About the Airtac SE80 Standard Cylinder SE80X520S
The AirTAC SE80X520S is a double-acting single-rod ISO 15552 profile cylinder engineered for demanding pneumatic tasks. It delivers a substantial 2513 N push force at 0.5 MPa, utilizing an 80 mm bore and a 520 mm stroke. The extruded aluminum barrel omits external tie rods, yielding a flush, corrosion-resistant exterior that simplifies mounting and keeps debris from accumulating on the body.
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 tune end-cap deceleration via a setscrew, softening hard mechanical stops during high-speed operations. Note that the 520 mm stroke is a non-standard, made-to-order length exceeding the 1500 mm standard maximum for this bore.

Where the Airtac SE80 Standard Cylinder SE80X520S Is Used
Pallet Transfer Line Diverter
Uses the 2513 N push force to deflect heavy wooden pallets onto a secondary roller conveyor, relying on the 520 mm stroke to clear the main transport lane completely.
Corrugated Box Flap Folder
Employs the 520 mm travel to fold large corrugated cardboard flaps on industrial cartoners, while the -S magnet triggers DMSE sensors to verify the fold completed before taping.
Injection Mold Ejector Gate
Actuates a heavy safety gate over an injection molding machine, utilizing the 3518 N push at 0.7 MPa to overcome the door's substantial mechanical weight and friction.
Is the Airtac SE80 Standard Cylinder SE80X520S the Right Cylinder?
Selecting this 80 mm bore makes sense when your application requires the 2513 N push at 0.5 MPa or 3518 N at 0.7 MPa. If your load is lighter, stepping down to the 63 mm bore yields a 1559 N push, whereas upgrading to the 100 mm bore provides a 3927 N push for heavier dynamics. Because the 520 mm stroke is non-standard, expect a made-to-order lead time. At 520 mm of travel, the 25 mm rod and its M20x1.5 thread face significant bending moments under side loads; always incorporate an external guide rail to prevent premature rod-bearing wear.
As a true ISO 15552 profile cylinder, it is dimensionally interchangeable with other ISO 15552 cylinders, allowing drop-in retrofits using existing mounting hardware like FA front flanges or TC center trunnions. Remember that the adjustable air cushion only decelerates the piston near the stroke ends—it does not lock or hold the load. If power or air is lost, the rod will drift; use a BSE rod lock variant for fail-safe position holding.
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 SE80X520S FAQ
This 80 mm bore cylinder uses a PT3/8 port. At 0.5 MPa it provides 2513 N of push force and 2268 N of pull force. At 0.7 MPa the push force is 3518 N. The maximum allowable push force is 513 kgf when operated at the 1.0 MPa pressure limit.
