Check the diagonal dimensions (between the axles of the drum motor and the axles of the
end/guide rollers or from belt edge to belt edge).
The difference must not be greater than 0.5 %.
The idler pulley should be cylindrical since a camber in the idler pulley could work against the
camber in the drum motor, thereby causing a belt migration.
Diagonal check
The distance between the belt and the gliding plate must not exceed 3 mm.
0-3 mm

The required belt tension depends on the respective application. The pertinent information is

Do not tension the belt beyond the value recommended by the manufacturer or specified in
the product tables of the catalog.

Link belts, steel belts, Teflon-coated fiberglass belts and hot-formed PU belts should not be
tensioned (see the instructions from the belt manufacturer).

Adjust the belt tension by tightening or loosening the corresponding screws on both sides of
the conveyor to ensure that the drum motor is positioned at a right angle to the conveyor
frame and parallel to the end roller/idler pulley.
