HHA Range

The HHA range of single acting hollow piston aluminum cylinders are specifically designed for applications where weight and ease of positioning are of prime importance. Similar in design to the HHS range, the HHA cylinder models have a hollow piston to enable a rod or cable to be passed through the entire cylinder length making it suitable for applications where a pulling force is required. All models are supplied with a hard anodised, wear resistant, piston rod and cylinder body and a steel cylinder base protection plate.

  • Capacities from 18 to 52 tonnes
  • Stroke lengths from 51 to 105 mm
  • Working pressure 700 bar
  • Spring assisted return
  • Hard anodised piston rod and cylinder
  • Steel base plate to protect cylinder body
  • Low friction bearing surfaces
  • Optional piston rod saddles
