About the Airtac SAI200 Standard Cylinder SAI200AX40
The AirTAC SAI200X40 is a double-acting ISO 15552 profile cylinder engineered for extreme thrust in compact movement ranges. Delivering a theoretical push force of 15708 N at 0.5 MPa, this 200mm bore unit utilizes a short 40mm stroke to execute high-impact clamping or pressing operations. The extruded aluminum barrel design omits tie-rods, providing a clean exterior that drops directly into standardized ISO 15552 mounting footprints.
This specific configuration features a SUS420J2 stainless steel piston rod (material code A) for enhanced corrosion resistance in humid or mildly chemically washed environments. Fluid supply connects via PT tapered ports, and because no magnet is specified, it operates without internal sensor tracks. For applications requiring position holding without constant air pressure, the SAIL variant offers an integrated air-released lock mechanism.

Where the Airtac SAI200 Standard Cylinder SAI200AX40 Is Used
Heavy-Duty Stamping
Provides the intense 15708 N push force required to form, stamp, or pierce thick metal plates within a tight 40mm working distance.
Industrial Clamping
Secures massive workpieces or structural weldments in place during heavy machining operations using robust PT port connections and a rigid 200mm bore.
High-Force Ejection
Ejects dense finished parts or heavy scrap from press beds rapidly, utilizing the SUS420J2 stainless steel rod to withstand abrasive industrial environments.
Is the Airtac SAI200 Standard Cylinder SAI200AX40 the Right Cylinder?
Selecting the SAI200X40 is optimal when a process demands immense power over a very short distance. If a slightly lower footprint is acceptable, stepping down to a 160mm bore reduces the 0.5 MPa push force to 10053 N while saving significant physical space. Conversely, if the 40mm stroke is insufficient but the 200mm bore class is required, longer standard strokes up to 1500mm are available. Because this cylinder generates 15708 N of force, ensure your mounting structure and rod end connections are rated for heavy shock loads.
As a standard double-acting actuator, this model relies entirely on continuous air pressure to maintain its rod position; it will drift if supply is exhausted or a valve is centered. The integrated adjustable air cushions at both ends decelerate the piston near stroke ends to prevent impact damage, but they do not function as a braking or locking mechanism. Replacement planning should match the exact 200mm bore, 40mm stroke, PT port thread, and desired mounting accessory type (such as FA flange or TC trunnion).
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 SAI200AX40 FAQ
At a standard operating pressure of 0.5 MPa, the SAI200X40 generates a push force of 15708 N and a pull force of 15080 N. At 0.7 MPa, the push force increases to 21991 N.
Yes, the SAI200X40 is dimensionally interchangeable per ISO 15552 standards. You can drop it into existing ISO 15552 mounting hardware, provided you match the 200mm bore, 40mm stroke, and PT port configuration.
