About the Airtac SAI200 Standard Cylinder SAI200AX260S
The AirTAC SAI200X260-S is a double-acting ISO 15552 profile cylinder engineered for heavy-duty automation. It provides a substantial push force of 15708 N and a pull force of 15080 N at 0.5 MPa, making it well-suited for moving massive loads over a 260 mm stroke. The extruded aluminum barrel design omits tie rods for a clean exterior.
This specific configuration includes a SUS420J2 stainless steel piston rod (material code A) for enhanced corrosion resistance. The -S suffix indicates a built-in magnet for position sensing, allowing seamless integration with CMSE or DMSE switches mounted directly into the dual sensor grooves. Fluid ports feature PT tapered threading, and the cylinder incorporates adjustable air cushions at both ends to absorb kinetic energy.

Where the Airtac SAI200 Standard Cylinder SAI200AX260S Is Used
Heavy Metal Forming
Provides the 15708 N push force required to actuate large stamping presses and heavy-gauge metal bending fixtures at 0.5 MPa.
Injection Mold Handling
Shifts substantial injection molding tooling safely, utilizing the SUS420J2 rod to resist moisture in humid factory environments.
Pallet Positioning
Indexes loaded pallets on high-capacity conveyor lines, relying on adjustable air cushions to stop the 200 mm bore smoothly.
Is the Airtac SAI200 Standard Cylinder SAI200AX260S the Right Cylinder?
Selecting this 200 mm bore unit is appropriate when application thrust requirements exceed the 10053 N push force of the 160 mm bore variant. Operating speed ranges from 30-500 mm/s. For this 260 mm stroke, the unsupported rod length is moderate, but mounting alignment remains critical to prevent premature rod seal wear. Utilize FA or FB flange accessories to maintain strict perpendicularity.
Because this is a standard double-acting cylinder, it will not maintain its position if air pressure drops. The adjustable end cushions decelerate the piston but do not act as a mechanical brake. If the machinery requires fail-safe load holding, consider the BSAI bidirectional clamp-lock variant or install an external pilot-operated check valve. This model serves as a direct dimensional drop-in for any ISO 15552 profile cylinder footprint.
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 SAI200AX260S FAQ
At an operating pressure of 0.5 MPa, this 200 mm bore cylinder 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 SAI200X260-S is dimensionally interchangeable per ISO 15552. You can drop it into existing mountings matching the standard 200 mm bore profile footprint without modifying the machine frame.
