About the Airtac SE80 Standard Cylinder SE80X125
The AirTAC SE80X125 is a double-acting single-rod ISO 15552 profile cylinder engineered for robust linear motion. It generates 2513 N of push force and 2268 N of pull force at 0.5 MPa, utilizing a 25 mm hard-chrome rod with an M20x1.5 thread. The square extruded aluminum barrel eliminates external tie rods, yielding a compact footprint that resists corrosion and mounts flush against machine frames.
Field-adjustable pneumatic cushioning at both ends allows technicians to dial in end-of-stroke deceleration via a set screw, softening hard impacts when cycling at speeds up to 800 mm/s. Because this specific SKU lacks the -S magnet option, it is not equipped for CMSE or DMSE position sensing out of the box.

Where the Airtac SE80 Standard Cylinder SE80X125 Is Used
Palletizer Case Pusher
Provides 2513 N of push force at 0.5 MPa to index heavy corrugated cases onto palletizing lines, utilizing the 125 mm stroke for precise end-of-arm positioning.
Injection Mold Separation
Delivers the robust 2268 N pull force required to break vacuum and separate thick-walled injection molded plastic parts from heavy tooling dies.
Press Brake Backgauge
Drives the material stop on a sheet metal press brake, relying on the extruded profile barrel's rigid flush mounting to maintain alignment under high side-loading.
Is the Airtac SE80 Standard Cylinder SE80X125 the Right Cylinder?
This 80 mm bore hits a substantial 2513 N push at 0.5 MPa, sitting between the 63 mm bore (1559 N push) and the 100 mm bore (3927 N push) for sizing heavy loads. As a standard double-acting cylinder, it will drift if air pressure is lost or the valve centers; applications requiring true position holding without live pressure must integrate an external rod lock or pilot-operated check valve. To retrofit an existing fixture, match the 125 mm stroke, PT3/8 port, and ISO 15552 mounting interface for a seamless drop-in replacement.
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 SE80X125 FAQ
At 0.5 MPa, the SE80X125 generates 2513 N of push force and 2268 N of pull force. At 0.7 MPa, the push force reaches 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 SE80X125 is dimensionally interchangeable per ISO 15552 standards. You can swap it into existing mounting hardware using the standardized footprint, matching the 125 mm stroke, 25 mm rod, and PT3/8 port.
