Quick drive guide for Belt calculations
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, the preload, axle load and maximum conveying weight can be determined quickly and easily.
Pretensioning force (N)
Table value x width of belt used (mm)
Shaft load (N)
Value taken from table x actual width of belt used (mm) / number of axles (shafts)
Maximum transport weight (kg)
Table value x width of belt used (mm) x 0.05
For Belt models not listed, check the k1% value on the corresponding data sheet and use the general formula at the bottom of the page to determine the required parameters.
Belt thickness (in mm): 1.0
Belt thickness (in mm): 1.2
Belt thickness (in mm) : 1.6
Belt thickness (in mm) : 1.8
Belt thickness (in mm) : 2.0
Belt thickness (in mm) : 3.0
Belt thickness (in mm) : 4.0
General calculation formulae for Belt design
Pre-tension force (N)
k1% (N/mm) x belt width (mm) x pretension (%) x 2
Axle load (N)
k1% (N/mm) x belt width (mm) x pre-tension (%) x 2 / number of axles
Max. transport weight (kg)
k1% (N/mm) x belt width (mm) x pre-tension (%) x 0.1
