The AirTAC AirTAC SAI200X65-S ISO 15552 Cylinder | 200mm Bore is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø200mm bore and 65mm 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 SAI200X65-S is a double-acting ISO 15552 profile cylinder engineered for heavy-duty linear motion. Operating at 0.5 MPa, it generates a substantial push force of 15708 N and a pull force of 15080 N. The 65 mm stroke provides a compact extension length for high-thrust pressing, clamping, and holding tasks.
This configuration includes a SUS420J2 stainless steel piston rod (material code A) for enhanced corrosion resistance compared to standard carbon steel. The barrel features sensor grooves on both sides, and the integrated magnet (-S) allows direct mounting of CMSE or DMSE reed switches for precise end-of-stroke detection. Fluid ports feature PT tapered threads.

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 15708 N push force at 0.5 MPa required for forming, stamping, and pressing rigid materials in automated fabrication lines.
Secures large molds or heavy workpieces during machining, utilizing the 15080 N pull force and short 65 mm stroke for rigid, zero-play holding.
Delivers high-impact ejection force to release large finished parts from molds, with CMSE sensors verifying the ejector position.
Select this 200 mm bore actuator when an application requires extreme thrust that smaller bores cannot provide, such as stepping up from a 160 mm bore that yields 10053 N at 0.5 MPa. The short 65 mm stroke is optimal for minimizing rod-bearing bending stress during high-force operations. Because the stroke is under 300 mm, side-load risks are naturally lower than on longer units, though external guides are still recommended for offset loads.
As a true ISO 15552 profile cylinder, it offers a dimensionally interchangeable mounting interface for seamless drop-in replacement of other ISO 15552 cylinders. To match this specific unit, specify the 200 mm bore, 65 mm stroke, PT G3/4 ports, and the -S magnet option. Note that standard air cushions only decelerate the piston at end-of-stroke; they do not hold a load. If pressure drops, the rod will drift. For position holding without live air pressure, use an external pilot-operated check valve or the BSAI clamp-lock variant.
Quick checklist
At 0.5 MPa, this double-acting cylinder provides a push force of 15708 N and a pull force of 15080 N. At 0.7 MPa, the push force increases to 21991 N.
Yes, the SAI200X65-S is a genuine ISO 15552 profile cylinder. Its standardized mounting dimensions make it a drop-in replacement for other ISO 15552 cylinders, provided you match the 200 mm bore, 65 mm stroke, and G3/4 port size.
