The table below provides information on the most important parameters for conveyor design based on belt thickness, material quality and applied preload. Using the formula and belt below, preload, axle load and maximum transport weight can be quickly and easily determined.
Pretension force (N)
Table value x belt width used (mm)
Axe load (N)
Value from table x actual belt width used (mm) / number of axes (shafts)
Max.transport weight (kg)
Table value x belt width used (mm) x 0.05
For belt designs not listed, check the value of k1% on the corresponding data sheet and use the general formula on the next page to determine the required parameters.
Belt thickness mm : 1.0
Belt thickness mm : 1.2
Belt thickness mm : 1.6
Belt thickness mm : 1.8
Belt thickness mm : 2.0
Belt thickness mm : 3.0
Belt thickness mm : 4.0
General calculation formulas for belt design
Pretension force (N)
k1% (N/mm) x belt width (mm) x
pretension (%) x 2
Axe load (N)
k1% (N/mm) x belt width (mm) x
pretension (%) x 2 / number of axes
Max. transport weight (kg)
k1% (N/mm) x belt width (mm) x
pretension (%) x 0,1
