About the Airtac SE40 Standard Cylinder SE40BX75S
The AirTAC SE40BX75S is a double-acting single-rod profile cylinder built to ISO 15552 dimensions, delivering 628 N of push force at 0.5 MPa. It features a SUS304 stainless steel piston rod, making it highly suitable for corrosive environments or washdown applications where standard carbon steel rods would degrade.
The extruded aluminum barrel eliminates external tie rods, creating a compact footprint that mounts flush against machine frames. Equipped with a built-in magnet, this unit supports AirTAC CMSE reed and DMSE electronic sensors for precise end-of-stroke detection. The field-adjustable air cushioning at both ends allows you to fine-tune deceleration and soften hard end stops during operation.

Where the Airtac SE40 Standard Cylinder SE40BX75S Is Used
Lab Bottle Capping
Applies precise 628 N of downward force at 0.5 MPa to secure caps on laboratory reagent bottles, utilizing the SUS304 rod to resist chemical splashes.
Food Belt Diversion
Actuates a routing gate on a washdown food processing line, where the stainless steel rod prevents corrosion during high-pressure cleaning cycles.
Carton Flap Folding
Drives a mechanical arm to fold corrugated carton flaps at high speed, using the 30 mm adjustable cushion to prevent harsh impacts at the 75 mm stroke end.
Is the Airtac SE40 Standard Cylinder SE40BX75S the Right Cylinder?
When sizing this 40 mm bore, step down to a 32 mm cylinder if you only need 402 N of push at 0.5 MPa, or step up to a 50 mm bore if your application requires 982 N. This SE40BX75S is dimensionally interchangeable with other ISO 15552 cylinders, allowing a direct replacement using existing mounting hardware and PT1/4 ports.
Because this is a double-acting cylinder, it relies on continuous air pressure to hold a load; if air is lost or the valve is centered, the piston will drift. For tasks requiring position holding without live pressure, consider the BSE rod lock variant or an external pilot-operated check valve.
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 SE40BX75S FAQ
At 0.5 MPa, it provides 628 N of push force and 528 N of pull force. At 0.7 MPa, the push force is 879 N. The maximum push force is 128 kgf at 1.0 MPa.
Yes, the SE40BX75S is dimensionally interchangeable per ISO 15552 standards. You can use it as a direct replacement for other 40 mm bore profile cylinders, retaining your existing PT1/4 port connections and mounting brackets.
