About the Airtac SAI40 Standard Air Cylinder SAI40BX180S
The AirTAC SAI40X180-S is a double-acting ISO 15552 profile cylinder featuring a 40mm bore and 180mm stroke. It delivers 628 N of push force at 0.5 MPa, making it well-suited for mid-range industrial handling tasks. The extruded aluminum barrel design omits tie rods, presenting a clean exterior that integrates seamlessly into modern automated machinery.
This specific configuration includes a SUS304 stainless steel rod for superior corrosion resistance in humid or washdown environments. It is equipped with PT tapered port threads and includes a built-in magnet (-S) for direct compatibility with CMSE and DMSE series proximity switches via the dual sensor grooves on the barrel.

Where the Airtac SAI40 Standard Air Cylinder SAI40BX180S Is Used
Component Clamping
Provides reliable 628 N clamping force at 0.5 MPa for securing machined parts during milling or drilling operations.
Package Diverting
The 180mm stroke offers precise actuation distance for routing medium-sized cartons on packaging and sorting lines.
Material Ejection
Utilizes adjustable end cushions to smoothly eject molded parts from automated presses without impact damage.
Is the Airtac SAI40 Standard Air Cylinder SAI40BX180S the Right Cylinder?
Choose this 40mm bore when an SAI32 (402 N push at 0.5 MPa) lacks the necessary thrust, but an SAI50 (982 N push at 0.5 MPa) would be physically oversized. For applications requiring position holding without continuous air pressure, remember that the standard adjustable air cushions only decelerate the piston at stroke ends; they do not lock the rod. For secure load holding upon pressure loss, specify the SAIL pneumatic lock or BSAI bidirectional clamp-lock variant. To replace an existing ISO 15552 cylinder, match the 40mm bore, 180mm stroke, PT G1/4 port, and mounting accessories like FA/FB flanges or LB foot brackets, and ensure the -S magnet is included if sensors are used.
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 SAI40BX180S FAQ
At a 0.5 MPa operating pressure, the SAI40X180-S generates 628 N of push force and 528 N of pull force. At 0.7 MPa, the push force increases to 879 N.
Yes, the SAI40X180-S is dimensionally interchangeable with other ISO 15552 profile cylinders. You can replace a competing brand by matching the 40mm bore, 180mm stroke, G1/4 port, and mounting interface.
