About the Airtac SE40 Standard Cylinder SE40BX250SFTC
The AirTAC SE40BX250SFTC is a double-acting single-rod profile cylinder built to ISO 15552 dimensions, delivering 628 N push at 0.5 MPa. It features a SUS304 stainless steel piston rod engineered for corrosive environments and washdown duty. The extruded aluminum barrel omits external tie rods, yielding a flush profile that simplifies mounting and resists debris buildup.
This 40mm bore unit includes a built-in magnet for CMSE reed and DMSE electronic position sensors. Field-adjustable air cushions at both ends allow you to tune end-of-stroke deceleration, protecting payloads from hard impacts. Operating at speeds of 30-800 mm/s, it utilizes a PT1/4 port and an M12x1.25 rod thread.

Where the Airtac SE40 Standard Cylinder SE40BX250SFTC Is Used
Bottle Rinser Gripper
Utilizes the SUS304 rod and 628 N push force to grip and invert containers through a washdown rinse cycle without rusting.
Flow Wrapper End-Seal Jaw
Cycles at high speed with DMSE electronic sensors to actuate packaging film sealing jaws, using adjustable cushions to soften impacts.
Diverter Gate Actuator
Leverages the 250mm stroke and FTC trunnion mount to pivot sorting gates on a stainless steel food processing conveyor line.
Is the Airtac SE40 Standard Cylinder SE40BX250SFTC the Right Cylinder?
This 40mm bore generates 628 N push at 0.5 MPa. If your application requires less force, the 32mm bore offers 402 N; if you need more clamping power, the 50mm bore provides 982 N. The SUS304 rod is specifically selected here over standard carbon steel to endure moisture and corrosive cleaning agents without pitting.
With a 250mm stroke, the M12x1.25 rod and internal bearing face increased bending moments under side loads, so fitting an external guide rail is recommended to prevent premature seal wear. Remember that the adjustable air cushion only decelerates the piston near stroke end; it does not hold the load if air pressure drops. For position holding, consider a BSE rod lock variant. This model uses an FTC center trunnion mounting accessory and is dimensionally interchangeable with other ISO 15552 cylinders.
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.
