About the Airtac SAI200 Standard Cylinder SAI200AX290S
The AirTAC SAI200X290-S is a double-acting ISO 15552 profile cylinder engineered for heavy-duty automation. Delivering a substantial 15708 N of push force at just 0.5 MPa, it tackles high-mass displacement tasks with ease. This 200 mm bore unit features a 290 mm stroke and includes a piston magnet for seamless integration with CMSE and DMSE reed switches.
Built to handle demanding environments, this specific configuration utilizes a SUS420J2 stainless steel rod for superior corrosion resistance. The extruded aluminum barrel design omits tie-rods, providing a clean profile that is dimensionally interchangeable with other ISO 15552 actuators. Fluid ports feature PT tapered threading, ensuring robust, leak-free pneumatic connections.

Where the Airtac SAI200 Standard Cylinder SAI200AX290S Is Used
Heavy Metal Stamping
Provides the high clamping force needed to secure large metal sheets during heavy-duty stamping and punching operations.
Automotive Assembly Jigs
Actuates massive structural fixtures and positioning jigs on automotive assembly lines where high mass must be moved reliably.
Pallet Load Diversion
Drives heavy-duty diverter arms to redirect fully loaded pallets along high-throughput material handling conveyors.
Is the Airtac SAI200 Standard Cylinder SAI200AX290S the Right Cylinder?
Selecting this 200 mm bore over the 160 mm variant steps the output up from 10053 N to 15708 N at 0.5 MPa, which is critical when moving exceptionally heavy payloads. Because the 290 mm stroke generates significant extension length, long unsupported rods are susceptible to bending under side loads. For applications involving heavy offset loads, implement an external guide rail or select a guided cylinder to prevent premature rod-bearing wear.
Remember that the standard double-acting SAI relies on air pressure for movement and will not hold a load if pressure drops. The adjustable air cushions only decelerate the piston near the stroke ends. If your application requires true position holding without live pressure, consider the SAIL locking variant or an external pilot-operated check valve.
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.
