About the Airtac SE40 Standard Cylinder SE40X90S
The AirTAC SE40X90S is a double-acting single-rod ISO 15552 profile cylinder engineered to deliver 628 N of push force at 0.5 MPa. Its square extruded aluminum barrel eliminates external tie rods, yielding a compact, corrosion-resistant body that mounts flush against machine frames. This clean profile design prevents dirt buildup while streamlining mechanical integration.
Equipped with a built-in magnet, this unit directly supports AirTAC CMSE reed and DMSE electronic position sensors for precise end-of-stroke verification. The field-adjustable air cushioning at both ends allows technicians to tune deceleration via a set screw, softening hard end stops during 90 mm travel. It is a true ISO 15552 dimensional interchange, meaning it drops seamlessly into existing standardized mounting hardware.

Where the Airtac SE40 Standard Cylinder SE40X90S Is Used
Carton Erection Arms
Provides the 628 N push force required to open and fold corrugated cardboard flaps on high-speed packaging lines, utilizing the 90 mm stroke for rapid cycling.
Package Diverters
Actuates routing gates on conveyor sortation systems, where the built-in magnet triggers DMSE sensors to confirm gate position before parcels arrive.
Small Part Ejectors
Pushes machined components out of CNC fixtures, using adjustable end cushions to prevent part marring during rapid ejection.
Is the Airtac SE40 Standard Cylinder SE40X90S the Right Cylinder?
Delivering 628 N push at 0.5 MPa, this 40 mm bore sits perfectly between the 32 mm bore (402 N push) and the 50 mm bore (982 N push), allowing you to step down for lighter loads or up for heavier rigging. For this 90 mm stroke, side-loading is minimal, but the 16 mm rod and M12x1.25 thread handle standard lateral forces well. Remember that the adjustable air cushion only decelerates the piston near stroke end; it does not hold a load if air pressure drops. If your application requires dead-stop positioning without live pressure, consider the BSE rod lock variant. To retrofit, match the 40 mm bore, 90 mm stroke, PT1/4 port, and your specific mounting accessory.
Quick checklist
- ✓ Required force at your working pressure
- ✓ Stroke and mounting space
- ✓ Port/thread type (PT/G)
- ✓ Magnet (-S) for CMSE/DMSE 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 (LB/FA/FB/CA/CB/CR/TC/FTC/TCM1/TCM2).
- check Installation by qualified personnel per AirTAC docs.
Airtac SE40 Standard Cylinder SE40X90S FAQ
At 0.5 MPa, the SE40X90S provides 628 N push and 528 N pull. At 0.7 MPa, push increases to 879 N. The maximum push force is 128 kgf at 1.0 MPa.
