About the Airtac SAI50 Standard Cylinder SAI50AX65S
The AirTAC SAI50X65-S is a double-acting ISO 15552 profile cylinder built with a 50mm bore and a 65mm stroke. It generates 982 N of push force at 0.5 MPa, making it well-suited for medium-duty handling tasks that require short, precise movements.
This variant includes a magnet for CMSE and DMSE sensor switches and uses a SUS420J2 stainless steel piston rod. The extruded aluminum barrel features sensor grooves on both sides, and the PT tapered port ensures a reliable, leak-free pneumatic connection.

Where the Airtac SAI50 Standard Cylinder SAI50AX65S Is Used
Short-Stroke Clamping
Ideal for holding parts securely in machining fixtures using its 982 N push force over a compact 65mm travel.
Package Diverting
Provides rapid actuation for sorting gates on packaging lines, utilizing the 30-800 mm/s speed range.
Material Push-Off
Efficiently ejects molded parts or light scrap from machinery bases within a tight 65mm spatial footprint.
Is the Airtac SAI50 Standard Cylinder SAI50AX65S the Right Cylinder?
If your application requires slightly less force, stepping down to the 40mm bore yields 628 N at 0.5 MPa, while the 63mm bore offers 1559 N for heavier loads. Because this 65mm stroke is relatively short, rod-bearing bending is minimal, but always mount within the ISO 15552 interface using an FA flange or LB foot bracket.
Note that a standard SAI cylinder will drift if air pressure is lost. For vertical loads that must be held without live pressure, consider the SAIL variant with an air-released lock or 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.
Airtac SAI50 Standard Cylinder SAI50AX65S FAQ
