About the Airtac SAI40 Standard Air Cylinder SAI40X180S
The AirTAC SAI40X180-S is a double-acting ISO 15552 profile cylinder featuring a 40mm bore and 180mm stroke. It delivers a push force of 628 N and a pull force of 528 N 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.
Equipped with a magnet (-S), this unit supports CMSE and DMSE sensor switches via the integrated grooves on both sides of the barrel. It comes standard with a carbon steel piston rod and utilizes PT tapered port threads for reliable pneumatic connections.

Where the Airtac SAI40 Standard Air Cylinder SAI40X180S Is Used
Package Routing
Diverts medium-weight cartons on a conveyor line using the 628 N push force and 180mm stroke to actuate routing arms.
Clamp Actuation
Secures workpieces in a CNC machining fixture, utilizing the integrated magnet and DMSE sensors to confirm clamp position.
Vertical Lifting
Raises lightweight pallets or totes in a compact sorting hub, taking advantage of the smooth profile barrel design.
Is the Airtac SAI40 Standard Air Cylinder SAI40X180S the Right Cylinder?
Select this 40mm bore when an application requires more thrust than a 32mm cylinder (402 N at 0.5 MPa) but does not warrant the bulk of a 50mm option (982 N at 0.5 MPa). The 180mm stroke provides ample extension for indexing and lifting tasks. Because the stroke is below 300mm, side-load stress on the rod bearing is moderate, though external guides should still be used for heavy off-center loads.
This cylinder serves as a dimensionally interchangeable drop-in replacement for other ISO 15552 cylinders. When ordering, confirm the 180mm stroke, G1/4 port, and desired mounting accessory (such as LB foot or FA flange). Note that a standard SAI does not hold position if air pressure is lost; for dead-load holding, consider the SAIL lock 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 SAI40X180S FAQ
At an operating pressure of 0.5 MPa, this 40mm bore cylinder provides a push force of 628 N and a pull force of 528 N. At 0.7 MPa, the push force increases to 879 N.
Yes, the SAI40X180-S is dimensionally interchangeable per ISO 15552 standards. It serves as a drop-in replacement for other ISO 15552 profile cylinders, provided the 40mm bore, 180mm stroke, and G1/4 port match your mounting interface.
