Overall dimensions and technical information are provided solely for informative purposes and may be modified without notice Cylinders according to standard ISO 15552 Series Steel line - AISI 316 3 Pneumatic actuation 3 | 77 Series Steel line - AISI 316 The 1393-1394 stainless steel ISO 15552 cylinders series are designed for corrosion resistance application such as marine, pharmaceutical and food ambiences. The pre lubrication grease used is NSF H1 certified for food application. Specific care has been taken during the design stages and the result is a clean profile cylinder easy to clean and free from possible residue build-up areas. All parts in contact with the external environment are in Stainless steel 316L and the seals are available in two different compounds for different temperature applications: PUR -30°C ... +80°C FPM -5°C ... +150°C. The range starts from 32 bore up to 100 bore , round barrel and tie rods design. Double acting version standard or with through rod, magnetic or not magnetic piston available. The piston is aluminium and the sensor bracket, when required is in stainless steel 316. The cylinder can be fixed via the threaded holes in the tie rod nuts or with the wide range of stainless steel accessories.

Please note: air must be dried for applications with lower temperature. Standard strokes (for all diameters) from 0 to 150, every 25 mm from 150 to 500, every 50 mm from 500 to 1000, every 100 mm On request are available strokes up to: 2800 mm Stroke tolerance (ISO 15552) Bore Stroke Tolerance 32-40-50 up to 500 mm +2 0 over 500 up to 1000 +3,2 0 63-80-100 up to 500 mm +2,5 0 over 500 up to 1000 +4 0
