About the Airtac SE40 Standard Cylinder SE40BX350S
The AirTAC SE40BX350S is a double-acting single-rod profile cylinder built to the ISO 15552 standard, delivering 628 N of push force at 0.5 MPa. It features a 40 mm bore, a 350 mm stroke, and a SUS304 stainless steel piston rod engineered for corrosive or washdown environments. The square extruded aluminum barrel omits external tie rods, yielding a compact footprint that mounts flush against machine frames while resisting contamination buildup.
Equipped with a built-in magnet (S code), this unit supports AirTAC CMSE reed and DMSE electronic sensors for precise end-position detection. The field-adjustable air cushioning at both ends allows technicians to tune the end-of-stroke deceleration via a set screw, softening hard impacts when cycling at speeds up to 800 mm/s.

Where the Airtac SE40 Standard Cylinder SE40BX350S Is Used
Bottling Line Diverter
Uses the 350 mm stroke and 879 N thrust at 0.7 MPa to push PET bottles between processing lanes, with the SUS304 rod enduring daily washdowns.
Pouch Forming Sealer
Drives the sealing jaw on vertical form-fill-seal equipment, relying on the 628 N extend force to crimp packaging film consistently.
Lab Sample Ejector
Ejects processed test tubes from chemical analyzers where the stainless steel rod prevents corrosion from reagent exposure.
Is the Airtac SE40 Standard Cylinder SE40BX350S the Right Cylinder?
When sizing this actuator, compare its 628 N push at 0.5 MPa against adjacent bores: the 32 mm version yields 402 N, while the 50 mm steps up to 982 N. This 40 mm bore fits perfectly when the smaller unit lacks thrust or the larger one is physically too wide. Because the stroke is 350 mm, the 16 mm rod and rod-bearing face increased bending moments under side loads—always incorporate an external guide rail to prevent premature seal wear.
As a dimensionally interchangeable ISO 15552 cylinder, it serves as a direct replacement for other ISO 15552 profile cylinders, matching the PT1/4 port and standard mounting accessories. Note that the adjustable air cushion only decelerates the piston near stroke end; it is not a locking device. If the machinery must hold a vertical load without live air pressure, specify a BSE rod lock variant instead.
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 SE40BX350S 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 is 879 N. The maximum push force is 128 kgf when operated at the 1.0 MPa pressure limit.
Yes. The SE40BX350S is dimensionally interchangeable per ISO 15552, meaning it shares the exact mounting footprint, PT1/4 port size, and 16 mm rod thread of other standard profile cylinders, allowing a direct retrofit.
