Filing pressure-depending initial forces
The end forces are a maximum of 20% higher, depending on the pressure increase and/or the available volume.
a) Required filling pressure:
The required filling pressure is calculated as follows: Filling pressure = Requested force ÷ Piston active surface e.g. 3000 daN ÷ 22.8906 cm² = 131.05816 bar ~ 131 bar These examples are based on one cylinder each of the type ST 8841-1-025, ST 8841-2-025 or ST 8841-3-025
b) Calculating initial force:
The initial force is calculated by multiplying the piston active surface (22.8906 cm²) with the filling pressure. Initial force = Piston active surface x Filling pressure e.g. 22.8906 cm² x 120 bar = 2746.872 daN
