** Cylinder capacities are listed at 5,000 psi maximum operating pressure. Cylinder force can be adjusted by varying the hydraulic system pressure. To calculate the approximate output force for an application, multiply the predetermined operating pressure by the effective piston area. The actual output force will vary slightly due to frictional losses within the assembly.
