The AirTAC AirTAC SAI200X75-S ISO 15552 Cylinder | 200mm Bore is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø200mm bore and 75mm 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 SAI200X75-S is a double-acting ISO 15552 profile cylinder engineered for extreme force tasks, delivering a formidable 15708 N push force at just 0.5 MPa. Its 75 mm stroke provides rapid, high-impact linear motion within compact machinery envelopes. The extruded aluminum barrel design omits traditional tie-rods, offering a clean exterior that integrates seamlessly into heavy-duty assemblies.
This specific configuration features a SUS420J2 stainless steel piston rod (material code A) for superior corrosion resistance in humid or chemically active settings. Equipped with a magnetic piston (-S), it directly supports CMSE and DMSE reed switches via dual sensor grooves machined into both sides of the barrel. Fluid porting utilizes PT tapered threads, ensuring robust, leak-free pneumatic connections under high flow demands.

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 form, punch, and stamp thick metal sheets in automated fabrication lines.
Drives short-stroke hydraulic and pneumatic presses where high impact energy must be delivered over a compact 75 mm travel distance.
Exerts relentless holding power to secure oversized workpieces during heavy machining, welding, and structural assembly processes.
Selecting this 200 mm bore is appropriate when operations require massive thrust that smaller bores cannot achieve, such as heavily displacing the 160 mm option which yields 10053 N at 0.5 MPa. Because the stroke is relatively short at 75 mm, rod-bearing bending stress is minimal, but always verify that external loads are guided to prevent side-load damage to the piston rod. As a true ISO 15552 standardized unit, this cylinder serves as a drop-in replacement for any equivalent profile cylinder matching the 200 mm bore, 75 mm stroke, PT G3/4 ports, and standard mounting accessory dimensions.
If your machinery loses air pressure, this standard SAI cylinder cannot hold a suspended load and will drift downward. For fail-safe position holding, consider the SAIL variant with an air-released lock, or the BSAI bidirectional clamp-lock cylinder.
Quick checklist
At a 0.5 MPa operating pressure, this 200 mm bore cylinder generates 15708 N of push force and 15080 N of pull force. It can reach up to 21991 N push at 0.7 MPa.
Yes, the SAI200X75-S is a genuine ISO 15552 profile cylinder. It is dimensionally interchangeable with other ISO 15552 cylinders of the same bore and stroke, utilizing standard G3/4 PT ports and standard mounting interfaces.
