The AirTAC AirTAC SAI200X280 ISO 15552 Cylinder | 200mm Bore is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø200mm bore and 280mm stroke, G3/4 air ports and adjustable end cushioning. Its standardized mounting interface makes it a drop-in replacement for other ISO 15552 cylinders in automation lines.
The AirTAC SAI200X280 is a double-acting ISO 15552 profile cylinder built for heavy-duty automation. It provides a robust push force of 15708 N at 0.5 MPa, making it ideal for high-mass pressing and lifting. The 280 mm stroke handles substantial linear travel without exceeding the 1500 mm standard limit. Its extruded aluminum barrel design omits tie rods for a cleaner exterior. This configuration uses a standard carbon steel piston rod and PT tapered port threads. Because it lacks a magnet, external reed or solid-state sensors cannot be mounted directly. For operations requiring end-of-stroke confirmation, specify the -S variant for dual-side sensor grooves compatible with CMSE and DMSE switches.

Related SAI-family variants: SAID (double rod), SAIJ (adjustable stroke), SAIL (with lock), SAIF (with valve), BSAI (enclasp / clamp-lock), and SAI-S with built-in magnet. Rod material: carbon steel (blank) / SUS420J2 (A) / SUS304 (B); seals: TPU (blank) / Viton H / NBR N.
Provides the immense 15708 N push force at 0.5 MPa required to form and stamp thick metal components in automated fabrication lines.
Handles large-tonnage clamping and forming tasks where stable, high-force linear actuation is critical over a 280 mm travel distance.
Actuates heavy-duty diverter gates and large structural loads on bulk material conveyors where lower bore cylinders lack the necessary thrust.
Select this 200 mm bore when 160 mm (yielding 10053 N at 0.5 MPa) cannot generate enough thrust to move your load. For applications needing absolute position holding during a pressure loss or valve centering, note that the standard adjustable air cushions only decelerate the piston and do not function as a brake. You must integrate an external pilot-operated check valve or select the SAIL (air-released lock) or BSAI (bidirectional clamp-lock) variant. Since the stroke is 280 mm, side loads can cause rod-bearing bending and premature wear; guide heavy loads externally or use a guided cylinder to prevent rod deflection. As a true ISO 15552 profile cylinder, it serves as a drop-in replacement matching the 200 mm bore, 280 mm stroke, G3/8 port, and standard mounting accessory dimensions.
Quick checklist
The SAI200X280 generates a push force of 15708 N and a pull force of 15080 N at 0.5 MPa. At 0.7 MPa, the push force increases to 21991 N.
No, the standard SAI200X280 cannot hold a load without live pressure; the adjustable air cushions only decelerate the piston near stroke ends. For secure position holding, use the SAIL or BSAI lock variant, or add an external rod lock.
