About the Airtac SC50 Standard Cylinder SC50X100FB
The SC50X100FB is a 50 mm bore, 100 mm stroke double-acting pneumatic cylinder delivering 982 N of push force at 0.5 MPa (1767 N at 0.9 MPa). Its 20 mm diameter piston rod and 21 mm adjustable air cushion provide reliable deceleration for mid-range linear tasks.
This model is configured with a rear rectangular flange (FB) for secure end-face mounting, using the standard PT1/4 port thread and TPU seals rated for -20 to +70 °C. The tie-rod construction keeps the body length A compact at 150 mm, making it a practical choice where space behind the mounting face is limited.

Where the Airtac SC50 Standard Cylinder SC50X100FB Is Used
Clamping & Fixturing
The 982 N push force at 0.5 MPa makes this cylinder ideal for pneumatic clamping, holding workpieces during machining or assembly, where the FB flange provides a rigid, stationary anchor point.
Part Stops & Diverters
Use the 100 mm stroke to extend a stop pin or diverter gate on a conveyor line. The adjustable cushion softens the impact at full extension, protecting the product and reducing noise.
Press & Forming Assist
Deploy the SC50X100FB in light press or forming operations. The rear flange mount handles the reaction force directly into the press frame, while the 20 mm rod withstands repetitive push cycles.
Is the Airtac SC50 Standard Cylinder SC50X100FB the Right Cylinder?
Select the SC50 for applications needing around 982 N at 0.5 MPa. If your force requirement drops below 600 N, stepping down to the 40 mm bore (628 N) can reduce air consumption; for cyclic loads above 1400 N, moving to the 63 mm bore (1559 N) provides a safer margin. The FB rear flange rigidly fixes the cylinder cap to a machine frame or panel.
When replacing an existing cylinder, match five points to ensure drop-in compatibility: 50 mm bore, 100 mm stroke, PT1/4 port thread, FB rear flange mounting (part F-SC50FB), and confirm the absence of a magnetic piston. For strokes of 300 mm or longer, always evaluate side-load forces on the 20 mm rod and consider an external guide to prevent bearing wear.
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 SC50X100FB FAQ
At the standard 0.5 MPa operating pressure, the cylinder pushes with 982 N and pulls with 825 N. At the maximum operating pressure of 0.9 MPa, the push force increases to 1767 N. The theoretical maximum at 1.0 MPa is 200 kgf.
No. The AirTAC SC series is a tie-rod cylinder that is physically shorter than an ISO 15552 profile cylinder, so mounting dimensions and body length A (150 mm) will differ. It is a direct replacement only for another AirTAC SC50 tie-rod cylinder matching the 100 mm stroke, PT1/4 port, and FB rear flange mount.
