About the Airtac SAI40 Standard Air Cylinder SAI40BX175S
The AirTAC SAI40X175-S is a double-acting ISO 15552 profile cylinder featuring a 40mm bore and 175mm stroke. It delivers 628 N of push force and 528 N of pull force at 0.5 MPa, making it well-suited for medium-duty handling tasks. The extruded aluminum barrel design omits tie rods for a clean exterior.
This specific configuration includes a SUS304 stainless steel piston rod (material code B) for superior corrosion resistance in wet or chemically exposed environments. It is equipped with a magnet (-S) for position sensing using CMSE or DMSE switches along the dual sensor grooves, and features PT tapered port threads.

Where the Airtac SAI40 Standard Air Cylinder SAI40BX175S Is Used
Material Handling
Drives package diverters and medium-load pushers on automated conveyor lines with precise 175mm strokes.
Assembly Automation
Actuates medium-force clamping and pressing fixtures where repeatable positioning is required.
Packaging Equipment
Moves folding arms and sealing jaws reliably in continuous-duty packaging machinery.
Is the Airtac SAI40 Standard Air Cylinder SAI40BX175S the Right Cylinder?
If your application requires less force, the 32mm bore offers 402 N at 0.5 MPa, while the 50mm bore provides 982 N for heavier loads. At a 175mm stroke, side loading can accelerate rod-bearing wear, so utilizing a guided cylinder or external slide rail is recommended for optimal longevity.
This model is dimensionally interchangeable per ISO 15552, serving as a direct replacement for other ISO 15552 profile cylinders. It uses a G1/4 PT port and standard mounting accessories like FA or LB. Remember that the adjustable air cushions only decelerate the piston at end-of-stroke; to hold a load vertically without air pressure, select the SAIL locking variant.
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 SAI40BX175S FAQ
