SU-Series, Upper Flange Model Swing Cylinders

  • Enerpac upper flange model swing cylinders require minimal mounting height for when space is at a premium
  • Flexible design allows for manifold or threaded port connection
  • Low profile mounting style allows body to be below mounting surface
  • Simple mounting preparation and easy installation – 3 or 4 mounting bolts
  • Double oil connection – threaded port or manifold mount
  • Symmetrical rectangular flange design enables clamping at three sides of the cylinder
  • 30, 45, and 60 degree swing angles available on request

1) With standard clamp arm. Clamp arms are sold separately. Clamping forces for single-acting models are reduced in order to overcome return spring force.
2) For models with straight plunger movement, replace L or R with S.
