About This Product

WFL331 is a lower flange, hydraulic advance work support from the Enerpac WFL series. Maximum support force is 33.4 kN (7,500 lbs), stroke is 13.5 mm (0.53 in), maximum operating pressure is 345 bar (5,000 psi) and minimum operating pressure is about 48 bar (700 psi). Oil capacity is 0.24 in³ and maximum oil flow is 240 in³/min. Mounting diameter is 2.88 in, contact bolt thread is M20 x 2.5 and the manifold O-ring is ARP110. Plunger retract spring force is 17.5 lbs. It is used in fixtures to support the workpiece during machining. Support force must be matched to clamping force; support force should be at least 150% of clamping force.

Features and Benefits

  • Plunger stays retracted until pressure is applied, allowing unobstructed loading
  • Low pressure lock-up enables 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 help keep coolant and debris out of the mechanism
  • Contact bolt included; minimized deflection improves machining accuracy
