• Capacities from 55 to 573 tons.
• Stroke lengths from 1.77 to 2.01 inches.
• Working pressure 10,000 psi.

Single acting, load return. Mechanical lock ring feature allows for load holding for extended periods. Compact, low height design suitable for vertical lifting applications only. Threaded piston with tilting saddle fitted as standard to reduce the risk of side loading. Nitrocarburized cylinder body and piston rod for increased corrosion protection. Low friction bearing surfaces. Anti-extrusion seals for improved performance at high pressures. Overstroke restrictor port to prevent over extension of piston. Tommy bars for easy rotation of the load holding lock ring are listed in the below table. Customized and special design cylinders are available on request.

If specifying this cylinder for use with the SLF and SLV synchronous lifting systems and associated mounting kit, please consider the increase in dimension A (closed height).
