About the Airtac SAI40 Standard Air Cylinder SAI40X190S
The AirTAC SAI40X190-S is a double-acting ISO 15552 profile cylinder engineered to deliver 628 N of push force at 0.5 MPa. Its 190 mm stroke is well-suited for mid-range linear actuation tasks. Because this variant includes a magnet (-S), it operates seamlessly with CMSE and DMSE sensor switches mounted into the dual side grooves of the extruded aluminum barrel.
For demanding environments, you can configure the standard carbon steel rod with NBR seals to handle standard operating temperatures, while maintaining the standardized ISO 15552 mounting dimensions for seamless integration.

Where the Airtac SAI40 Standard Air Cylinder SAI40X190S Is Used
Package Diverting
Provides the 628 N push force needed to actuate routing gates on 40 mm bore packaging lines.
Clamp Actuation
Extends 190 mm to secure mid-sized workpieces during light machining or assembly processes.
Material Stopper
Uses the integrated magnet to trigger DMSE sensors, confirming retraction before pallet transit.
Is the Airtac SAI40 Standard Air Cylinder SAI40X190S the Right Cylinder?
If your application requires slightly less force, stepping down to a 32 mm bore yields 402 N at 0.5 MPa. Conversely, upgrading to a 50 mm bore increases thrust to 982 N at 0.5 MPa. Since this model features a 190 mm stroke, standard mounting accessories like FA or FB flanges provide rigid support without excessive rod overhang.
This cylinder uses PT tapered port threads and a G1/4 connection. If your machinery loses air pressure, the piston will drift and cannot hold a load; for position-holding requirements, consider the SAIL variant with an air-released lock or an external pilot check valve.
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.
