Graphs are calculated using theoretical pressures and
actual values will be less due to loss in system pressure.
TECHNICAL INFORMATION -
Max Operating Pressure =
350 BAR (5000 P.S.I)
Theoretical Thrust (N) =
Oil Pressure (bar) x Effective Area (Full
Bore Side) (cm²)
Theoretical Pull (N) =
Oil Pressure (bar) x Effective Area
(Annulus Side) (cm²)
