About This Product

WSL331 is a work support from the Enerpac WSL series. It has spring advance and lower flange mounting, and locks under hydraulic pressure to support the workpiece during machining. Maximum support force is 33.4 kN (7,500 lbs), stroke is 13.7 mm (0.54 in), maximum operating pressure is 350 bar (5,000 psi) and minimum operating pressure is about 48 bar (700 psi). Oil capacity is 0.24 in³ (about 3.9 cm³), maximum oil flow is 240 in³/min (about 3.9 L/min), and the manifold O-ring is ARP110. It is used in machining fixtures to limit vibration and deflection of thin or flexible workpieces. Support force should be at least 150% of the clamping force.

Features and Benefits

  • Low pressure lock-up allows use with machine tool hydraulic systems
  • High support capacity allows more compact fixture design
  • Corrosion resistant materials, compatible with most coolants and environments
  • Threaded and manifold air vent ports prevent coolant from being drawn into the system
  • Minimized deflection increases machining accuracy
  • Multiple mounting configurations allow design flexibility
