Choice of belts and pulleys

2.Choice of belts and pulleys

(1)Choice of belt thickness

  • Power transmission belt: Thickness 0.04 to 0.1mm, Width 10 to 40mm
  • Conveyor belt for light-weight workpieces: Thickness 0.08 to 0.2mm, Width 10 to 50mm
  • Conveyor belt for light-weight workpieces: Thickness 0.1 to 0.5mm, Width 10 to 500mm
  • Conveyor belt for heavy-weight workpieces: Thickness 0.6 to 1.2mm, Width 200 to 1500mm

(2)Choice of pulley diameter

  • Pulley Diameter for DR type belts =Belt thickness (t) X 400 or more
  • Pulley Diameter for DW type belts =Belt thickness (t) X 700 or more

In power transmission choice of pulley diameter is;

  • Pulley Diameter for DR and DO type belts = Belt thickness (t) X 400 or more

Please fill in questionnaire for belt stress calculation in power transmission and conveyors.


(3)Edge positioning

(1)Crown pulley

Crown pulley prevents belt wandering.
