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 double-acting ISO 15552 profile cylinder engineered for extreme thrust requirements, delivering 15708 N push force at 0.5 MPa and 21991 N at 0.7 MPa. With a 70 mm stroke, this unit is tailored for short, high-impact pressing operations. The extruded aluminum barrel omits tie rods, ensuring a clean exterior that matches standardized ISO 15552 mounting dimensions for seamless interchangeability.
This specific configuration includes a SUS304 stainless steel rod (option B) for superior corrosion resistance in humid or washdown environments. It features PT tapered ports and an integrated magnet (-S) that interfaces directly with CMSE and DMSE sensor switches housed in the dual side grooves. For applications needing position holding without air pressure, consider the SAIL or BSAI clamp-lock variants.

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 21991 N push force at 0.7 MPa required for short-stroke stamping, bending, and forming thick metal plates.
Acts as a pneumatic alternative for high-force pressing tasks where hydraulic systems are too slow or messy for the workflow.
Secures massive workpieces or structural components during heavy machining operations using its robust 200 mm profile barrel.
Selecting this 200 mm bore cylinder is appropriate when the 160 mm bore (10053 N push at 0.5 MPa) lacks sufficient power for heavy lifting or pressing. The 70 mm stroke keeps the retracted length manageable while providing targeted high-force movement. Operating speed ranges from 30-500 mm/s, driven by G3/4 PT ports.
Because the standard SAI is double-acting, air pressure is required on both sides of the piston to extend and retract the rod; it will not hold a load if pressure is exhausted. The adjustable air cushions at both ends decelerate the piston to prevent end-cap impact, but they do not function as a mechanical brake. Mounting accessories include FA/FB flanges and CA/CB clevises to match your ISO 15552 footprint.
Quick checklist
At 0.5 MPa operating pressure, the SAI200X70-S generates 15708 N of push force and 15080 N of pull force. At 0.7 MPa, the push force increases to 21991 N.
Yes, the SAI200X70-S is a genuine profile cylinder built to ISO 15552 dimensional standards, making it a drop-in replacement for other ISO 15552 cylinders with matching 200 mm bores.
