The AirTAC AirTAC SAI200X400-S ISO 15552 Cylinder | 200mm Bore is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø200mm bore and 400mm 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 SAI200X400-S is a double-acting ISO 15552 profile cylinder engineered for heavy-duty automation. Delivering a robust 15708 N push force at 0.5 MPa, this 200 mm bore unit handles massive loads across its 400 mm stroke. The extruded aluminum barrel design omits tie-rods, providing a clean exterior that drops directly into existing ISO 15552 mounting footprints.
This specific configuration includes a -S magnet for direct mounting of CMSE or DMSE reed switches along the dual sensor grooves. It is built with a SUS304 stainless steel rod for superior corrosion resistance and utilizes PT tapered port threads. For environments requiring elevated temperatures, the standard TPU seals can be swapped for Viton (H) options.

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 required to actuate large mechanical stamping presses and heavy gauge metal forming dies.
Drives massive industrial assembly presses, securely seating large automotive or structural components with precise 400 mm travel.
Shifts and positions fully loaded heavy-duty pallets or industrial molds, utilizing the integrated magnet for stroke position verification.
Select this 200 mm bore model when 160 mm (9425 N pull at 0.5 MPa) lacks the necessary thrust for your heaviest payloads. Because this cylinder features a 400 mm stroke, the extended rod is highly susceptible to bending under side loads. Utilize external guide rails or a dedicated guided cylinder to prevent premature rod-bearing wear.
As a true ISO 15552 profile cylinder, it is dimensionally interchangeable with other ISO 15552 cylinders, matching the 200 mm bore, 400 mm stroke, G3/4 port, and standard mounting accessories like TC trunnions or FA flanges. Note that standard air cushions only decelerate the piston at stroke ends; if the application must hold a load safely without live air pressure, specify the BSAI clamp-lock variant or use an external rod lock.
Quick checklist
At 0.5 MPa operating pressure, 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.
No, the standard SAI cylinder will drift or drop if air pressure is lost. The adjustable air cushions only decelerate the piston at the end of the stroke. For fail-safe load holding, use the BSAI clamp-lock variant or an external rod lock.
