Enerpac CST18251 Portable Hydraulic Cylinder Single Acting

Product Description

The ENERPAC CST18251 is a single-acting portable hydraulic cylinder designed for controlled, high-force pushing applications in industrial and maintenance environments. Built on the CST series platform, it features a solid plunger design and a steel body construction for durability under repeated load cycles. The cylinder holds 0.78 cubic inches of oil and has a rod diameter of 1.22 inches. The lowered height is 3.52 inches and the maximum extended height is 4.50 inches, making it a compact option for tight-clearance work. A 5/16-24 internal thread on the plunger allows for attachment accessories when needed. Licensed mechanics, millwrights, and hydraulic technicians are the primary installers of this unit.

This cylinder is suited for light-duty portable hydraulic applications where a compact single-acting unit is required. The CST series is typically deployed in alignment, pressing, and positioning tasks across manufacturing, fabrication, and field service settings. Its small footprint and manageable weight of 1.2 pounds make it practical for handheld or low-clearance setups where a full-size cylinder would not fit.

Installation Notes

Installation should be performed by a qualified hydraulic technician or millwright familiar with hydraulic cylinder service procedures. Depressurize the hydraulic system completely and relieve all stored pressure before removing or installing any cylinder. Ensure hydraulic fluid compatibility and cleanliness to prevent seal damage or contamination. Follow applicable ASME and OSHA standards for hydraulic tooling and personal protective equipment during operation.
