About the Airtac SE80 Standard Cylinder SE80X390S
The AirTAC SE80X390S is a double-acting, single-rod ISO 15552 profile cylinder engineered for heavy-duty pneumatics. It delivers 2513 N of push force at 0.5 MPa, scaling to 3518 N at 0.7 MPa. The extruded aluminum barrel omits external tie rods, yielding a smooth, compact body that resists corrosion and mounts flush against machine frames without protruding hardware.
Equipped with a built-in magnet (-S), this unit seamlessly interfaces with AirTAC CMSE reed and DMSE electronic sensors for precise end-of-stroke detection. The field-adjustable air cushioning at both ends allows technicians to fine-tune end-of-stroke deceleration via a screw, effectively softening hard mechanical stops during high-speed operations.

Where the Airtac SE80 Standard Cylinder SE80X390S Is Used
Palletizer Case Erector
Provides the 2513 N push force required to fold and seal heavy corrugated cardboard flaps on automated palletizing lines, utilizing the 390 mm stroke for deep reach.
Metal Stamping Ejector
Kicks stamped steel blanks out of a 150-ton press bed, relying on the adjustable pneumatic cushion to decelerate the 25 mm rod smoothly before the end cap.
Heavy Belt Tensioner
Maintains optimal tension on high-mass aggregate conveyor belts, using the integrated magnet to trigger DMSE sensors when the belt slack reaches its adjustment limit.
Is the Airtac SE80 Standard Cylinder SE80X390S the Right Cylinder?
When sizing this 80 mm bore actuator, evaluate your thrust requirements against its neighbors. If your application only requires 1559 N of push at 0.5 MPa, stepping down to the 63 mm bore saves space and air consumption. Conversely, if you need 3927 N at 0.5 MPa, step up to the 100 mm bore. As a standard ISO 15552 cylinder, this model serves as a drop-in dimensional replacement for any compliant ISO 15552 actuator, matching the 80 mm bore, 390 mm stroke, PT3/8 port, and standard mounting accessories.
Because the 390 mm stroke is substantial, the 25 mm rod and its bearing face significant bending moments under side loads. For long extensions, always incorporate an external guide rail to prevent premature seal wear and piston drift. Note that this cylinder relies on live air pressure to hold a load; if air is lost or the valve is centered, the piston will drift. For fail-safe holding, integrate a BSE rod lock.
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 SE80X390S FAQ
At 0.5 MPa, the SE80X390S 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, and the operational speed range is 30-800 mm/s.
No, the SE80X390S is a standard double-acting cylinder and cannot hold a load if air is lost or the valve is centered; the piston will drift. The adjustable air cushion only decelerates the piston near the stroke end and does not act as a brake. For secure position holding, consider the AirTAC BSE series with a rod lock.
