About the Airtac SAI200 Standard Cylinder SAI200AX475S
The AirTAC SAI200X475-S is a double-acting ISO 15552 profile cylinder engineered for heavy-duty automation. With a 200mm bore and a 475mm stroke, it generates a robust push force of 15708 N at 0.5 MPa and reaches a maximum of 21991 N at 0.7 MPa. This specific configuration includes a SUS420J2 stainless steel piston rod (option A) for superior corrosion resistance in harsh environments.
Equipped with a built-in magnet (-S), the barrel features sensor grooves on both sides for seamless integration with CMSE or DMSE reed switches. The pneumatic ports utilize PT tapered threads, and adjustable air cushions at both ends effectively decelerate the massive 200mm piston. This model is a genuine AirTAC component, ensuring reliable, high-force linear motion.

Where the Airtac SAI200 Standard Cylinder SAI200AX475S Is Used
Heavy Metal Stamping
Provides the immense 21991 N output force at 0.7 MPa required to operate large-scale mechanical presses and form thick metal sheets.
Plastic Injection Unloading
Ejects heavy molded automotive parts from large injection molding machines, utilizing the 475mm stroke to clear the mold area completely.
Large Clamp Actuation
Drives massive clamping fixtures in structural steel fabrication, relying on the SUS420J2 rod to withstand industrial moisture and stress.
Is the Airtac SAI200 Standard Cylinder SAI200AX475S the Right Cylinder?
Selecting this 200mm bore cylinder is ideal when applications require extreme thrust that smaller bores cannot provide, such as heavy stamping or large mold handling. If 15708 N at 0.5 MPa is excessive, dropping to a 160mm bore yields 10053 N, offering a lighter footprint and faster cycle times. Conversely, if your system needs to safely hold a load during a pressure loss, this standard cylinder will drift; you must specify an SAIL (pneumatic lock) or BSAI (clamp-lock) variant instead.
At a 475mm stroke, the extended rod is highly susceptible to bending under side loads. To prevent premature rod-bearing wear and piston scoring, mount external guide rails or employ a fully guided cylinder mechanism to absorb lateral forces. Ensure your ISO 15552 mounting interface uses heavy-duty trunnion (TC) or clevis (CA) accessories to handle the substantial weight and inertia of this bore size.
Quick checklist
- ✓ Required force at your working pressure
- ✓ Stroke and mounting space
- ✓ Port/thread type (PT/NPT/G)
- ✓ Magnet (-S) for sensors?
- ✓ Side load — consider a guided cylinder
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 SAI200AX475S FAQ
At 0.5 MPa, this 200mm bore cylinder provides a push force of 15708 N. If you operate at 0.7 MPa, the push force increases to 21991 N.
Yes, the SAI200X475-S is dimensionally interchangeable per ISO 15552. You can drop it in to replace other ISO 15552 profile cylinders, matching the bore, stroke, and PT port connections.
