About the Airtac SAI40 Standard Air Cylinder SAI40AX105
The AirTAC SAI40X105 is a double-acting ISO 15552 profile cylinder offering 628 N push force at 0.5 MPa and 879 N at 0.7 MPa. Its 105 mm stroke is well suited for short-travel clamping, gating, and mid-range automation tasks. The extruded aluminum barrel design omits tie rods, presenting a clean exterior that resists debris buildup in active work cells.
This specific configuration features a SUS420J2 stainless steel piston rod (material code A), providing excellent corrosion resistance for humid or mildly chemically exposed environments. It utilizes PT tapered port threads, and because no magnet is specified, it relies on external limit switches or standard positioning rather than internal reed sensors.

Where the Airtac SAI40 Standard Air Cylinder SAI40AX105 Is Used
Part Ejection
Provides 628 N of push force at 0.5 MPa to reliably knock finished parts out of machining fixtures.
Package Diverting
The 105 mm stroke actuates diverter arms swiftly on packaging lines, operating efficiently at speeds up to 800 mm/s.
Gate Control
The SUS420J2 stainless rod withstands washdown environments while opening and closing access gates on the factory floor.
Is the Airtac SAI40 Standard Air Cylinder SAI40AX105 the Right Cylinder?
Select this 40 mm bore when an application requires around 879 N of push force at 0.7 MPa. If your assembly needs less force, stepping down to the 32 mm bore yields 563 N at the same pressure, whereas moving up to the 50 mm bore provides 1374 N for heavier payloads. The 105 mm stroke offers a compact footprint while maintaining enough travel for robust part ejection.
As a true ISO 15552 cylinder, it serves as a direct dimensional replacement for other ISO 15552 profile cylinders. It uses a G1/4 port, an M12x1.25 rod thread, and 30 mm adjustable air cushions at both ends. Note that this standard cylinder will drift if air pressure is lost; use the SAIL variant with an air-released lock if your workflow demands fail-safe load holding.
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.
