About the Airtac SC50 Standard Cylinder SC50X50FB
The AirTAC SC50X50FB is a double-acting tie-rod cylinder with a 50 mm bore and a compact 50 mm stroke, delivering 982 N of push force at 0.5 MPa (1767 N at 0.9 MPa). Its 20 mm diameter piston rod and PT1/4 ports suit short-throw clamping, pressing, and ejector tasks where space is tight but force must be consistent.
This model is configured with an FB rear rectangular flange (accessory F-SC50FB) for rigid end-face mounting. The 21 mm adjustable air cushion at each end decelerates the piston smoothly, reducing end-of-stroke shock. The standard TPU seals provide reliable operation from -20 to +70 °C with filtered air.

Where the Airtac SC50 Standard Cylinder SC50X50FB Is Used
Short-Stroke Clamping
The 50 mm stroke and rear flange mount make this cylinder ideal for machine-tool clamping fixtures where the actuator must be rigidly bolted to a stationary bulkhead.
Compact Pressing
Delivers up to 1767 N at 0.9 MPa in a short body length of just 200 mm overall, fitting neatly into benchtop assembly presses and riveting stations.
Part Ejection
Fast 30-800 mm/s speed range and rear-flange mounting allow reliable pusher or ejector duty on packaging and sorting conveyors.
Is the Airtac SC50 Standard Cylinder SC50X50FB the Right Cylinder?
Choose the SC50X50FB when you need a short-stroke actuator with a rear flange mount for fixed, in-line installation. If your load requires more force, stepping up to the 63 mm bore (SC63 series) provides 1559 N at 0.5 MPa. For lighter, faster cycling, the 40 mm bore (SC40) offers 628 N at 0.5 MPa.
For direct replacement, match five points: 50 mm bore, 50 mm stroke, PT1/4 port thread, FB rear flange mounting, and the standard non-magnetic piston. This tie-rod cylinder is shorter than an ISO 15552 profile and is not dimensionally interchangeable with that standard.
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 SC50X50FB FAQ
At 0.5 MPa the cylinder pushes with 982 N and pulls with 825 N. At the maximum operating pressure of 0.9 MPa, push force reaches 1767 N. The theoretical maximum at 1.0 MPa is 200 kgf.
No. The SC series is a tie-rod cylinder with a shorter overall body length than an ISO 15552 profile cylinder. It is not dimensionally interchangeable. For replacement, match the bore, stroke, port thread, and FB rear flange mount of another AirTAC SC cylinder.
