Airtac SE80 Standard Cylinder SE80X420S
The AirTAC Airtac SE80 Standard Cylinder SE80X420S is a genuine double-acting ISO 15552 / VDMA 24562 profile-barrel air cylinder with a Ø80mm bore and 420mm stroke, PT3/8 air ports and adjustable end cushioning. Its standardized mounting interface makes it a drop-in replacement for other ISO 15552 cylinders in automation lines.

About the Airtac SE80 Standard Cylinder SE80X420S
The AirTAC SE80X420S is a double-acting single-rod profile cylinder built to the ISO 15552 standard, delivering a robust 2513 N push force at 0.5 MPa. Its square extruded aluminum barrel omits external tie rods, yielding a compact, corrosion-resistant body that mounts flush against machine frames while protecting internal pneumatics.
Equipped with a built-in magnet (-S), this unit triggers CMSE reed or DMSE electronic sensors for precise mid-stroke positioning. The field-adjustable air cushioning at both ends allows technicians to dial in end-of-stroke deceleration, absorbing the kinetic energy of a 420 mm travel span without jarring impacts.

Where the Airtac SE80 Standard Cylinder SE80X420S Is Used
Pallet Transfer Diverter
Leverages the 2513 N push force to deflect heavy timber pallets onto secondary packaging lines without stalling under high friction.
Corrugated Box Flap Folder
Uses the 420 mm stroke and DMSE electronic sensor feedback to sequence large carton folding arms at high cycling rates.
Injection Mold Platen Ejector
Deploys the 36 mm cushion length to gently decelerate the 25 mm rod as it pushes finished plastic parts clear of the mold cavity.
Is the Airtac SE80 Standard Cylinder SE80X420S the Right Cylinder?
This 80 mm bore strikes a balance between the 63 mm class (1559 N push @0.5 MPa) and the 100 mm class (3927 N push @0.5 MPa), letting you scale power up or down based on exact payload requirements. Because the 420 mm stroke generates significant leverage, an external guide is recommended to prevent rod-bearing bending under heavy lateral loads.
As a true ISO 15552 profile cylinder, it serves as a drop-in replacement for any standard 80 mm bore, 420 mm stroke unit with a PT3/8 port and matching mounting accessories. Note that the adjustable cushion only softens end stops; it cannot hold a load if air pressure drops, so integrate a BSE rod lock for fail-safe vertical 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 SE80X420S FAQ
The SE80X420S generates 2513 N push and 2268 N pull at 0.5 MPa, 3518 N push at 0.7 MPa, and a maximum push of 513 kgf at 1.0 MPa. It uses a PT3/8 port and a 25 mm rod with an M20x1.5 thread.
No, the adjustable air cushion only decelerates the piston near the stroke ends and does not function as a brake. If your application requires holding a load without live air pressure, you must use a BSE rod lock cylinder or an external pilot-operated check valve.
