Double Acting Hollow Plunger Hydraulic Jack

Hollow Plunger Hydraulic Cylinder (also known as center-hole cylinder) provides a versatile solution for tensioning, testing, pulling and lifting. A Hydraulic Cylinder with a hollow plunger allows for both pull and push forces. Choose between single-acting and double-acting models, and cylinder bodies constructed in either high-alloy steel or anodized aluminum. 

DY-RRH Series Hollow Hydraulic Cylinders are double-acting for a faster and more controlled plunger return. They’re constructed from steel and finished with a baked enamel exterior coating. Collar threads and base holes are provided as standard for easy fixturing.  

DY-RRH Series Hollow Plunger Hydraulic Cylinders are ideal for tensioning, testing, pulling, and lifting applications. The hollow bore, base threaded holes and collar thread allow attachments that enable the cylinder to deliver both pull and push forces.

DY-RRH Series double-acting center-hole hydraulic cylinders feature two connection ports to provide hydraulic flow to both advance and retract the plunger. This provides a more controlled retraction than single-acting cylinders.

Cylinders in the RRH-Series are constructed from high-alloy steel and finished with a baked enamel exterior coating. Collar threads and base holes for easy fixturing are provided as standard. This cylinder can used with our double acting Hydraulic Pump (both double acting Air Hydraulic Pump and Electric Hydraulic Pump) to lift heavy equipment.
