About the Airtac SAI40 Standard Air Cylinder SAI40BX145
The AirTAC SAI40X145 is a double-acting ISO 15552 profile cylinder engineered to deliver 628 N of push force at 0.5 MPa, scaling up to 879 N at 0.7 MPa. Its 145 mm stroke is ideal for mid-range linear actuation tasks requiring consistent cycling. The extruded aluminum barrel design omits tie rods, providing a clean exterior that simplifies mounting and sensor placement.
This specific configuration features a SUS304 stainless steel piston rod for superior corrosion resistance in washdown or mildly chemically exposed environments. It utilizes PT tapered port threads and lacks a standard magnet, meaning position sensing via CMSE or DMSE switches is not supported unless specified otherwise. Adjustable pneumatic cushions at both stroke ends ensure quiet, impact-free operation.

Where the Airtac SAI40 Standard Air Cylinder SAI40BX145 Is Used
Parts Clamping
Provides reliable 628 N clamping force at 0.5 MPa for securing aluminum or composite components during CNC machining operations.
Package Diverting
Actuates sorting arms on packaging lines, utilizing the 145 mm stroke to push standardized cartons onto adjacent conveyor belts.
Gate Control
Operates lightweight access gates and machine guard doors, benefiting from the SUS304 rod's resistance to industrial humidity.
Is the Airtac SAI40 Standard Air Cylinder SAI40BX145 the Right Cylinder?
If your application requires less force, stepping down to the 32 mm bore yields 563 N at 0.7 MPa, whereas upgrading to the 50 mm bore provides 1374 N at 0.7 MPa for heavier loads. For this 145 mm stroke, side-loading is minimal, but always ensure rigid mounting using FA or FB flanges to prevent rod bearing wear.
Because this is a standard double-acting cylinder, it cannot hold a load if air pressure drops unexpectedly; the piston will drift. For position-holding safety, consider the SAIL pneumatic lock variant or an external rod lock. To match this unit for ISO 15552 interchangeability, specify a 40 mm bore, 145 mm stroke, PT G1/4 port, and SUS304 rod material.
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 SAI40BX145 FAQ
At a standard operating pressure of 0.5 MPa, this 40 mm bore cylinder 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 SAI40X145 is a true ISO 15552 profile cylinder, making its mounting interface dimensionally interchangeable with other ISO 15552 cylinders. Always confirm the G1/4 port and 145 mm stroke match your existing fixture.
