About the Airtac SAI40 Standard Air Cylinder SAI40AX160
The AirTAC SAI40X160 is a double-acting ISO 15552 profile cylinder engineered to deliver 879 N of push force at 0.7 MPa. Its 160 mm stroke provides the extended travel needed for mid-range automation tasks. The extruded aluminum barrel design omits traditional tie rods, ensuring a clean exterior that resists debris accumulation.
Built to exacting standards, this specific configuration features a SUS420J2 stainless steel piston rod (material code A) for superior corrosion resistance in humid environments. It utilizes PT tapered port threads and lacks a standard magnet, meaning position sensing is handled externally unless modified.

Where the Airtac SAI40 Standard Air Cylinder SAI40AX160 Is Used
Component Clamping
Provides reliable 879 N clamping force at 0.7 MPa for securing aluminum or steel workpieces during CNC machining operations.
Package Diverter
The 160 mm stroke actuates diverter arms swiftly to sort medium-weight packages on automated logistics conveyor lines.
Gate Control
Actuates access gates and process chamber doors where the SUS420J2 rod material prevents rust in washdown-adjacent zones.
Is the Airtac SAI40 Standard Air Cylinder SAI40AX160 the Right Cylinder?
Selecting this 40 mm bore unit makes sense when a 32 mm bore (offering 563 N push at 0.5 MPa) lacks power, but a 50 mm bore (982 N push at 0.5 MPa) would be physically oversized. The 160 mm stroke falls within standard parameters, but always verify side-load parameters if guiding heavy payloads.
Because this is a double-acting cylinder, it relies on continuous air pressure to hold position; the adjustable air cushions at both ends only decelerate the piston near stroke end and will not brake or lock the load. If your application requires fail-safe holding, consider the SAIL variant with an air-released lock. This model is dimensionally interchangeable per ISO 15552, featuring a 16 mm rod, G1/4 port, and M12x1.25 rod thread.
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.
