About the Airtac SC80 Standard Cylinder SC80X50SFB
The SC80X50SFB is an 80 mm bore double-acting pneumatic cylinder from the AirTAC SC tie-rod series, delivering a push force of 2513 N at 0.5 MPa. With a compact 50 mm stroke and a 25 mm diameter piston rod, this model is built for short-throw clamping, pressing, and ejecting tasks where space is limited.
This specific configuration includes a built-in magnet (-S) for mounting CMSG/DMSG/EMSG sensors directly on the barrel, and an FB rear rectangular flange (F-SC80FB) for rigid end-face mounting. The adjustable air cushion (28 mm length) decelerates the piston smoothly, and the PT1/4 port thread ensures straightforward pneumatic connections.

Where the Airtac SC80 Standard Cylinder SC80X50SFB Is Used
Part Stops & Gates
The 2513 N push force at 0.5 MPa and 50 mm stroke make this cylinder ideal for actuating heavy-duty part stops or sorting gates on conveyor lines, with the magnet providing end-of-stroke confirmation.
Fixture Clamping
Rigid rear-flange mounting and a short stroke suit this cylinder for securely clamping workpieces in CNC machining fixtures or welding jigs, resisting deflection under high thrust.
Short-Stroke Pressing
With a maximum theoretical force of 513 kgf at 1.0 MPa, this unit can be used in small assembly presses for bearing insertion, riveting, or staking operations requiring a compact footprint.
Is the Airtac SC80 Standard Cylinder SC80X50SFB the Right Cylinder?
For applications needing more force, consider stepping up to the SC100 bore, which provides 3927 N of push force at the same 0.5 MPa pressure. If a shorter overall length is required, the SC63 bore offers 1559 N but with a smaller 20 mm rod.
To ensure a drop-in replacement, match all five key points: 80 mm bore, 50 mm stroke, PT port thread, rear flange (FB) mounting, and the integrated magnet (-S). This SC cylinder is a tie-rod design and is not dimensionally interchangeable with ISO 15552 profile cylinders.
Quick checklist
- ✓ Required force at your working pressure
- ✓ Stroke and mounting space
- ✓ Port/thread type (PT/NPT/G)
- ✓ Magnet (-S) for 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 (FA/FB/CA/CB/LB/TC).
- check Installation by qualified personnel per AirTAC docs.
Airtac SC80 Standard Cylinder SC80X50SFB FAQ
At the standard operating pressure of 0.5 MPa, the push force is 2513 N and the pull force is 2268 N. At the maximum operating pressure of 0.9 MPa, the push force increases to 4523 N. The theoretical maximum force at 1.0 MPa is 513 kgf.
No. The AirTAC SC series is a tie-rod cylinder with a shorter overall body length than an ISO 15552 profile cylinder. It is a direct match only for another AirTAC SC tie-rod cylinder with an 80 mm bore, 50 mm stroke, PT ports, rear flange (FB) mounting, and a magnet.
