About the Airtac SAI50 Standard Cylinder SAI50AX100S
The AirTAC SAI50X100-S is a double-acting ISO 15552 profile cylinder with a 50mm bore and 100mm stroke. It delivers a push force of 982 N at 0.5 MPa, making it a robust choice for mid-range automation tasks. The extruded aluminum barrel design omits tie rods, providing a clean exterior that is dimensionally interchangeable per ISO 15552 standards.
This specific configuration includes a built-in magnet (-S) for use with CMSE or DMSE reed switches, utilizing the dual sensor grooves machined into both sides of the barrel. Additionally, the piston rod is constructed from SUS420J2 stainless steel (material code A), offering enhanced resistance to corrosion compared to standard carbon steel. Ports feature a PT tapered thread.

Where the Airtac SAI50 Standard Cylinder SAI50AX100S Is Used
Material Diversion
Actuates sorting gates on packaging lines with precise 100mm strokes and 982 N of thrust at 0.5 MPa.
Clamping Fixtures
Secures workpieces during machining operations, utilizing the SUS420J2 stainless steel rod for durability.
Press Operations
Drives light assembly presses and joining stations, benefiting from the integrated magnet for end-of-stroke confirmation.
Is the Airtac SAI50 Standard Cylinder SAI50AX100S the Right Cylinder?
If your application requires less force, stepping down to a 40mm bore yields 628 N at 0.5 MPa, while moving up to a 63mm bore provides 1559 N for heavier loads. At a 100mm stroke, side-load stress on the rod bearing is minimal, so standard mounting accessories like an FA flange or LB foot bracket are sufficient without needing external guidance.
Because this is a standard double-acting cylinder, it does not hold position when air pressure is removed. The adjustable air cushions at both ends only decelerate the piston near stroke limits. If your process requires the load to remain locked during a pressure drop, integrate the SAIL variant with an air-released lock or use 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.
