C Series General Purpose Single-Acting Cylinder, 55 Ton, Inch Rod, Inch Stroke

Description & Features

Rated at 55 tons and built to ASME B30.1 standards at 10,000 PSI, the C Series General Purpose Single-Acting Cylinder is a solid-steel, general-purpose hydraulic cylinder suited for lifting and pressing applications across industrial environments. With a cylinder effective area of 11.04 sq in and an extended height of 17.375 inches, it delivers consistent, high-force output in a compact profile.

The chrome-plated piston rod resists wear and corrosion, while an aluminum bronze bearing reduces the effects of off-center loading. Maximum-sized return springs speed piston retraction and extend spring service life. Base mounting holes are standard on this model, and a 3/8" NPTF female half coupler is included. A wide range of accessories can be threaded onto the piston rod, collar, or cylinder base, providing flexibility across different tooling setups.
