The AirTAC AirTAC SAI200X280-S ISO 15552 Cylinder | 200mm Bore is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø200mm bore and 280mm 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 SAI200X280-S is a robust double-acting ISO 15552 profile cylinder engineered for heavy-duty automation. Delivering a substantial 15708 N push force at 0.5 MPa, this 200 mm bore unit is built to move massive loads reliably. The 280 mm stroke provides ample travel for large-scale material handling. As a genuine AirTAC component, it ensures strict dimensional interchangeability with other ISO 15552 profile cylinders.
This specific configuration features a corrosion-resistant SUS304 stainless steel piston rod (material code B) and PT tapered port threads. The integrated magnet (-S) allows seamless position detection using CMSE or DMSE reed switches, which seat neatly into the dual sensor grooves machined into the extruded aluminum barrel. Adjustable air cushions at both ends absorb kinetic energy, protecting the end caps from impact.

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 high thrust necessary to actuate large stamping dies and heavy-duty forming presses in automotive manufacturing lines.
Drives the opening and closing mechanisms of massive injection molding machinery, handling substantial clamping forces with smooth cushioning.
Powers heavy structural diverters and gates in mining or aggregate conveyors, moving dense bulk materials reliably.
Selecting this 200 mm bore cylinder is ideal when your application requires upward of 15708 N of push force at 0.5 MPa. If your load requirements are slightly lower, stepping down to the 160 mm bore yields 10053 N, which may improve cycle times and reduce air consumption. Because this model features a 280 mm stroke, you must account for potential rod-bearing bending under heavy side loads. Utilizing an external guide rail or a guided cylinder carriage is strongly recommended to prevent premature seal wear.
For drop-in replacements, verify that your existing setup matches the ISO 15552 mounting interface, the G3/4 port size, and the appropriate mounting accessory (such as TC trunnion or FA flange). If the machinery must hold a vertical load securely during an exhaust or pressure loss event, note that the standard adjustable cushion only decelerates the piston and does not function as a brake. In such cases, specify the SAIL variant with an air-released lock or the BSAI bidirectional clamp-lock.
Quick checklist
At an operating pressure of 0.5 MPa, this 200 mm bore cylinder generates 15708 N of push force and 15080 N of pull force. At the maximum theoretical pressure of 1.0 MPa, it can achieve up to 3204 kgf.
Yes, the SAI200X280-S is dimensionally interchangeable per ISO 15552 standards. You can drop it in as a replacement for other ISO 15552 profile cylinders, provided your mounting hardware and G3/4 port connections align.
