About the Airtac SE40 Standard Cylinder SE40BX40SH
The AirTAC SE40BX40SH is a double-acting ISO 15552 profile cylinder engineered for rigorous environments, delivering 628 N of push force at 0.5 MPa. It features a SUS304 stainless steel rod and a high-temperature FKM seal, expanding the operating temperature range up to 150 C for washdown or caustic duty. The square extruded aluminum barrel omits external tie rods, yielding a compact footprint that mounts flush against machine frames while resisting corrosion.
Equipped with a built-in position magnet, this unit seamlessly integrates with AirTAC CMSE reed and DMSE electronic sensors to track travel. Field-adjustable air cushioning at both end caps allows technicians to tune deceleration, softening hard impacts when cycling at speeds up to 30-800 mm/s. This is a true pneumatic cushion, designed solely to decelerate the piston near stroke end rather than hold a load.

Where the Airtac SE40 Standard Cylinder SE40BX40SH Is Used
Lab Bottle Capping
Applies precise 628 N downward force to seal pharmaceutical vials, utilizing the FKM seal to withstand chemical vapors during sterilization cycles.
Food Grade Diverter
Actuates routing gates on a packaging line, where the SUS304 rod prevents corrosion during daily high-pressure washdowns.
Hot Stamp Ejector
Pushes molded parts away from 150 C platens, relying on the 40 mm stroke and FKM high-temp compound to survive ambient radiated heat.
Is the Airtac SE40 Standard Cylinder SE40BX40SH the Right Cylinder?
Selecting this 40 mm bore makes sense when an application requires 628 N push at 0.5 MPa but cannot accommodate a larger body. If you need less force, stepping down to the 32 mm bore yields 402 N push; stepping up to the 50 mm bore provides 982 N push. Because this configuration uses a Viton FKM seal and a SUS304 rod, it is specifically built for high-temperature or corrosive environments where standard TPU seals and carbon steel rods would fail.
As a standard ISO 15552 cylinder, it serves as a direct replacement for any cylinder sharing that mounting interface, utilizing standard PT1/4 ports and an M12x1.25 rod thread. Note that a plain double-acting cylinder drifts when air pressure is lost or exhausted, so if your process must hold a vertical load without live pressure, integrate an external rod lock or 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 SE40BX40SH 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. The maximum drive force is 128 kgf when operated at the 1.0 MPa pressure limit.
Yes, the SE40BX40SH is dimensionally interchangeable per ISO 15552. You can drop it into existing mounting hardware matching that standard footprint, provided your setup accommodates the PT1/4 port thread and M12x1.25 rod-end connection.
