Product catalog summary
Overview: The document provides technical specifications and features of the RARH-Series Hollow Plunger Cylinders by Enerpac. These cylinders are designed for double-acting applications, offering a lightweight solution with various capacities and strokes.
Key Features:
  • Lighter and shorter collapsed height compared to RACH single-acting models.
  • Double-acting design for rapid retraction, independent of hose lengths or system losses.
  • Built-in safety valve to prevent over-pressurization.
  • Hollow plunger design allows for both pull and push forces.
  • Composite bearings enhance cylinder life and resistance to side loads.
  • Hard coat finish on all surfaces for damage resistance and extended life.
  • Handles included on all models for ease of use.
  • Floating center tube increases seal life.
  • Steel baseplate and saddle protect against load-induced damage.
  • Integral stop ring prevents plunger over-travel and withstands full cylinder capacity.
  • Compliance with ASME B-30.1 standards.
Specifications:
  • Capacity: 30 - 150 tons.
  • Stroke: 2-10 inches.
  • Maximum Operating Pressure: 10,150 psi.
  • Center Hole Diameter: 1.34 - 3.11 inches.
Additional Components:
  • Gauges: Minimize risk of overloading and ensure dependable service.
  • 4-Way Control Valve: Available in P-84 and P-464 pumps for use with double-acting or single-acting cylinders.
  • Hoses: Enerpac offers a complete line of high-quality hydraulic hoses to maintain system integrity.
Installation and Usage Notes:
  • Steel base plate should not be removed as it protects the cylinder base from damage.
