About the Airtac SC50 Standard Cylinder SC50X50FA
The SC50X50FA is a double-acting pneumatic cylinder from the AirTAC SC tie-rod series, configured with a 50 mm bore and a compact 50 mm stroke. It generates a push force of 982 N at 0.5 MPa and up to 1767 N at the maximum operating pressure of 0.9 MPa, driven by a 20 mm diameter piston rod with M16x1.5 male threads.
This model includes a front rectangular flange (mounting type FA, accessory code F-SC50FA) for rigid panel or bulkhead mounting. The standard PT1/4 port, TPU seals with a -20 to +70 °C range, and 21 mm adjustable air cushion ensure reliable deceleration in short-stroke clamping and pressing tasks.

Where the Airtac SC50 Standard Cylinder SC50X50FA Is Used
Part Stops & Gates
The 50 mm stroke and 982 N push force at 0.5 MPa make this cylinder ideal for actuating part stops or small gates on conveyor lines, providing a firm, repeatable hold.
Light Clamping Fixtures
Directly flange-mount this cylinder to a fixture plate for consistent clamping in machining or assembly. The front flange ensures rigid alignment for the 20 mm rod.
Ejection Mechanisms
Use the SC50X50FA as a compact ejector for small parts. The adjustable cushion softens the end-of-stroke impact, protecting tooling at high cycle rates.
Is the Airtac SC50 Standard Cylinder SC50X50FA the Right Cylinder?
Choose the SC50X50FA when your application needs a 50 mm bore for push forces around 982 N at standard plant pressure. If you require higher force, step up to the SC63 bore (1559 N push at 0.5 MPa); for a lighter, more compact solution, the SC40 bore provides 628 N. The 50 mm stroke is well within standard limits, but always align the rod axis with the load to prevent side-load binding.
To replace an existing cylinder, match five key points: 50 mm bore, 50 mm stroke, PT1/4 port thread, front flange (FA) mounting, and the absence of a magnet. This is a tie-rod cylinder and is not dimensionally interchangeable with ISO 15552 profiles.
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 SC50 Standard Cylinder SC50X50FA FAQ
At 0.5 MPa, the push force is 982 N. At 0.7 MPa it rises to 1374 N, and at the maximum operating pressure of 0.9 MPa it reaches 1767 N. The theoretical maximum at 1.0 MPa is 200 kgf.
No. The AirTAC SC series is a tie-rod cylinder and is physically shorter than an ISO 15552 cylinder of the same bore and stroke. It is a direct replacement only for another AirTAC SC50 tie-rod cylinder with matching stroke, port, and FA front flange mount.
