1. The table deflection forces and strand tensions are typically at maximum values to cover
the broad range of loads, rpm and pulley combinations for all possible drives.
2. For drives where hub loads are critical, high speed drives or other drives with special
circumstances, the belt deflection force and strand installation tension should be
calculated by using formulas found in existing engineering manuals or use the
MaximizerPro™ Drive Selection Analysis Program.
3. Consult the TensionRite® Belt Frequency Meter manual for detailed information on using
the frequency based tension gauge.
4. Continental ContiTech offers three different levels of tension gauges to aid you in
properly tensioning your power transmission belts. See your Sales Representative or
Distributor for more information on tensioning gauges.
