About the Airtac SE80 Standard Cylinder SE80X1250S
The AirTAC SE80X1250S 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 robust 25 mm piston rod with an M20x1.5 thread. Designed with an extruded aluminum barrel, the square profile entirely eliminates external tie rods, yielding a compact, corrosion-resistant body that mounts flush against machine frames.
This 1250 mm stroke unit includes a built-in magnet (-S) for seamless integration with AirTAC CMSE reed and DMSE electronic sensors. Field-adjustable pneumatic cushioning at both ends allows you to tune the end-of-stroke deceleration via a screw, softening hard impacts during high-speed 30-800 mm/s operations.

Where the Airtac SE80 Standard Cylinder SE80X1250S Is Used
Palletizer Case Pushing
Pushing filled cartons onto pallets at 2513 N push force, using the 1250 mm stroke to fully traverse a conveyor lane during the packaging sequence.
Automotive Welding Line
Indexing heavy welding fixtures along a 1250 mm path, leveraging the 80 mm bore's 3518 N thrust at 0.7 MPa to overcome guide friction.
Press Brake Ejection
Ejecting heavy formed metal panels from a press brake, where the M20x1.5 rod end threads securely attach to the ejection arm.
Is the Airtac SE80 Standard Cylinder SE80X1250S the Right Cylinder?
Providing 2513 N of push at 0.5 MPa, this 80 mm bore is a strong mid-range choice. If your application requires less force, the 63 mm bore offers 1559 N; conversely, stepping up to the 100 mm bore yields 3927 N. Because this is a standard 1250 mm stroke for the 80 mm series, it avoids made-to-order delays. At 1250 mm, the unsupported rod length introduces a high risk of rod-bearing bending under side loads; an external guide rail is strongly recommended to prevent premature seal wear.
As a true ISO 15552 profile cylinder, it serves as a drop-in replacement for any ISO 15552 cylinder, sharing identical mounting interface dimensions and PT3/8 port locations. Note that the adjustable air cushion only decelerates the piston near the stroke end and does not hold the load; if air pressure is lost, the cylinder drifts. For position holding, 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 SE80 Standard Cylinder SE80X1250S FAQ
