About the Airtac SE40 Standard Cylinder SE40BX300S
The AirTAC SE40BX300S is a double-acting single-rod ISO 15552 profile cylinder with a 40mm bore and 300mm stroke. It delivers 628 N of push force at 0.5 MPa and 879 N at 0.7 MPa. The SUS304 stainless steel piston rod is engineered for corrosive and washdown environments, preventing rust in food processing or chemical handling setups.
Unlike traditional tie-rod bodies, this cylinder uses a square extruded aluminum barrel that mounts flush against machine frames. The integrated magnet (-S) directly supports AirTAC CMSE reed and DMSE electronic position sensors, dropping into the three-sided sensor grooves for precise end-of-stroke detection.

Where the Airtac SE40 Standard Cylinder SE40BX300S Is Used
Chemical Dipper Arm
The SUS304 rod withstands corrosive vapors while pushing a 300mm dipper arm into chemical baths, relying on 628 N of force to lift heavy fluid-soaked parts.
Washdown Diverter
Drives a pop-up deflector gate on a food packaging line, using the integrated magnet with DMSE sensors to confirm gate position during high-pressure wash cycles.
CNC Lathe Unloader
Ejects finished metal bar stock from a CNC lathe spindle, utilizing the 30mm adjustable air cushion to soften the 300mm extension stroke at high speeds.
Is the Airtac SE40 Standard Cylinder SE40BX300S the Right Cylinder?
At 0.5 MPa, this 40mm bore generates 628 N of push force. If your application requires less force, the neighboring 32mm bore provides 402 N. If you need to step up for heavier loads, the 63mm bore offers 1559 N. Because this is a standard double-acting cylinder, it will drift and cannot hold a load if air pressure is lost or the valve is centered; use a BSE rod lock variant for fail-safe holding.
With a 300mm stroke, the 16mm rod and its bearing face higher bending moments under side loads. Always mount an external guide to support the payload and prevent rod distortion. For retrofitting, this model is dimensionally interchangeable per ISO 15552, uses a PT1/4 port, and accepts standard mounting accessories like FA front flanges.
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 SE40BX300S FAQ
At 0.5 MPa, the push force is 628 N and the pull force is 528 N. At 0.7 MPa, the push force is 879 N. The maximum push force is 128 kgf at 1.0 MPa.
Yes, the SE40BX300S is dimensionally interchangeable per ISO 15552, meaning it shares the exact mounting footprint and can serve as a direct replacement for other ISO 15552 profile cylinders. It uses a PT1/4 port and M12x1.25 rod thread.
