The AirTAC AirTAC SAI200X40-S ISO 15552 Cylinder | 200mm Bore is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø200mm bore and 40mm 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 SAI200X40-S is a double-acting ISO 15552 profile cylinder engineered for immense pushing and pulling power. It generates 15708 N of thrust at just 0.5 MPa, scaling up to a theoretical maximum of 3204 kgf at 1.0 MPa. The short 40 mm stroke is purpose-built for high-force clamping, pressing, and heavy-duty holding tasks where space is restricted.
This variant features a SUS304 stainless steel rod for superior corrosion resistance and includes a built-in magnet for direct compatibility with CMSE and DMSE sensor switches. The extruded aluminum barrel incorporates sensor grooves on both sides, and fluid connections use PT tapered threads sized at G3/4.

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.
Executes short-travel, high-force pressing operations in metal forming lines, utilizing 21991 N of thrust at 0.7 MPa to seat components firmly.
Secures massive workpieces during machining or welding, using the robust SUS304 rod to withstand harsh, debris-rich environments.
Provides the intense burst of force required to eject dense molded parts from tooling cavities within a compact 40 mm stroke.
Select this 200 mm bore actuator when a 160 mm cylinder (providing 10053 N at 0.5 MPa) cannot meet your force requirements. Because the stroke is only 40 mm, rod-bearing bending is negligible, eliminating the need for external guides. For operations requiring the load to remain fixed during a complete loss of air pressure, integrate an external pilot-operated check valve or specify the BSAI clamp-lock variant, as standard air cushions only decelerate the piston at end-of-stroke.
This model provides a true ISO 15552 mounting interface, ensuring drop-in compatibility with existing standard foot, flange, and trunnion hardware. The -S suffix confirms the magnetic piston is installed for position sensing.
Quick checklist
At an operating pressure of 0.5 MPa, this 200 mm bore cylinder provides 15708 N of push force and 15080 N of pull force. At 0.7 MPa, the push force increases to 21991 N.
Yes. The SAI200X40-S is built to the ISO 15552 standard, meaning its mounting dimensions are fully interchangeable with equivalent ISO 15552 profile cylinders from other manufacturers.
