About the Airtac SAI200 Standard Cylinder SAI200AX290
The AirTAC SAI200X290 is a double-acting ISO 15552 profile cylinder engineered for heavy-duty automation. Delivering a substantial 15708 N push force at 0.5 MPa, this 200mm bore unit handles massive payloads across its 290mm stroke. The extruded aluminum barrel design omits tie rods, presenting a clean exterior that is dimensionally interchangeable with other ISO 15552 cylinders.
Configured here with a SUS420J2 stainless steel rod (material code A) for superior corrosion resistance, this model features PT tapered port threads. Because no magnet (-S) is specified, it operates without electronic position sensing, relying instead on its adjustable air cushions at both ends to decelerate the heavy piston smoothly.

Where the Airtac SAI200 Standard Cylinder SAI200AX290 Is Used
Heavy Stamping Presses
Generates the 15708 N of thrust at 0.5 MPa required to actuate large metal forming and stamping presses.
Large Injection Molding
Provides the robust extraction force needed to pull heavy molded plastic automotive parts from large injection molds.
Industrial Machinery Dampening
Uses its adjustable end-of-stroke air cushions to safely decelerate massive moving components in heavy industrial machinery.
Is the Airtac SAI200 Standard Cylinder SAI200AX290 the Right Cylinder?
Selecting this 200mm bore is appropriate when 160mm (9425 N pull at 0.5 MPa) lacks the necessary thrust for your heaviest lifting tasks. At a 290mm stroke, the unsupported rod length is significant; side loads can bend the rod bearing and cause premature seal failure. To manage this, mount external guide rails or utilize a fully guided cylinder to absorb lateral forces.
As a true ISO 15552 cylinder, it serves as a direct dimensional drop-in replacement for other 200mm profile cylinders sharing the same mounting interface, 290mm stroke, and G3/4 port size. Note that if your machinery requires the load to be physically held in place during a complete air pressure loss, the standard SAI will drift; you should specify the SAIL (air-released lock) or BSAI (bidirectional clamp-lock) variant instead of relying on the cushion.
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 SAI200AX290 FAQ
At 0.5 MPa, the push force is 15708 N and the pull force is 15080 N. If operating at 0.7 MPa, the push force increases to 21991 N.
No, the standard SAI cylinder does not hold position without live air pressure and will drift downwards. For secure load holding, use the SAIL variant with an air-released lock or the BSAI bidirectional clamp-lock.
