About the Airtac SAI40 Standard Air Cylinder SAI40X210S
The AirTAC SAI40X210-S is a double-acting ISO 15552 profile cylinder engineered to deliver 628 N of push force at 0.5 MPa. Its 210 mm stroke provides the extended travel needed for mid-range material handling and packaging tasks. As a genuine AirTAC component, it ensures reliable pneumatic performance.
This variant includes a built-in magnet for non-contact position sensing using CMSE or DMSE switches housed in the dual sensor grooves. The standard carbon steel piston rod offers robust durability for general industrial automation.

Where the Airtac SAI40 Standard Air Cylinder SAI40X210S Is Used
Package Sorting
Provides the 628 N push force and 210 mm travel needed to divert medium-weight parcels on automated distribution lines.
Clamp Fixtures
Extends to secure workpieces during CNC machining, using the integrated magnet to confirm clamping position to the PLC.
Product Ejection
Cycles rapidly at up to 800 mm/s to push finished components from conveyor belts into downstream packaging bins.
Is the Airtac SAI40 Standard Air Cylinder SAI40X210S the Right Cylinder?
Select this 40 mm bore when an application requires more thrust than a 32 mm bore (402 N at 0.5 MPa) but lacks the physical space for a 50 mm option (982 N at 0.5 MPa). Because the 210 mm stroke exceeds 300 mm is not met here, side-load management is less critical, but always ensure axial alignment to maximize seal life.
For drop-in compatibility, this cylinder matches the ISO 15552 mounting interface using PT tapered port threads (G1/4). It supports standard FA/FB flanges or LB foot mounts. Remember that the standard adjustable air cushions only decelerate the piston at stroke ends; they do not hold a load. If your system loses pressure, the rod will drift. Use a SAIL variant for pneumatic locking 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.
Airtac SAI40 Standard Air Cylinder SAI40X210S FAQ
At 0.5 MPa, this 40 mm bore cylinder provides 628 N of push force and 528 N of pull force. At 0.7 MPa, the push force increases to 879 N.
Yes. The SAI40X210-S is dimensionally interchangeable per ISO 15552. It shares the same mounting footprint and G1/4 port size as other standard profile cylinders, allowing direct replacement without machine modifications.
