About the Airtac SE80 Standard Cylinder SE80AX950S
The AirTAC SE80AX950S is a double-acting single-rod profile cylinder built to the ISO 15552 standard, delivering a robust 2513 N push force at 0.5 MPa. Its square extruded aluminum barrel eliminates external tie rods, yielding a compact, corrosion-resistant body that mounts flush against machine frames. This clean profile is ideal for washdown environments, further enhanced by the SUS420J2 stainless steel rod (code A) which resists rust and chemical exposure.
Equipped with a built-in position magnet (-S), this unit interfaces directly with AirTAC CMSE reed and DMSE electronic sensors for precise end-of-stroke detection. The field-adjustable pneumatic cushioning at both ends allows technicians to tune deceleration via a set screw, softening hard impacts when cycling heavy loads at speeds up to 30-800 mm/s.

Where the Airtac SE80 Standard Cylinder SE80AX950S Is Used
Pallet Diverting Gate
Actuates a heavy diverting arm on a packaging line, using the 2513 N push force at 0.5 MPa to reliably redirect loaded pallets onto a secondary spur track.
Injection Mold Ejection
Drives a secondary ejection platen in an injection molding cell, where the 950 mm stroke extracts deep-draw parts and the SUS420J2 rod withstands residual mold release sprays.
Case Pusher Assembly
Pushes corrugated shipping cases into a sealing station, relying on the 36 mm adjustable cushion to smoothly stop the 80 mm bore at high speeds without jarring the contents.
Is the Airtac SE80 Standard Cylinder SE80AX950S the Right Cylinder?
Selecting this 80 mm bore makes sense when substantial thrust is required but you want to avoid the bulk of a 100 mm cylinder, which offers 3927 N push at 0.5 MPa. If your application is lighter, stepping down to a 63 mm bore yields 1559 N push. Because this model features a 950 mm stroke, the extended 25 mm rod and M20x1.5 thread face significant bending moments under side loads; always pair it with an external guide rail to prevent premature bearing wear.
As a standard ISO 15552 profile cylinder, it serves as a drop-in replacement for any matching ISO 15552 unit, sharing identical mounting and PT3/8 port dimensions. Remember that the adjustable air cushion only decelerates the piston near stroke end—it does not hold the load. If air pressure drops, the rod will drift; for static holding, integrate an external rod lock or 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 SE80 Standard Cylinder SE80AX950S FAQ
At 0.5 MPa, this 80 mm bore cylinder provides 2513 N of push force and 2268 N of pull force. At 0.7 MPa, the push force increases to 3518 N, with a maximum push capacity of 513 kgf at 1.0 MPa. The operational speed range is 30-800 mm/s.
Yes, the SE80AX950S is dimensionally interchangeable per ISO 15552. You can drop it in as a replacement for other 80 mm ISO 15552 profile cylinders, matching the standard mounting footprint and PT3/8 port. The built-in -S magnet also works seamlessly with AirTAC CMSE and DMSE sensors.
