About the Airtac SE100 Standard Air Cylinder SE100BX40
The AirTAC SE100BX40 is a double-acting single-rod ISO 15552 profile cylinder engineered for heavy-duty actuation, delivering a robust 3927 N push force at 0.5 MPa. This SKU features a SUS304 stainless steel piston rod (code B), making it highly suitable for corrosive environments and washdown applications where standard carbon steel rods would degrade.
Its square extruded aluminum barrel eliminates external tie rods, yielding a compact footprint that mounts flush against machine frames while resisting corrosion. The cylinder relies on a field-adjustable air cushion at both ends to decelerate the payload smoothly, and because this specific configuration lacks the internal sensor magnet, position verification requires external limit switches.

Where the Airtac SE100 Standard Air Cylinder SE100BX40 Is Used
Stamping Press Feeders
Drives heavy metal blanks into a forming press, utilizing the 3927 N push force at 0.5 MPa to overcome material resistance and seat the part accurately.
Pallet Dispenser Gates
Actuates the release mechanism on automated palletizer infeed conveyors, where the SUS304 rod withstands occasional washdowns and harsh cleaning chemicals.
Injection Mold Ejection
Provides the heavy thrust required to knock out large molded plastic parts from the tool cavity, benefiting from the 36 mm adjustable cushion to soften the end-of-stroke impact.
Is the Airtac SE100 Standard Air Cylinder SE100BX40 the Right Cylinder?
Selecting this 100 mm bore makes sense when your application demands substantial thrust; if you need to step down, the 80 mm bore yields 2513 N push at 0.5 MPa, whereas stepping up to the 125 mm bore provides 6136 N. This model carries a PT1/2 port and an M20x1.5 rod thread, interfacing seamlessly with standard ISO 15552 mounting accessories like FA front flanges or TC trunnions. Because the plain SE design lacks a rod lock, it cannot hold a vertical load without live air pressure—if your process requires true position holding upon air loss, consider the BSE variant or an external pilot-operated check valve.
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 SE100 Standard Air Cylinder SE100BX40 FAQ
At 0.5 MPa, this 100 mm bore cylinder provides 3927 N of push force and 3681 N of pull force. At 0.7 MPa, the push force increases to 5497 N, with an absolute maximum push capacity of 801 kgf at 1.0 MPa. It operates at speeds between 30-800 mm/s.
Yes, the SE100BX40 is dimensionally interchangeable per ISO 15552 standards, meaning it serves as a drop-in replacement for other ISO 15552 cylinders using standard mounting hardware. Note that this specific SKU does not have a built-in magnet, so it cannot host internal CMSE or DMSE sensors without modifying the piston assembly.
