High Pressure Square-Head Cylinder

Brand: Galland Henning Nopak, Inc

Our Class 3 square head high-pressure hydraulic cylinders are built to NFPA standards and engineered to perform under pressure. These cylinders are constructed from high-strength materials to withstand the most challenging conditions.

Choose from plentiful standard options and custom modifications, including bore sizes up to 50 inches, more than 20 mounting styles, double rod ends, shock-absorbing cushions, and more. The Class 3 model is also available in an oversized mill cylinder, offering the advantages of our field-proven high-pressure cylinder design integrity in a non-tie-rod unit. Our team can even engineer these cylinders for water service.
Features
  • Available for hydraulic and pneumatic (air) power sources
  • Cushion Adjustment Needle: Needle valves and ball check drilling and machining are identical, making location of these functions interchangeable
  • Piston: High strength, fine grain cast iron piston fitted with split “Tongue-seal” cast iron piston rings on either side of a homogenous “T” ring supplied with back-up rings. “T” ring furnished on all models; oversized are fitted with piston rings The outboard piston rings effectively seal off initial shock loads and allow the “T” ring to provide a leak-proof piston seal with maximum life
  • Heavy Wall: Steel tubing, precision honed with extra-long stones to provide overlap and eliminate a spiral condition detrimental to long stroke cylinders. The resulting ultra-smooth finish provides maximum seal life
  • Cushion Sleeves: Precision fitted with predetermined taper to provide a gradual deceleration and reduce shock
  • Tie Rod: Material stress-proof steel for maximum strength. Multiple tie-rods in each corner are furnished on all models, 10”-20” diameter bores
  • Piston Rod: High tensile 100,000 PSI minimum yield stress-proof steel, ground, polished, and flash chrome plated .0003/.0005 to provide a hard, long-wearing surface with low friction, but not corrosion resistant
