About the Airtac SAI40 Standard Air Cylinder SAI40X195
The AirTAC SAI40X195 is a double-acting ISO 15552 profile cylinder engineered to deliver 628 N of push force at 0.5 MPa. Its 195 mm stroke provides the extended travel needed for mid-range positioning tasks. The extruded aluminum barrel design omits tie rods, ensuring a clean exterior that drops into standard ISO 15552 mounting footprints.
This configuration features a standard carbon steel piston rod and PT tapered port threads. Because it lacks the -S magnet option, it is optimized for pure mechanical actuation rather than electronic position sensing. For high-temperature environments up to +70 C, the standard TPU seals handle typical demands, though Viton (H) alternatives exist for more extreme thermal loads.

Where the Airtac SAI40 Standard Air Cylinder SAI40X195 Is Used
Package Diverting
Provides the 628 N push force needed to actuate diverter arms on 40 mm stroke packaging lines.
Clamp Fixtures
Secures workpieces during machining operations using the full 195 mm travel to accommodate varying part sizes.
Gate Operation
Drives heavy access gates or safety barriers where a robust 40 mm bore profile cylinder is required.
Is the Airtac SAI40 Standard Air Cylinder SAI40X195 the Right Cylinder?
Select this 40 mm bore when a 32 mm bore (402 N push @ 0.5 MPa) is insufficient, but a 50 mm bore (982 N push @ 0.5 MPa) would be excessive. The 195 mm stroke approaches the threshold where side loads can stress the rod bearing. If your application involves lateral forces, utilize external guide rails or switch to a guided cylinder to prevent premature wear.
To match this exact unit, specify a 40 mm bore, 195 mm stroke, G1/4 PT port, and your desired mounting accessory like an LB foot or FA flange. Because a standard SAI exhausts air to move, it cannot hold a load if pressure drops; use the SAIL variant with an air-released lock for fail-safe positioning.
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 SAI40X195 FAQ
At 0.5 MPa operating pressure, the SAI40X195 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 SAI40X195 is dimensionally interchangeable per ISO 15552. It serves as a drop-in replacement for other ISO 15552 profile cylinders, matching standard mounting dimensions and G1/4 ports.
