About the Airtac SE80 Standard Cylinder SE80X125S
The AirTAC SE80X125S is a double-acting, single-rod ISO 15552 profile cylinder delivering a robust 2513 N push force at 0.5 MPa. Designed with a square extruded aluminum barrel, it eliminates protruding external tie rods, resulting in a compact, corrosion-resistant body that mounts flush against machine frames.
This 80 mm bore unit includes a built-in magnet (-S) for non-contact position sensing with AirTAC CMSE reed or DMSE electronic switches. Field-adjustable pneumatic cushioning at both ends allows you to fine-tune end-of-stroke deceleration via a set screw, protecting heavy moving loads from harsh impacts.

Where the Airtac SE80 Standard Cylinder SE80X125S Is Used
CNC Lathe Chuck Actuation
Provides the 2513 N push force required to actuate heavy-duty CNC lathe chucks, using the built-in magnet to confirm jaw grip via DMSE sensors.
Palletizer Case Pusher
Drives corrugated case diverters on palletizing lines, utilizing the 125 mm stroke and adjustable air cushions to soften end stops during high-speed cycling.
Injection Mold Platen Ejector
Ejects molded plastic parts from stationary platens, where the tie-rod-free extruded barrel withstands residual heat and prevents snagging on tooling.
Is the Airtac SE80 Standard Cylinder SE80X125S the Right Cylinder?
At 0.5 MPa, this 80 mm bore generates 2513 N of push force. If your application requires less thrust, stepping down to the 63 mm bore yields 1559 N, while stepping up to the 100 mm bore provides 3927 N. As a standard double-acting cylinder, the SE80X125S relies on continuous air pressure to hold a load; if air is lost or the valve centers, the piston will drift. For fail-safe position holding, consider the BSE rod-lock variant. This model uses a PT3/8 port and an M20x1.5 rod thread. Because this is an ISO 15552 profile cylinder, it serves as a dimensionally interchangeable drop-in replacement for other ISO 15552 cylinders without altering mounting footprints.
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 SE80X125S FAQ
The SE80X125S provides 2513 N of push force and 2268 N of pull force at 0.5 MPa. At 0.7 MPa, the push force increases to 3518 N. The maximum push force is 513 kgf when operating at the 1.0 MPa pressure limit.
Yes, the SE80X125S is dimensionally interchangeable per ISO 15552 standards. You can use it as a drop-in replacement for other ISO 15552 cylinders, reusing existing mounting hardware and maintaining the same PT3/8 port and M20x1.5 rod thread dimensions.
