The AirTAC AirTAC SAI200X260-S ISO 15552 Cylinder | 200mm Bore is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø200mm bore and 260mm 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 SAI200X260-S is a double-acting ISO 15552 profile cylinder engineered for heavy-duty operations, delivering a substantial push force of 15708 N at 0.5 MPa and 21991 N at 0.7 MPa. With a 200 mm bore and 260 mm stroke, this extruded aluminum barrel unit operates at speeds of 30-500 mm/s and features adjustable air cushions at both ends to absorb high impact energies.
Equipped with a -S magnet, this model directly supports CMSE and DMSE sensor switches via integrated dual-side grooves. It utilizes a standard carbon steel piston rod and PT tapered port threads, ensuring robust performance and secure pneumatic connections for massive actuation tasks.

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 to form and stamp thick-gauge sheet metal components in automated fabrication lines.
Utilizes the integrated -S magnet and CMSE sensors to precisely confirm ejection strokes for oversized plastic automotive interior molds.
Drives heavy-duty lifting arms in end-of-line palletizing robotic cells, moving substantial product loads with reliable 0.15-1.0 MPa pressure control.
Selecting this 200 mm bore is ideal when the 160 mm variant (providing 10053 N push at 0.5 MPa) lacks the necessary thrust for heavy lifting. At a 260 mm stroke, the unsupported rod length is moderate, but side loads can still accelerate rod-bearing wear; utilizing an external guide rail prevents bending and extends seal life. For applications needing absolute position retention during a complete air loss event, note that the standard adjustable cushion only decelerates the piston at stroke end and does not function as a lock—integrate the SAIL (air-released lock) or BSAI (bidirectional clamp-lock) variant for fail-safe load holding.
As a true ISO 15552 profile cylinder, it offers a dimensionally interchangeable mounting interface, serving as a drop-in replacement for other ISO 15552 cylinders. Replacement and mounting configurations should match the 200 mm bore, 260 mm stroke, G3/4 PT port, and compatible FA/FB flange or TC trunnion accessories.
Quick checklist
This 200 mm bore cylinder generates a push force of 15708 N and a pull force of 15080 N at 0.5 MPa. At 0.7 MPa, the push force increases to 21991 N.
No, the standard SAI cylinder does not hold its load without live pressure. The adjustable air cushion only decelerates the piston near the stroke end. For secure position holding during pressure loss, you must use the SAIL lock or BSAI clamp-lock variant.
