Standard camber and shape of drums and pulleys for Conveyor Belts and Flat belts

Courroies à assemblage rapide ERO Joint

Tapered roller shape for Conveyor Belt guidance

Forme des rouleaux coniques pour le guidage des bandes transporteuses

b = drum width

bc = width of cylindrical part

bo = belt width

h = taper

Calculation of the cylindrical part in relation to the total width of the drum:
bc = bo / 2

Calculation of drum width :
b = bo x 1.1

Calculation of taper :
h = (d + 100) / 450 mm
