About the Airtac SAI40 Standard Air Cylinder SAI40BX65
The AirTAC SAI40X65 is a double-acting ISO 15552 profile cylinder offering 628 N of push force at 0.5 MPa and 879 N at 0.7 MPa. Its 65 mm stroke is well-suited for compact clamping and short-travel automation tasks. The extruded aluminum barrel design omits tie rods, providing a clean exterior while maintaining strict dimensional interchangeability with other ISO 15552 cylinders.
This specific configuration features a SUS304 stainless steel piston rod (material code B) for superior corrosion resistance in humid or washdown environments. It utilizes PT tapered port threads, and because it lacks the -S magnet option, it is optimized for pure actuation without sensor feedback requirements.

Where the Airtac SAI40 Standard Air Cylinder SAI40BX65 Is Used
Compact Part Clamping
Provides 879 N of push force at 0.7 MPa, ideal for securely holding lightweight machined components during secondary operations.
Package Diverting
The 65 mm stroke offers rapid, short-travel movement to route small packages on a conveyor line without occupying excessive machine footprint.
Washdown Actuation
The SUS304 stainless steel rod resists moisture and corrosion, making it reliable for food processing or light washdown gating tasks.
Is the Airtac SAI40 Standard Air Cylinder SAI40BX65 the Right Cylinder?
Select this 40 mm bore when a 32 mm bore (402 N push at 0.5 MPa) is insufficient, but a 50 mm bore (982 N at 0.5 MPa) would be physically oversized. The 65 mm stroke provides just enough travel for tight positioning tasks. Because this standard variant lacks a magnet, position sensing is not possible without external switches; choose an -S coded cylinder if you require CMSE or DMSE sensors.
Remember that a standard SAI cylinder relies on live air pressure to maintain its position; it will drift if air is lost. The adjustable air cushions at both ends only decelerate the piston near the stroke ends and do not act as a locking mechanism. For direct compatibility, match the 40 mm bore, 65 mm stroke, PT G1/4 port, and mounting accessories like FA flange or LB foot brackets.
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 SAI40BX65 FAQ
At a 0.7 MPa operating pressure, this 40 mm bore cylinder generates 879 N of push force and 528 N of pull force. At 0.5 MPa, the push force is 628 N.
Yes. The SAI40X65 is a genuine AirTAC profile cylinder built to strict ISO 15552 mounting dimensions, making it a direct replacement for any brand's ISO 15552 cylinder with matching 40 mm bore and 65 mm stroke specifications.
