Hollow Plunger Cylinder, 326 kN, 178 mm Stroke - Enerpac RRH307

The RRH307 transmits 326 kN of push and pull force over a 178 mm stroke. Its through-hole hollow plunger allows pulling work with threaded rods, while the double-acting design retracts the plunger quickly.

Benefits

• Hollow plunger design for combined push and pull work
• Double-acting operation for fast plunger retraction
• Safety valve guards against damage from over-pressure
• Baked enamel finish for increased corrosion resistance
• CR400 couplers with dust caps fitted as standard
• Plunger wiper keeps out contamination and extends cylinder life
