About the Airtac SE40 Standard Cylinder SE40BX400S
The AirTAC SE40BX400S is a double-acting single-rod profile cylinder built to the ISO 15552 standard. It features a 40mm bore and a 400mm stroke, generating 628 N of push force and 528 N of pull force at 0.5 MPa. The square extruded aluminum barrel omits external tie rods, yielding a compact, corrosion-resistant body that mounts flush against machine frames.
Equipped with a SUS304 stainless steel rod (code B), this unit is purpose-built for corrosive environments and washdown duty. The built-in magnet (code S) supports position sensing via CMSE reed or DMSE electronic switches. Furthermore, the field-adjustable air cushioning at both ends allows technicians to tune end-of-stroke deceleration via a set screw, softening hard impacts during high-speed cycling.

Where the Airtac SE40 Standard Cylinder SE40BX400S Is Used
Bottling Line Diverter
Sorts polyethylene terephthalate containers on a washdown conveyor, utilizing the 400mm stroke and SUS304 rod to withstand harsh chemical cleaning cycles.
Pouch Forming Pusher
Actuates sealing jaws with 628 N of push force at 0.5 MPa, relying on the DMSE electronic sensor to verify the 400mm extension before the cut cycle initiates.
Lab Sample Ejection
Extracts processed fluid racks from testing centrifuges, where the corrosion-resistant stainless rod prevents contamination from accidental reagent exposure.
Is the Airtac SE40 Standard Cylinder SE40BX400S the Right Cylinder?
This 40mm bore provides 628 N push at 0.5 MPa. If your application requires less force, the adjacent 32mm bore yields 402 N; stepping up to the 63mm bore provides a substantial 1559 N. Because the stroke is 400mm, the unsupported piston rod length increases bending moments under side loads—always incorporate an external guide to prevent rod-bearing wear. The PT1/4 port and M12x1.25 rod thread are standardized, making this a direct replacement for any ISO 15552 cylinder. Remember that the adjustable cushion only decelerates the piston near stroke end; it does not hold the load if air pressure is lost. For position holding, explore the BSE rod-lock variant.
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 SE40BX400S 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. The operational speed range is 30-800 mm/s.
Yes, the SE40BX400S is dimensionally interchangeable per ISO 15552. You can use your existing mounting hardware and drop it in as a replacement, provided your setup accommodates the PT1/4 port and M12x1.25 rod thread.
