About the Airtac SAI63 Standard Cylinder SAI63AX160
The AirTAC SAI63X160 is a double-acting ISO 15552 profile cylinder offering 1559 N of push force at 0.5 MPa. Its 160 mm stroke provides an optimal mid-range extension for automated clamping and lifting tasks. The extruded aluminum barrel omits tie-rods for a clean exterior.
This specific unit features a SUS420J2 stainless steel piston rod (material code A) for superior corrosion resistance over standard carbon steel. It uses PT tapered port threading (G3/8) and lacks a standard magnet, making it ideal for purely mechanical actuation without sensor requirements.

Where the Airtac SAI63 Standard Cylinder SAI63AX160 Is Used
Automated Clamping
Provides 1559 N of secure clamping force for machining and welding fixtures.
Material Diverting
Actuates diverter arms on packaging lines with a reliable 160 mm throw.
Parts Ejection
Pushes finished parts out of press dies with consistent force and speed.
Is the Airtac SAI63 Standard Cylinder SAI63AX160 the Right Cylinder?
Choose this 63 mm bore when 40 mm cylinders (628 N at 0.5 MPa) lack thrust or 80 mm units (2513 N) are physically oversized. The 160 mm stroke is a standard dimension, fitting seamlessly into ISO 15552 mounting footprints without custom machining.
If your process loses air pressure, the adjustable cushions on this cylinder will not hold the load. They only decelerate the piston near the end of stroke. For fail-safe position holding, 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.
