About the Airtac SAI40 Standard Air Cylinder SAI40BX145S
The AirTAC SAI40X145-S is a double-acting ISO 15552 profile cylinder engineered to deliver 628 N of push force at 0.5 MPa. Its 145 mm stroke provides the precise mid-range extension needed for compact assembly automation. Built with a genuine extruded aluminum barrel, it drops directly into standardized ISO 15552 mounting interfaces.
This specific configuration includes a SUS304 stainless steel rod for superior corrosion resistance in wet or washdown environments. It is equipped with a magnet for position sensing using CMSE or DMSE switches, and utilizes PT tapered port threads.

Where the Airtac SAI40 Standard Air Cylinder SAI40BX145S Is Used
Component Clamping
Provides 528 N of pull force at 0.5 MPa to securely hold aluminum or steel blocks during CNC machining operations.
Package Diverting
Uses the 145 mm stroke to extend a diverting arm, routing small to medium packaging along a conveyor belt system.
Dispensing Heads
Actuates fluid dispensing nozzles with repeatable precision, utilizing the SUS304 rod to resist chemical exposure.
Is the Airtac SAI40 Standard Air Cylinder SAI40BX145S the Right Cylinder?
Select this 40 mm bore when an application requires stepping up from a 32 mm bore (402 N at 0.5 MPa) to achieve higher thrust without increasing the footprint to a 50 mm bore (982 N at 0.5 MPa). The 145 mm stroke is well within standard limits, keeping the unsupported rod length short enough to avoid significant deflection under normal axial loads.
If the machinery loses air pressure, this standard cylinder cannot hold its load and the piston will drift; for suspended loads requiring fail-safe holding, specify the SAIL variant with an air-released lock. To match this unit for an ISO 15552 replacement, ensure the stroke is 145 mm, the port is PT G1/4, and the appropriate mounting accessory (such as an LB foot or FA flange) is selected.
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 SAI40BX145S FAQ
At an operating pressure of 0.5 MPa, this 40 mm bore cylinder provides 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-S is dimensionally interchangeable per ISO 15552. It can serve as a direct replacement for other ISO 15552 profile cylinders with a 40 mm bore, 145 mm stroke, and G1/4 port.
