About the Airtac SAI40 Standard Air Cylinder SAI40BX170
The AirTAC SAI40X170 is a double-acting ISO 15552 profile cylinder featuring a 40mm bore and 170mm stroke. It delivers a push force of 628N at 0.5MPa and 879N at 0.7MPa, making it well-suited for medium-duty handling tasks.
This specific configuration incorporates a SUS304 stainless steel piston rod for superior corrosion resistance in humid or washdown environments. It uses tapered PT ports and lacks a standard magnet, but the extruded aluminum barrel still features dual-side sensor grooves ready for CMSE or DMSE switches if you add them later.

Where the Airtac SAI40 Standard Air Cylinder SAI40BX170 Is Used
Parts Clamping
Secures aluminum machined components on a milling station with 879N of push force at 0.7MPa.
Package Diverting
Actuates a routing arm on a packaging line to sort medium-weight cartons efficiently.
Pallet Stopping
Halts incoming pallets at a conveyor checkpoint using a reliable 170mm stroke length.
Is the Airtac SAI40 Standard Air Cylinder SAI40BX170 the Right Cylinder?
Select this 40mm bore when a 32mm cylinder (providing 402N push at 0.5MPa) lacks the necessary thrust for your fixture. If your application requires even less force, dropping down to a 32mm bore saves space. At 170mm of travel, the stroke is safely within standard limits, though side loads should still be minimized.
This model is dimensionally interchangeable per ISO 15552, serving as a direct replacement for other ISO 15552 profile cylinders. It features a G1/4 port, M12x1.25 rod thread, and is compatible with FA or LB mounting accessories. Because it is a standard double-acting cylinder, it will not hold a load if air pressure is lost; consider the SAIL variant for pneumatic locking requirements.
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.
