55 Ton High-Pressure Hydraulic Cylinder, Single Acting, 4″ Stroke, General Purpose

55 Ton High-Pressure Single Acting General Purpose Hydraulic Cylinder – 4″ Stroke

Engineered for serious power and precision, the PowerX C55-4 55 Ton, 4″ Stroke High-Pressure Single Acting General Purpose Hydraulic Cylinder delivers an impressive 55 tons of force at 10,000 PSI. This single-acting high-pressure hydraulic ram is built to bend, push, lift, and hold heavy loads with smooth, controlled performance, ideal for demanding industrial, construction, and maintenance applications.

Constructed from heavy-duty steel with a precision chrome-plated plunger, the C55-4 hydraulic ram is designed for continuous use under extreme conditions. Its spring return design ensures fast retraction, while roll-burnished cylinder walls reduce wear and extend seal life for long-term reliability. Equipped with collar threads, base mounting holes, and a 3/8” NPTF high-flow coupler with dust caps, this high-pressure hydraulic jack is field-ready and ANSI B30.1 compliant.

Perfect for shipyards, steel mills, mining operations, construction projects, and heavy-equipment maintenance, the PowerX C55-4 delivers unmatched strength, safety, and performance when every lift counts.
