About the Airtac SAI200 Standard Cylinder SAI200AX45S
The AirTAC SAI200X45-S is a double-acting ISO 15552 profile cylinder engineered for immense pushing and pulling tasks. Operating at 0.5 MPa, it generates a substantial 15708 N of thrust on the extend stroke and 15080 N on the retract stroke. The short 45 mm stroke is optimal for high-force clamping, pressing, and heavy-duty holding operations where compact actuation is required.
This specific configuration includes a magnet (-S) for direct compatibility with CMSE and DMSE sensor switches, which mount seamlessly into the dual-sided extruded aluminum barrel grooves. Furthermore, this unit is built with an SUS420J2 stainless steel piston rod (material code A) for superior corrosion resistance, and utilizes PT tapered port threads to ensure a robust, leak-free pneumatic connection in demanding industrial environments.

Where the Airtac SAI200 Standard Cylinder SAI200AX45S Is Used
Heavy-Duty Stamping
Provides the intense 15708 N force required to form, stamp, and crimp thick metal components in automated fabrication lines.
Industrial Pressing
Ideal for short-stroke pressing applications where compact movement and massive, stable downward pressure are critical.
Heavy Clamping Systems
Secures large molds or heavy machinery frames during machining operations, utilizing its 15080 N retract force to hold workpieces rigidly.
Is the Airtac SAI200 Standard Cylinder SAI200AX45S the Right Cylinder?
Selecting this 200 mm bore cylinder is appropriate when an application demands extremely high force within a minimal extension distance. If the 15708 N thrust at 0.5 MPa exceeds your requirement, stepping down to the 160 mm bore is advisable, as it provides 10053 N of push force while reducing overall physical footprint and air consumption. Conversely, if your system needs to maintain a load without continuous live air pressure, the standard SAI cylinder will not suffice; the piston will drift upon pressure loss. In such scenarios, the SAIL (air-released lock) or BSAI (bidirectional clamp-lock) variant must be specified.
Because this is a genuine ISO 15552 profile cylinder, it serves as a drop-in replacement for other ISO 15552 cylinders, ensuring strict dimensional interchangeability for mounting interfaces. When integrating this model, match the 200 mm bore, 45 mm stroke, PT G3/4 port, and appropriate mounting accessory (such as a TC trunnion or LB foot). The integrated magnet (-S) allows for precise end-of-stroke position detection.

Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.15 – 1.0 MPa operating pressure.
- check Avoid side load on the piston rod.
- check Adjust end cushion screws for smooth stops.
- check Use correct mounting accessory (FA/FB/CA/CB/LB/TC).
- check Installation by qualified personnel per AirTAC docs.
Airtac SAI200 Standard Cylinder SAI200AX45S FAQ
At a standard operating pressure of 0.5 MPa, this 200 mm bore cylinder delivers a theoretical push force of 15708 N and a pull force of 15080 N. At 0.7 MPa, the push force increases to 21991 N.
Yes. As a true ISO 15552 profile cylinder, it is dimensionally interchangeable with other ISO 15552 cylinders. You can drop it into existing setups utilizing standard mounting accessories, provided you match the G3/4 PT port and 200 mm bore dimensions.
