About the Airtac SE40 Standard Cylinder SE40BX40S
The AirTAC SE40BX40S is a double-acting single-rod profile cylinder built to ISO 15552 standards, delivering 628 N of push force at 0.5 MPa. It features a SUS304 stainless steel piston rod specifically engineered for corrosive environments and washdown duty. The square extruded aluminum barrel eliminates external tie rods, yielding a compact footprint that mounts flush against machine frames while resisting external corrosion.
Equipped with a built-in position magnet, this unit interfaces directly with AirTAC CMSE reed and DMSE electronic sensors for precise end-of-stroke detection. The field-adjustable pneumatic cushioning at both ends allows technicians to tune deceleration via a set screw, softening hard mechanical impacts during rapid 30-800 mm/s cycling without acting as a physical lock.

Where the Airtac SE40 Standard Cylinder SE40BX40S Is Used
Lab Diagnostic Carousel
Drives a 40 mm stroke rotary indexing carousel in analytical equipment, using the SUS304 rod to resist chemical reagent splashes during testing cycles.
Pouch Sealing Press
Applies 628 N of clamping force at 0.5 MPa to seal medical pouches, relying on the adjustable end cushions to prevent shock at high cycling speeds.
Stainless Parts Ejector
Ejects machined stainless fittings from a CNC lathe, where the standard aluminum body and SUS304 rod survive coolant mist without binding.
Is the Airtac SE40 Standard Cylinder SE40BX40S the Right Cylinder?
Selecting this 40 mm bore provides 628 N push at 0.5 MPa, sitting neatly between the smaller 32 mm bore (402 N push) and the larger 50 mm bore (982 N push). If your payload demands less force, step down to the 32 mm; if you need heavier clamping, step up to the 50 mm. This model uses a PT1/4 port and includes the -S magnet for CMSE/DMSE position sensing.
Because it is a standard double-acting cylinder, it will drift if air pressure is lost or the valve centers, so it cannot hold a load safely without live pressure—use a BSE rod lock for fail-safe holding. As a true ISO 15552 profile cylinder, it serves as a direct dimensional replacement for comparable ISO 15552 cylinders, sharing standard mounting accessories like FA front flanges or LB foot brackets.
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 SE40BX40S FAQ
At 0.5 MPa, this 40 mm bore cylinder provides 628 N push and 528 N pull. At 0.7 MPa, the push force is 879 N. The maximum push force is 128 kgf at 1.0 MPa, with an operating speed range of 30-800 mm/s.
Yes, the SE40BX40S is dimensionally interchangeable with any standard ISO 15552 profile cylinder. It shares the same mounting interface and PT1/4 port size, allowing you to reuse existing FA flanges or LB foot brackets without redesigning the machine.
