About the Airtac SE40 Standard Cylinder SE40AX250H
The AirTAC SE40AX250H is a double-acting, single-rod ISO 15552 profile cylinder engineered for demanding environments. It delivers a robust 628 N push force at 0.5 MPa, utilizing a 40 mm bore and 250 mm stroke. This specific configuration pairs a high-temperature Viton (FKM) seal, extending the operating thermal envelope from -20 to +150 C, with a SUS420J2 stainless steel piston rod for superior corrosion resistance in washdown settings.
The extruded aluminum barrel eliminates external tie rods, yielding a compact footprint that mounts flush against machine frames while resisting localized corrosion traps. Integrated field-adjustable air cushions at both stroke ends allow technicians to tune end-of-travel deceleration via a set screw, smoothly dampening the 30 mm cushion zone without relying on fixed rubber bumpers. Note that this SKU lacks a built-in magnet, so it cannot host CMSE or DMSE position sensors without modification.

Where the Airtac SE40 Standard Cylinder SE40AX250H Is Used
Medical Autoclave Doors
The Viton FKM seal survives 150 C steam sterilization cycles, while the SUS420J2 stainless rod resists moisture corrosion as it actuates autoclave chamber doors with 628 N of push force.
Hot-Melt Adhesive Presses
Leveraging the 250 mm stroke, this cylinder drives packaging applicators through high-temperature glue stations where standard TPU seals would degrade, ensuring consistent carton sealing.
Baking Oven Ejectors
The FKM seal withstands ambient radiant heat inside industrial baking lines, pushing baked goods out of molds using 879 N of thrust at 0.7 MPa without elastomer failure.
Is the Airtac SE40 Standard Cylinder SE40AX250H the Right Cylinder?
This 40 mm bore generates 628 N of push force at 0.5 MPa. If your assembly requires less thrust, stepping down to the 32 mm bore yields 402 N, whereas moving up to the 50 mm bore provides 982 N. Because the 250 mm stroke creates a long unsupported lever arm, side loads will induce bending moments on the M12x1.25 rod thread and front bearing cap; an external guide rail is strongly recommended to prevent premature wear. As a standard ISO 15552 cylinder, it serves as a direct dimensional replacement for equivalent profile cylinders, utilizing a PT1/4 port and basic mounting interface.
Keep in mind that a standard double-acting cylinder drifts when air pressure is removed or a valve centers; the adjustable cushion only decelerates the piston near stroke end and does not lock the load. If your application must hold a vertical load without live pressure, consider 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 SE40AX250H 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 increases to 879 N, with an absolute maximum push capacity of 128 kgf at 1.0 MPa. Operating pressure ranges from 0.15-1.0 MPa, and the speed range is 30-800 mm/s.
Yes, it is dimensionally interchangeable with any standard ISO 15552 profile cylinder, matching the 40 mm bore footprint and PT1/4 port. However, it is a double-acting cylinder, meaning it will drift if air is lost; the adjustable end cushions only decelerate motion and do not act as a holding brake.
