About the Airtac SAI40 Standard Air Cylinder SAI40AX160S
The AirTAC SAI40X160-S is a double-acting ISO 15552 profile cylinder engineered with a 40mm bore and 160mm stroke. It provides a push force of 628N at 0.5 MPa and 879N at 0.7 MPa, making it well-suited for mid-range actuation tasks. The extruded aluminum barrel design omits tie-rods, ensuring a clean exterior that drops directly into standard ISO 15552 mounting footprints.
This specific configuration includes an integrated magnet (-S) for use with CMSE and DMSE sensor switches, which ride smoothly in the dual side grooves. Furthermore, the piston rod is constructed from SUS420J2 stainless steel (material code A), offering enhanced resistance to moisture and corrosion compared to standard carbon steel.

Where the Airtac SAI40 Standard Air Cylinder SAI40AX160S Is Used
Mid-Range Part Clamping
Ideal for securing machined components during milling or drilling, utilizing its 879N push force at 0.7 MPa to hold parts firmly against locators.
Package Diverting
Provides reliable actuation for diverting medium-weight packages on a conveyor line, with the 160mm stroke offering sufficient reach to clear adjacent belts.
Gate Control
Actuates safety gates or process doors in automated machinery, benefiting from the SUS420J2 stainless steel rod in environments with high humidity.
Is the Airtac SAI40 Standard Air Cylinder SAI40AX160S the Right Cylinder?
Select this 40mm bore when an application requires more power than a 32mm cylinder (which yields 402N at 0.5 MPa) but lacks the physical space for a 50mm unit (982N at 0.5 MPa). The 160mm stroke provides ample extension for indexing and clamping operations. Because the stroke is 160mm, it is approaching lengths where side loading becomes a concern; use external guide rails or a guided cylinder to prevent rod-bearing bending if the load is not perfectly axial.
As a double-acting cylinder, the SAI40X160-S requires continuous air pressure to hold its position and will drift if pressure is lost or the valve is centered. The adjustable air cushions at both ends decelerate the piston smoothly but do not function as a mechanical lock. For exact ISO 15552 direct replacement, match the 40mm bore, 160mm stroke, PT G1/4 port, and desired mounting accessories like FA flange or LB foot brackets.
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 SAI40 Standard Air Cylinder SAI40AX160S FAQ
