Hydraulic cylinder HHD

pistondouble-actingsteel

Series HHD hydraulic actuators are suitable for applications requiring extra output power and durability to stand up to harsh conditions. They provide up to 3,000 psi of continuous force, making them ideal in high-pressure systems. And they’re also built to last. The cylinder barrel’s heavy wall is honed to an 8 to 16 µ finish to ensure piston bearing life, while the extra long rod cartridge is made of high-strength bronze to deliver exceptional bearing support and wear resistance. The cast iron pistons are designed to provide maximum strength and protection against shock loads Additional features include machined cushions to ensure gradual deceleration and reduced shock at the end of the stroke, Teflon® end seals, standard SAE ports and a circular rod bushing retainer so the rod cartridge can be removed without disassembling the cylinder. HHD hydraulic actuators are offered with 20 NFPA standard mounting options for interchange convenience. FEATURES • Circular rod bushing retainer to remove the rod cartridge without cylinder disassembly • Over 20 NFPA standard mounting options • Seven standard piston seal options • Four standard rod end seal options • SAE ports with 90-degree rotation standard • Pressure-energized nitrile U-cups with backup rings • Many standard options and configurations available
