C556C 55 ton, Single-Acting Spring-Return, Hydraulic Cylinder with a 6.25 inch Stroke.

The Power Team C556C is a 55-ton, single-acting hydraulic cylinder with a 6.25 inch stroke, engineered for high-force applications requiring compact form and reliable spring return. Operating at a maximum pressure of 9,959 psi, it delivers 11.04 in² of effective area and holds 69 in³ of hydraulic oil. The cylinder stands 11.13 inches retracted and 17.37 inches extended, with a 5-inch outer diameter and 3.75-inch mounting hole.

Built from high-strength steel, the C556C features a chrome-plated piston rod for corrosion resistance and an aluminum bronze bearing to minimize wear from off-center loads. Collar threads (1/2-13) simplify fixturing, while oversized return springs accelerate retraction and extend service life. A 3/8 in NPTF female half coupler is standard, and removable rubber boots protect the collar threads during transport. This model is optimized for lifting, pressing, and maintenance tasks in industrial environments where durability and precision are critical.
