with pitch equal to screw diameter are considered standard.

Screw conveyor capacity is affected when the flight pitch is reduced from standard full pitch. Reducing the flight pitch reduces the capacity. For example, a 1/2 pitch screw carries 1/2 the capacity of a full pitch screw at the same level of trough loading and speed.
