About the Airtac SE80 Standard Cylinder SE80X50SFA
The AirTAC SE80X50SFA is a double-acting single-rod ISO 15552 profile cylinder engineered to deliver a robust 2513 N push force at 0.5 MPa. Driven by a 25 mm hard-chrome piston rod, this 80 mm bore unit is built for demanding pneumatic circuits requiring significant thrust within a short 50 mm stroke.
Its square extruded aluminum barrel omits external tie rods, yielding a compact, corrosion-resistant body that mounts flush against machine frames. Equipped with a built-in magnet (-S) for CMSE reed or DMSE electronic position sensing, and a front flange (FA) for rigid face-mounting, it integrates seamlessly into high-cycle automated equipment.

Where the Airtac SE80 Standard Cylinder SE80X50SFA Is Used
Injection Mold Platen Clamping
Provides the 2513 N push force required to secure heavy injection mold platens, using the rigid FA front flange to withstand high axial shocks during part injection.
Heavy-Duty Carton Sealing
Drives the folding arms of heavy-duty corrugated carton sealers, where the short 50 mm stroke delivers rapid 30-800 mm/s actuation and the -S magnet confirms flap position.
Hydraulic Press Brake Gauging
Positions the back-gauge stop on a hydraulic press brake, leveraging the hard-chrome 25 mm rod and ISO 15552 dimensional interchangeability for straightforward retrofitting.
Is the Airtac SE80 Standard Cylinder SE80X50SFA the Right Cylinder?
Selecting this 80 mm bore makes sense when a 63 mm cylinder (providing 1559 N push at 0.5 MPa) lacks the necessary thrust, but stepping up to a 100 mm bore (offering 3927 N push) would be physically oversized. The FA front flange accessory ensures secure axial load mounting, while the PT3/8 port matches standard 80 mm pneumatic flow requirements. If your mechanism must hold a vertical load without continuous air pressure, note that a standard SE cylinder will drift; you should instead specify a BSE series rod-lock variant.
Because the stroke is a short 50 mm, side-loading on the rod bearing is minimal compared to longer strokes. The field-adjustable air cushion at both ends allows you to fine-tune end-of-stroke deceleration via a set screw, preventing harsh impacts during rapid 30-800 mm/s cycling.
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 SE80X50SFA FAQ
At 0.5 MPa, the 80 mm bore provides 2513 N of push force and 2268 N of pull force. At 0.7 MPa, the push force increases to 3518 N, with a maximum push capacity of 513 kgf at 1.0 MPa. The operational speed range is 30-800 mm/s.
Yes, the SE80X50SFA is dimensionally interchangeable per ISO 15552 standards. You can drop it in as a replacement for other 80 mm ISO 15552 profile cylinders using the same FA front flange mounting hardware and PT3/8 port connections.
