The AirTAC AirTAC SAI200X70-S ISO 15552 Cylinder | 200mm Bore is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø200mm bore and 70mm 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 SAI200X70-S is a genuine double-acting ISO 15552 profile cylinder engineered for immense pushing power, delivering 15708 N of thrust at just 0.5 MPa. With a 200mm bore and a 70mm stroke, this tie-rod-less actuator is purpose-built for heavy-duty press and lift cycles requiring immediate, high-impact force over a short distance.
Configured with a standard carbon steel piston rod and a built-in magnet (-S), the extruded aluminum barrel features dual sensor grooves for direct mounting of CMSE or DMSE reed switches. The standard TPU seals handle ambient temperatures up to 70 C, while a Viton (H) seal alternative is available for hotter environments.

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 massive 15708 N push force required to drive short-stroke stamping and forming dies at the bottom of heavy press lines.
Delivers consistent 15080 N pull force to seat large bearings or bushings into heavy machinery housings during automated assembly.
Generates enough raw lifting thrust to elevate loaded heavy-duty pallets or industrial molds over a compact 70mm vertical clearance.
Selecting this 200mm bore actuator is ideal when 160mm bore cylinders (providing 10053 N at 0.5 MPa) lack the necessary push force for extreme loads. Although the 70mm stroke is short and highly resistant to rod-bearing bending, any application involving offset loads should still utilize an external guide rail to prevent premature wear. Because this is a standard double-acting cylinder, it cannot hold a load if air pressure drops; for fail-safe positioning, integrate the SAIL variant with an air-released lock or an external pilot-operated check valve. As a true ISO 15552 profile cylinder, it serves as a dimensionally interchangeable drop-in replacement for other ISO 15552 cylinders, utilizing a G3/4 PT port and compatible FA/FB flange or TC trunnion mounting accessories.
Quick checklist
At 0.5 MPa operating pressure, this 200mm 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 SAI200X70-S relies on live air pressure and cannot hold a load if pressure is lost. For suspended load safety, use the SAIL variant with an air-released lock or an external rod lock.
