*All recommended preload values are calculated based on the needs of the seal. If the bolt is also subjected to a large joint load, or because the tension or deflection force of the bolt is greatly increased due to the thermal expansion and contraction of the connected equipment, the actual preload load needs to be taken into account and select a larger load disc spring, but should not exceed the Maximum Preload of Bolt in the table.
