Ask A Question

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.

got a small press setup, how much stroke does this cylinder actually have?
Answer by: Customer Support on Feb 19, 2026, 7:47 PM
Capacity and pressure are spelled out at 55 tons at 10,000 PSI, plus an 11.04 sq in effective area and a 17.375 in extended height. The stroke length is not provided in the details given, so it cannot be confirmed from the available product information.

Reckon this cylinder would be alright for straightening out some metal pieces in my shop?
Answer by: Customer Support on Mar 2, 2026, 6:55 AM
This cylinder is a solid choice for pressing applications. With its 55-ton capacity and durable steel construction, it should provide the force you need for straightening metal.
