About the Airtac SAI50 Standard Cylinder SAI50AX165S
The AirTAC SAI50X165-S is a double-acting ISO 15552 profile cylinder engineered to deliver 982 N of push force at 0.5 MPa. Its 165 mm stroke provides the precise mid-range travel needed for clamping, lifting, and indexing tasks. The extruded aluminum barrel omits traditional tie-rods, presenting a clean exterior that resists debris accumulation.
This specific configuration includes a factory-installed magnet (-S) for position detection via CMSE or DMSE reed switches seated in the dual sensor grooves. The piston rod is constructed from SUS420J2 stainless steel (material code A) for enhanced corrosion resistance, and air connections utilize PT tapered threads.

Where the Airtac SAI50 Standard Cylinder SAI50AX165S Is Used
Component Clamping
Provides reliable 982 N clamping force to secure aluminum or steel workpieces during CNC milling and drilling operations.
Package Diverting
Actuates routing gates on packaging lines, using the 165 mm stroke to push cartons smoothly into secondary processing lanes.
Material Ejection
Ejects molded parts from low-force assembly presses, utilizing the SUS420J2 stainless steel rod to withstand minor environmental moisture.
Is the Airtac SAI50 Standard Cylinder SAI50AX165S the Right Cylinder?
With an 825 N pull force at 0.5 MPa, this 50 mm bore is a solid step up from the 40 mm bore (528 N pull) for tasks needing moderate thrust without the bulk of a 63 mm cylinder. Because the 165 mm stroke is a non-standard increment, verify your exact end-of-stroke clearance.
For any stroke at or above 300 mm, you must manage side-load to prevent rod-bearing bending; however, at 165 mm, standard mountings (FA, FB, or LB) are generally sufficient. Remember that the adjustable air cushions only decelerate the piston at end-of-stroke; if the air supply drops, this cylinder cannot hold a load—consider the SAIL variant for pilot-operated locking.
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.
