ALUMINUM SINGLE ACTING CYLINDER MODEL: ZR-504A - 50 TON 4" STROKE

The Zinko ZR-504A Aluminum Hydraulic Cylinder ups the ante in our 50-ton class by offering a versatile 4.25" stroke. Stepping up to an extended height of 13.22" from a 9.29" collapsed stance, this 29-pound unit remains remarkably easy to transport across the job site. It is constructed from our strongest heat-treated aluminum alloys to deliver severe-duty performance without heavy steel weight. Like the other 50-ton models, it supports an optional aluminum base for enhanced stability in unstable environments and connects to any 10,000 psi air-over-hydraulic pump. A steel base plate, grooved saddle, and fast-flow quick-connection couplers come standard.

 Features: 

• These cylinders are suitable for almost every heavy lifting situation, in the shop or on the job site. Easily carried around and easy to connect with any 10,000 psi air over hydraulic pump.
• All models com with 3/8" NPT fast flow quick-connection coupler and dust cap.
• Made of the strongest aluminum alloys and heat-treated to provide a maximum combination of strength and fracture resistance.
• Optional valve to control cylinder speed - can also be used as shut off valve for temporary load holding.
