How do you specify a hydraulic cylinder

 Hydraulic cylinders are specified by the force required to be pushed and moved, and they are specified by their method of mounting. There are subordinate functions to be considered when specifying a hydraulic cylinder, such fluid type, column strength and material construction. However, 90% of cylinder applications are not exotic, and simply identifying force and mounting requirements will suffice, leaving all else standard. The first step in specifying a hydraulic cylinder is calculate the required force. Factors required to determine force are the mass of the load, direction of cylinder travel and angle of the force vector. The mass is easiest to know, in most cases. The direction of cylinder travel is also easy to determine; will the cylinder push or pull on the load? It is important to consider the difference because a cylinder pulls with less force than it pushes, due to the area taken up on the piston by the rod. The angle the cylinder pushes on the load at affects the force required, but because this part of the discussion requires trigonometry, I’ll leave it out for now. Let’s just say that if you’re not pushing at ninety degrees to the load, it requires more force.  Once the force requirement is defined, you will have to calculate the require bore of cylinder. The bore is inside diameter of the barrel, but also describes the outside diameter of the piston. The hydraulic fluid acts upon the piston, imparting force energy against it, and the larger the area of the piston or the higher the pressure you exert, the more force is generated
