About the Airtac SAI40 Standard Air Cylinder SAI40X145
The AirTAC SAI40X145 is a double-acting ISO 15552 profile cylinder featuring a 40mm bore and a 145mm stroke. Because 145mm falls outside the standard increments, it is manufactured as a non-standard stroke. It delivers 628N of push force and 528N of pull force at 0.5 MPa, making it well-suited for medium-duty positioning tasks.
This model incorporates a standard carbon steel piston rod and utilizes PT tapered port threads. The extruded aluminum barrel includes sensor grooves on both sides for CMSE or DMSE switches, though a magnet is not specified for this configuration. For higher temperature environments up to 70 C, the standard TPU seals can be swapped for Viton (H) alternatives.

Where the Airtac SAI40 Standard Air Cylinder SAI40X145 Is Used
Component Clamping
Secures medium-weight workpieces during machining operations, utilizing 628N of thrust at 0.5 MPa to hold parts firmly against fixture stops.
Package Diverting
Actuates routing gates on packaging lines, where the 145mm stroke provides the exact reach needed to redirect boxes without standard stroke excess.
Material Ejection
Pushes finished parts out of press dies, using the 879N available at 0.7 MPa to reliably eject metal or plastic components.
Is the Airtac SAI40 Standard Air Cylinder SAI40X145 the Right Cylinder?
Selecting this 40mm bore over the smaller 32mm variant increases your 0.5 MPa push force from 402N to 628N, providing extra thrust for heavier slides. If your application requires even greater power, stepping up to the 50mm bore yields 982N at the same pressure. Because the 145mm stroke is a custom length, ensure your machinery accommodates the exact extended dimensions.
The SAI40X145 is dimensionally interchangeable per ISO 15552, serving as a drop-in replacement for other ISO 15552 profile cylinders. It features a G1/4 port, an M12x1.25 rod thread, and 30mm cushions at both ends. Note that the adjustable air cushion only decelerates the piston near stroke end; it does not hold a load. If your setup must maintain position without live air pressure, consider the SAIL (air-released lock) or BSAI (clamp-lock) variants.
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 SAI40X145 FAQ
At an operating pressure of 0.5 MPa, the SAI40X145 generates 628N of push force and 528N of pull force. If the pressure is increased to 0.7 MPa, the push force rises to 879N.
Yes, the SAI40X145 is a genuine AirTAC profile cylinder built to the ISO 15552 standard. Its mounting interface dimensions are interchangeable with other ISO 15552 cylinders, allowing for seamless drop-in replacement.
