About the Airtac SE80 Standard Cylinder SE80X550
The AirTAC SE80X550 is a double-acting single-rod ISO 15552 profile cylinder engineered for heavy-duty linear motion. Operating at 0.5 MPa, it generates 2513 N of push force and 2268 N of pull force, scaling up to a maximum output of 513 kgf at 1.0 MPa. The 80 mm bore pairs with a 550 mm stroke and a PT3/8 port to deliver robust actuation for demanding industrial cycles.
This unit utilizes a square extruded aluminum barrel without external tie rods, yielding a compact, corrosion-resistant body that mounts flush against machine frames. Field-adjustable air cushioning at both ends allows technicians to tune end-of-stroke deceleration via a set screw, softening hard impacts when moving heavy loads at speeds up to 800 mm/s. This specific SKU is built without a position sensor magnet, relying on external physical stops or limit switches for end-position confirmation.

Where the Airtac SE80 Standard Cylinder SE80X550 Is Used
Pallet Diverting Gate
Actuates a heavy diverter arm on a 1200 mm wide roller conveyor, using the 2513 N push force at 0.5 MPa to reliably shift loaded pallets onto a side spur without stalling.
Injection Mold Ejection
Drives a secondary ejection plate on a 200-ton injection molding machine, utilizing the 550 mm stroke to clear deep mold cavities and extract finished plastic automotive interior panels.
Corrugated Box Compression
Applies top-down holding pressure on a case erector to square up large corrugated cartons before tape application, relying on the 80 mm bore's stable thrust profile across the long travel.
Is the Airtac SE80 Standard Cylinder SE80X550 the Right Cylinder?
Selecting the SE80X550 is appropriate when your application requires substantial thrust within a 550 mm travel distance. If you need to scale down, the 63 mm bore neighbor provides 1559 N of push at 0.5 MPa; if you need to step up for higher load capacity, the 100 mm bore delivers 3927 N at the same pressure. Because this is a 550 mm stroke, the 25 mm rod and internal bearing face bending moments under side loading—an external guide rail is strongly recommended to prevent premature seal wear. As a standard ISO 15552 profile cylinder, this model serves as a drop-in replacement for other ISO 15552 cylinders, matching standardized mounting dimensions and port locations (PT3/8) for straightforward retrofits. Note that the adjustable air cushion only decelerates the piston near stroke end; it is not a locking device, so the cylinder cannot hold a vertical load if air pressure is lost.
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 SE80X550 FAQ
At 0.5 MPa, the SE80X550 delivers 2513 N of push force and 2268 N of pull force. At 0.7 MPa, the push force increases to 3518 N. The maximum push force is 513 kgf at 1.0 MPa. The cylinder operates at speeds ranging from 30 to 800 mm/s.
No, the SE80X550 is a standard double-acting cylinder and will drift if air pressure is lost or the valve is centered. The adjustable air cushion at both ends only decelerates the piston near the end of the stroke; it does not act as a brake or lock. For position holding, an external rod lock or pilot-operated check valve is required.
