Enerpac's RC and RR-Series hydraulic cylinders are industry-standard components for high-pressure hydraulic applications. These cylinders boast robust steel construction with a baked enamel finish, ensuring durability. Compliant with ASME B30.1 (except BRD-RD-Series), they are known for reliability. Center hole cylinders, available in single and double acting styles, facilitate pushing and pulling applications. With a center tube for rod or cable passage, they are operated similarly to standard counterparts, with single acting cylinders featuring a spring for retraction, and double acting cylinders requiring a 4-way valve.
Center hole jacks and cylinders are available in both single and double acting styles. These cylinders are primarily used for pushing and pulling applications. Both styles have a center tube that allows a rod or cable to pass through the cylinder and assist in tensioning / pulling applications.
Both single acting and double acting center-hole cylinders are constructed and operated in a similar manner to their standard counterparts. Single acting center-hole cylinders utilize a spring for retraction. This cylinder type requires a pump source with a 3 way valve for proper operation.
Double acting center-hole cylinders are hydraulically extended and retracted.This cylinder type requires a pump source with a 4 way valve for proper operation.
