About the Airtac SE40 Standard Cylinder SE40AX225S
The AirTAC SE40AX225S is a double-acting single-rod profile cylinder built to the ISO 15552 / VDMA 24562 dimensional standard. It features a 40mm bore and a 225mm stroke, yielding 628 N of push force at 0.5 MPa and 879 N at 0.7 MPa. The square extruded aluminum barrel omits external tie rods, yielding a compact, corrosion-resistant body that mounts flush against machine frames.
This specific configuration includes a SUS420J2 stainless steel rod (code A) for corrosive or washdown environments, and a built-in magnet (code S) for position sensing. Field-adjustable pneumatic cushioning at both ends allows you to tune end-of-stroke deceleration via a set screw, softening hard impacts during high-speed cycling.

Where the Airtac SE40 Standard Cylinder SE40AX225S Is Used
Flow Wrapper Film Splicing
Drives the sealing and cutting head on a horizontal flow wrapper, using the 225mm stroke to splice packaging film rolls during continuous high-speed packaging operations.
Bottling Line Diverter Gate
Actuates a pneumatic diverter arm on a bottling conveyor, leveraging the SUS420J2 stainless rod to withstand frequent washdowns while pushing containers at 628 N.
CNC Lathe Bar Feeder
Indexing mechanism in a CNC lathe bar feeder that pushes raw material into the collet, relying on the adjustable cushion to prevent mechanical shock at 800 mm/s.
Is the Airtac SE40 Standard Cylinder SE40AX225S the Right Cylinder?
If 628 N of push at 0.5 MPa is excessive for your payload, the adjacent SE32X225S steps down to 402 N. Conversely, demanding jobs can step up to the SE50X225S, which provides 982 N. Because the 225 mm stroke exceeds the 40 mm bore's 120 mm standard limit, this unit is non-standard and made-to-order. At 225 mm of travel, the 16 mm rod and M12x1.25 thread handle moderate side loads, but an external guide is recommended if the load is heavy or off-center.
This cylinder serves as a direct replacement for any ISO 15552 cylinder sharing the 40mm bore, 225mm stroke, PT1/4 port, and basic mounting interface. Note that the adjustable air cushion only decelerates the piston near the stroke ends; it does not hold the load if air pressure drops. For position holding, consider a BSE rod lock 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 SE40 Standard Cylinder SE40AX225S 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 the 1.0 MPa operating pressure limit.
Yes, the SE40AX225S is dimensionally interchangeable with any ISO 15552 cylinder matching the 40mm bore, 225mm stroke, PT1/4 port, and basic mounting dimensions, allowing for a direct retrofit.
