About the Airtac SE80 Standard Cylinder SE80X250SFTC
The AirTAC SE80X250SFTC is a double-acting, single-rod ISO 15552 profile cylinder engineered for heavy-duty pneumatics. It generates 2513 N of push force at 0.5 MPa and features a 250 mm stroke. The square extruded aluminum barrel omits external tie rods, yielding a compact, corrosion-resistant body that mounts flush against machine frames while protecting internal components.
This specific configuration includes a built-in magnet (-S) for non-contact position sensing via AirTAC CMSE reed or DMSE electronic switches. Field-adjustable air cushions at both ends allow technicians to tune end-of-stroke deceleration, softening hard mechanical stops during high-speed operations. The integrated FTC center trunnion mounting provides a pivoting anchor point for articulated mechanisms.

Where the Airtac SE80 Standard Cylinder SE80X250SFTC Is Used
Pallet Transfer Diverter
Utilizing the 2513 N push force and FTC trunnion mount, this cylinder smoothly pivots heavy timber pallets between parallel conveyor lines at high throughput speeds.
Injection Mold Ejection
The 250 mm stroke and adjustable air cushions provide the precise, soft end-of-stroke deceleration required when pushing finished plastic parts out of heavy injection molds.
Stamping Press Feed
Delivering 3518 N thrust at 0.7 MPa, this 80 mm bore unit feeds thick sheet metal blanks into a mechanical stamping press while the -S magnet tracks cycle completion.
Is the Airtac SE80 Standard Cylinder SE80X250SFTC the Right Cylinder?
Selecting this 80 mm bore yields 2513 N push at 0.5 MPa, striking a balance between the 63 mm bore (1559 N push) and the 100 mm bore (3927 N push). If your load demands less force, step down to the 63 mm; if you require heavier thrust, step up to the 100 mm. Remember that a plain SE cylinder will drift if air pressure is lost or the valve centers; for fail-safe load holding, consider the BSE rod lock variant instead of relying on the cushions, which only decelerate the piston near stroke end.
With a 250 mm stroke, the 25 mm rod and M20x1.5 thread handle substantial axial loads, but long unsupported strokes invite rod-bearing bending. Implementing an external guide rail prevents side-load damage and premature seal wear. This model uses a PT3/8 port and includes an FTC mounting accessory and an -S magnet for sensors.
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.
