Enerpac SURS51 Portable Hydraulic Cylinder 25 Cu in

Product Description

The ENERPAC SURS51 is a portable hydraulic cylinder designed for single-acting lifting and pushing applications in industrial and mechanical service environments. With an oil capacity of 25 cubic inches and a rod diameter of 0.63 inches, it delivers controlled hydraulic force in a compact, field-ready package. The lowered height of 2.6 inches allows it to fit into tight clearances, making it practical for machinery maintenance, equipment alignment, and shop press work. Licensed mechanics, millwrights, and hydraulic service technicians are the primary installers and operators of this unit.

The SURS51 is suited for portable hydraulic service tasks where a low-profile cylinder with a threaded plunger is required. The internal plunger thread size of 5/16-18 with a thread length of 0.75 inches allows attachment of pull adapters or threaded tooling, expanding its utility across a range of push-pull service setups. It is appropriate for light-duty industrial maintenance, equipment repair, and controlled-force applications in both shop and field settings.

Installation Notes

Installation and operation should be performed by a qualified mechanic or hydraulic technician familiar with hydraulic system safety practices. Relieve all system pressure and depressurize the hydraulic circuit before connecting or disconnecting the cylinder. Inspect all hydraulic fittings and hose connections for leaks before applying load. Do not exceed the rated capacity of the cylinder or use it in applications involving shock loading.
