Hollow Plunger Jacks - Double Acting

Ideally suited for pulling and pushing operations in areas such as positioning of cables, ropes and supporting bars, from work for arch supports and handling operation in civil engineering works. These cylinders with suitable attachments can also be sued for extraction and press fitting of bearings, bushes, and shafts.


  • Hollow ram design make these cylinders versatile in pulling operations apart from their usual pushing characteristic. A bar/rope passing through and attached suitably to the ram pushes or pulls the load connected at the other end when the ram moves under pressure.
  • Heat treated alloy steel body.
  • Ram return by oil pressure.
  • Cylinder base provided with fixing holes.
  • Threading on cylinder body, surface treatment on cylinder can be provided on request.
  • Working pressure 700 bar
  • Cylinders tested to ANSI standards.
Higher capacities and strokes are available on request.
Rated capacities and strokes are max. safe limits. As safe practice, use 80% of rated capacity.
