About the Airtac SAI50 Standard Cylinder SAI50AX100
The AirTAC SAI50X100 is a double-acting ISO 15552 profile cylinder engineered to deliver 982 N of push force at 0.5 MPa. Its 100 mm stroke provides a compact yet powerful linear motion solution for medium-duty machinery.
This specific configuration utilizes a SUS420J2 stainless steel piston rod for enhanced corrosion resistance compared to standard carbon steel. It features PT tapered port threads and lacks a standard magnet, meaning it is optimized purely for mechanical actuation rather than electronic position sensing.

Where the Airtac SAI50 Standard Cylinder SAI50AX100 Is Used
Clamping Fixtures
Provides reliable 982 N clamping force at 0.5 MPa for securing medium-sized metal or composite workpieces during secondary machining operations.
Package Diverters
Actuates routing gates and pusher arms on packaging lines, utilizing the 100 mm stroke to redirect products efficiently without excessive cycle times.
Material Ejection
Drives short-stroke ejection pins to remove stamped or molded components from press beds, taking advantage of the robust SUS420J2 rod material.
Is the Airtac SAI50 Standard Cylinder SAI50AX100 the Right Cylinder?
Select this 50 mm bore when an application requires stepping up from the 40 mm class, which only yields 628 N at 0.5 MPa. If your system demands precise end-of-stroke feedback, you would need to specify the -S magnet option and add CMSE or DMSE sensors, as this base configuration omits the magnetic ring.
Because this is a standard double-acting cylinder, it relies entirely on continuous air pressure to maintain its rod position. If the air supply drops or the valve centers, the piston will drift. For suspended loads that require safety holding without live pressure, integrate the SAIL variant with an air-released lock. As a true ISO 15552 profile cylinder, it drops directly into standardized mounting footprints using FA or FB flanges, TC trunnions, 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 SAI50AX100 FAQ
At an operating pressure of 0.5 MPa, this 50 mm bore cylinder generates 982 N of push force and 825 N of pull force. If pressure is increased to 0.7 MPa, the push force rises to 1374 N.
Yes, the SAI50X100 is dimensionally interchangeable per ISO 15552. You can swap it directly into existing mounts using standard FA flanges or TC trunnions, provided your system uses the PT G1/4 port.
