About the Airtac SAI32 Standard Cylinder SAI32X40
The AirTAC SAI32X40 is a double-acting ISO 15552 profile cylinder featuring a 32mm bore and 40mm stroke. It delivers 402N of push force at 0.5 MPa, making it well-suited for compact, lower-force routing and clamping tasks.
This model features a standard carbon steel piston rod and PT tapered port threads. The extruded aluminum barrel includes integrated sensor grooves on both sides, allowing you to easily add CMSE or DMSE switches if position feedback is required later.

Where the Airtac SAI32 Standard Cylinder SAI32X40 Is Used
Part Clamping
Ideal for securing small machined components during secondary milling or drilling operations within a 402N force range.
Package Diverting
Provides reliable actuation for lightweight diverter arms on packaging lines where a short 40mm stroke is sufficient.
Small Pressing
Executes low-tonnage pressing or insertion tasks, such as seating small bearings or pins on automated assembly machines.
Is the Airtac SAI32 Standard Cylinder SAI32X40 the Right Cylinder?
Choose this 32mm bore when your application requires around 402N of push force at 0.5 MPa; step up to the 40mm bore if you need 628N. As a true ISO 15552 profile cylinder, this SAI32X40 is dimensionally interchangeable with other ISO 15552 cylinders. To match this exact unit, specify a 32mm bore, 40mm stroke, PT port thread, and your required mounting accessory (like an LB foot or FA flange).
Note that a standard SAI does not hold its load when air pressure is removed; the piston will drift if the valve is centered or pressure is lost. If your application requires position holding without live pressure, consider the SAIL lock or BSAI clamp-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 SAI32 Standard Cylinder SAI32X40 FAQ
At an operating pressure of 0.5 MPa, the SAI32X40 generates 402N of push force, increasing to 563N at 0.7 MPa.
Yes, because it is a genuine ISO 15552 profile cylinder, it is dimensionally interchangeable with other ISO 15552 cylinders, allowing for a direct replacement using standardized mounting interfaces.
