* Tension values for these pulleys must be calculated.
Tension gauges:
Optikrik 0 Range: 70 – 150 N
Optikrik I Range: 150 – 600 N
Optikrik II Range: 500 – 1400 N
Optikrik III Range: 1300 – 3100 N
Procedure
1. Look for the applied section in the column.
2. For this purpose take the smallest pulley diameter in the
drive system.
3. You can read the corresponding static tension from the table.
4. Check static tension with the tension gauge as described.

The tension values (static belt tension) shown are guideline
values when accurate drive data is not available. They are
calculated for maximum power transmission capability per belt.
Calculation Basis
Wedge belts belt speed v = 5 bis 42 m/s
Classical V-belts belt speed v = 5 bis 30 m/s
Operation
after
start-up
Example
1. Optibelt V-belt standard section SPZ
2. Smallest pulley diameter in drive 100 mm
3. Static belt tension – tension initial installation 350 N
4. Static belt tension – tension in operation 250 N
