About the Airtac SE40 Standard Cylinder SE40BX100S
The AirTAC SE40BX100S is a double-acting single-rod ISO 15552 profile cylinder engineered for demanding environments. It features a 40mm bore and a 100mm stroke, delivering 628 N of push force at 0.5 MPa and 879 N at 0.7 MPa. The extruded aluminum barrel omits external tie rods, yielding a compact, corrosion-resistant body that mounts flush against machine frames while leaving three sensor grooves fully exposed for rapid switch placement.
This specific configuration incorporates a SUS304 stainless steel rod (code B) for superior resistance to moisture and washdown chemicals, alongside a built-in magnet (code S) for position detection. The piston decelerates smoothly at both ends via a field-adjustable air cushion—simply turn the needle screw to tune the end-of-stroke damping for your specific load and speed. Operating at 30-800 mm/s, it uses a PT1/4 port and an M12x1.25 rod thread.

Where the Airtac SE40 Standard Cylinder SE40BX100S Is Used
Flow Wrapper Film Sealing
Drives the end-sealing jaw on a horizontal flow wrapper, utilizing the 628 N push force and SUS304 rod to withstand frequent machine washdowns in food packaging facilities.
Bottle Divert Gate
Actuates a sorting diverter arm on a bottling line, where the 100mm stroke and 30-800 mm/s speed rapidly redirect containers without stalling the conveyor flow.
CNC Lathe Door Aperture
Opens and closes the safety interlock door on a CNC lathe, relying on the adjustable air cushion to soften the 100mm stroke impact and the no-tie-rod profile for a compact footprint.
Is the Airtac SE40 Standard Cylinder SE40BX100S the Right Cylinder?
When sizing this 40mm bore cylinder, evaluate your thrust margin: if 628 N push at 0.5 MPa is excessive for your payload, step down to the 32mm bore offering 402 N. If your mechanism demands more power, the 63mm bore provides 1559 N. Because this is a double-acting cylinder, it will drift if air supply is lost or a valve centers—the internal cushion only decelerates the stroke near the end caps and does not lock the load; use a BSE rod lock for positive holding. As a dimensionally interchangeable ISO 15552 cylinder, it serves as a direct retrofit for other 40mm bore profile cylinders, matching the PT1/4 port, 100mm stroke, and standard mounting footprint exactly.
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 SE40BX100S FAQ
The 40mm bore generates 628 N push and 528 N pull at 0.5 MPa, 879 N push at 0.7 MPa, and a maximum of 128 kgf at 1.0 MPa. It operates at speeds of 30-800 mm/s.
