About the Airtac SAI63 Standard Cylinder SAI63AX190S
The AirTAC SAI63X190-S is a double-acting ISO 15552 profile cylinder engineered to deliver 1559N of push force and 1402N of pull force at 0.5 MPa. Its 190mm stroke provides ample travel for mid-range automation tasks, while the extruded aluminum barrel design omits tie rods for a clean, compact exterior.
This specific configuration includes a factory-installed magnet (-S) for use with CMSE and DMSE sensor switches, which ride neatly in the dual-side barrel grooves. The piston rod is constructed from SUS420J2 stainless steel (code A) for superior corrosion resistance, and the PT tapered port threads ensure a reliable, leak-free pneumatic connection.

Where the Airtac SAI63 Standard Cylinder SAI63AX190S Is Used
Automated Clamping
Provides 1559N of thrust at 0.5 MPa for securely holding metal workpieces during machining or welding operations.
Product Diverting
Uses the 190mm stroke and integrated magnet to actuate sorting gates on high-speed packaging lines.
Material Ejection
Generates reliable push force to eject finished parts from molds or press beds in repetitive manufacturing cycles.
Is the Airtac SAI63 Standard Cylinder SAI63AX190S the Right Cylinder?
If your application requires less force, stepping down to a 50mm bore drops the 0.5 MPa push force to 982N, whereas a 80mm bore raises it to 2513N. Because this is a 190mm stroke, side-load stress on the rod bearing is minimal, but always ensure the load is axially aligned to prevent premature seal wear.
This model serves as a dimensionally interchangeable drop-in replacement for any standard ISO 15552 cylinder. To replicate this exact setup, match the 63mm bore, 190mm stroke, G3/8 PT port, and specify the -S magnet option along with an FA or LB mounting accessory. Note that the standard double-acting SAI does not hold loads when air pressure is removed; if your system needs fail-safe holding, consider the SAIL variant with an air-released lock.
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 SAI63 Standard Cylinder SAI63AX190S FAQ
