Click to chat· Pressure intensification. The equation F = p x A can be transposed as p = F/A that is pressure equals force divided by area. If the rod side of the cylinder has to resist the force developed by the piston side with only half the area then it needs double the pressure. This means that if the piston side is pressurized to 3 000 PSI a pressure

To build cylinders with higher pressure rating or larger bore a
Click to chat· On welded cylinders it is welded to the hydraulic cylinder tube so no seal is required. Some cylinders are made single-acting (push under pressure gravity return) but most are double-acting which means that the piston is under pressure on both the push and pull side of the cycle. Double-acting cylinders can be easily used in single-acting
Click to chat· Hydraulic cylinders are designed to apply force along a specifically intended axis that is aligned with the cylinder itself.
