* Cylinder capacities are listed at 5,000 psi maximum operating pressure. The output force is adjustable by varying the hydraulic system pressure. To determine approximate output force for your application, multiply the piston area by the operating pressure. Actual force may vary slightly due to friction loss, seal and wiper drag and/or return springs. ** Cylinder stroke may exceed stroke of the clamping element. Limiting cylinder stroke may be required to ensure proper operation of clamping element. *** At full cylinder capacity, fastener life will be limited, should be considered service item and replaced frequently to avoid plunger damage. Models 21-4106-00, 21-4109-00, 21-4111-00 and 21-4113-00 not recommended for use above 2,500 psi.
