RRH-Series Double-Acting, Hollow Plunger Cylinders

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.

RRH 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.
