About the Airtac SAI50 Standard Cylinder SAI50AX225S
The AirTAC SAI50X225-S is a double-acting ISO 15552 profile cylinder featuring a 50mm bore and a 225mm stroke. Because this stroke falls outside the standard increments, it is supplied as a made-to-order variant, ensuring you get the exact travel distance required for your machine layout. It delivers a robust push force of 982 N at 0.5 MPa, making it well-suited for moderate-load handling and positioning tasks.
This specific configuration includes a SUS420J2 stainless steel rod (material code A) for enhanced corrosion resistance in humid or mildly wash-down environments. The -S suffix indicates an integrated magnet for use with CMSE and DMSE series reed switches, which mount directly into the extruded aluminum barrel's dual sensor grooves. Fluid ports are PT (tapered) thread type.

Where the Airtac SAI50 Standard Cylinder SAI50AX225S Is Used
Automated Assembly
Provides reliable clamping and actuation for component insertion stations requiring precise 225mm travel.
Material Handling
Ideal for pushing or diverting packages on processing lines where the 982 N force easily moves moderate loads.
Packaging Machinery
Used in case erecting and palletizing cells, where the SUS420J2 rod withstands varied operational environments.
Is the Airtac SAI50 Standard Cylinder SAI50AX225S the Right Cylinder?
When selecting this actuator, compare its 982 N output at 0.5 MPa against the neighboring 40mm bore, which yields 628 N. If your application requires lifting heavier payloads, stepping up to the 63mm bore provides 1559 N of thrust. Because the 225mm stroke is a non-standard dimension, verify your overall length envelopes before finalizing the design.
For a stroke of this length, side loads can cause rod-bearing bending and premature wear; utilizing an external guide rail or a guided cylinder is strongly recommended to prevent rod deflection. This standard double-acting cylinder relies on air pressure to hold its position—if your application must hold a load safely when air pressure is exhausted or the valve is centered, consider the SAIL (air-released lock) variant or an external pilot-operated check valve. As a true ISO 15552 profile barrel, it serves as a dimensionally interchangeable direct replacement for other ISO 15552 cylinders, matching the 50mm bore, 225mm stroke, PT port, and standard mounting accessories like FA flanges or LB foot brackets.
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 SAI50 Standard Cylinder SAI50AX225S FAQ
At 0.5 MPa operating pressure, this 50mm bore cylinder generates a push force of 982 N. If operated at 0.7 MPa, the push force increases to 1374 N.
Yes, the SAI50X225-S is a genuine ISO 15552 profile cylinder, meaning its mounting dimensions are fully interchangeable with other standard ISO 15552 cylinders of the same bore and stroke.
