General Purpose Hydraulic Cylinder, 32.5 Tons Capacity, 8.25" Stroke
Enerpac RR308 is a Baked enamel finish for increased corrosion resistance with Removable hardened saddles to protect the plunger during lifting and pressing. It comes with a built-in safety valve that prevents accidental over-pressurization. Its Collar threads, plunger threads and base mounting holes for easy fixturing. Also, the Plunger wiper reduces contamination, extending cylinder life and CR400 is included on all models.
Think Safety
Manufacturers’ rating of load and stroke are maximum safe limits. Good practice encourages using only 80% of these ratings!
Pump Selection
A double-acting cylinder must be powered by a pump with a 4-way valve.
