About the Airtac SAI40 Standard Air Cylinder SAI40AX175S
The AirTAC SAI40X175-S is a double-acting ISO 15552 profile cylinder engineered to deliver 628 N of push force at 0.5 MPa and 879 N at 0.7 MPa. Its 175 mm stroke provides the extended travel needed for mid-range positioning tasks. Built to a true ISO 15552 mounting interface, it serves as a direct replacement for other standard profile cylinders.
This specific configuration includes a SUS420J2 stainless steel piston rod (material code A) for enhanced corrosion resistance compared to standard carbon steel. It is equipped with a magnet (-S) for direct compatibility with CMSE and DMSE sensor switches, which seat neatly into the dual-side extruded barrel grooves. Fluid porting utilizes PT tapered threads sized at G1/4.

Where the Airtac SAI40 Standard Air Cylinder SAI40AX175S Is Used
Component Clamping
Provides 879 N of clamping force at 0.7 MPa to secure medium-sized metal parts during machining operations.
Package Diverting
Uses the 175 mm stroke to push cartons off a main conveyor belt into secondary packaging lanes.
Gate Actuation
Extends and retracts to control material flow gates in light industrial bulk handling systems.
Is the Airtac SAI40 Standard Air Cylinder SAI40AX175S the Right Cylinder?
Select this 40 mm bore when an application requires stepping up from the 32 mm class (which provides 402 N at 0.5 MPa) to handle heavier payloads without the bulk of a 50 mm cylinder. The 175 mm stroke is well within the 1200 mm standard limit, but at this length designers should verify side-load conditions to prevent premature rod-bearing wear.
Because the 175 mm stroke exceeds the 300 mm threshold where side-load guidance becomes critical, consider an external guide rail or a guided cylinder to absorb lateral forces. Note that the adjustable air cushions at both ends only decelerate the piston near stroke end; they do not hold the load if air pressure drops. For position holding without live pressure, specify the SAIL or BSAI variant. To match this cylinder, use the G1/4 PT port, an appropriate ISO 15552 mounting accessory (like an FA flange or LB foot), and ensure the -S magnet is specified for sensor feedback.
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 SAI40AX175S FAQ
At a standard operating pressure of 0.5 MPa, this 40 mm bore cylinder outputs 628 N of push force and 528 N of pull force. At 0.7 MPa, the push force increases to 879 N.
Yes. The SAI40X175-S is built to the ISO 15552 dimensional standard, making it dimensionally interchangeable with other ISO 15552 profile cylinders of the same bore and stroke. It is not a specific brand's part, but it matches the standard mounting interface.
