Cast Head Cylinders

Nopak’s cast head cylinders (Class 1 and 2) are designed for rugged industrial and manufacturing environments. Our designs are user-proven, with more than 80 years as the work horse of industry. Class 1 and 2 cylinders use recessed gasketed tube seals and piston to O-ring seals as standard features. Class M cast head mill type cylinders offer all the mounts and features of Class 1 and 2 with an oversize rod and welded flanges. A variety of mounting styles and mounting accessories are available, including parallel base mounting, clevis mounting, right angle flat base mounting, and trunnion mounting. Nopak offers both hydraulic and pneumatic (air) heavy-duty cylinders.

Features:

  • Available for hydraulic and pneumatic (air) power sources.
  • Cylinder Tubes: Hard coated aluminum. Honed and chrome-plated I.D. steel tubing is furnished for 10”-14” diameter cylinders. Class M cylinders have honed steel tubing with welded flanges.
  • Adjustable Cushion: Provides variable cushioning capacity, preventing noisy, damaging metal-to-metal impact of piston against cylinder heads.
  • Leakproof Gasket Seal: Between cylinder wall and head on Class 1 cylinders. Recessed gasket on Class 2 and Class M cylinders.
  • Quick-Opening Ball Check Valve: Assures quick starting under full power. Permits line pressure to act on full piston area instantaneously.
  • Positive Seal V Ring Stack Packing: Three Nylok inserts lock the threaded packing gland in place and maintain proper packing compressions. Larger diameters employ a piston rod bushing packing gland and bolted retainer ring.
