About the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC200X50FA
The SC200X50FA is a double-acting pneumatic cylinder with a 200 mm bore and a short 50 mm stroke, equipped with a front rectangular flange (FA) for secure panel or bulkhead mounting. It generates 15708 N of push force at 0.5 MPa and reaches 28274 N at the maximum operating pressure of 0.9 MPa, making it suitable for heavy clamping and pressing tasks.
This tie-rod cylinder uses a 40 mm diameter piston rod with M36x2 threads and PT3/4 ports. The body length A is 244 mm, resulting in a compact extended length of approximately 294 mm. The adjustable air cushion (33 mm) decelerates the piston smoothly at end of stroke, protecting the end cap from impact.

Where the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC200X50FA Is Used
Heavy-Duty Press Frames
Short-stroke 200 mm bore cylinder with front flange mount for integration into hydraulic-style press frames, delivering up to 2.8 tonnes of force for forming or assembly.
Industrial Clamping Systems
Provides rapid, repeatable clamping force for large workpieces on CNC machining centres or welding fixtures, with the FA flange enabling direct mounting to the machine table.
Bulkhead-Mounted Ejectors
Front flange design allows the cylinder body to be mounted behind a bulkhead, with the 40 mm rod extending through to eject heavy parts or scrap from large dies.
Is the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC200X50FA the Right Cylinder?
For applications needing even higher force, the SC250 series provides 24544 N at 0.5 MPa. If a smaller footprint is required, the SC160 bore delivers 10053 N at the same pressure. When replacing an existing cylinder, match five key points: 200 mm bore, 50 mm stroke, PT3/4 port thread, FA front flange mounting (accessory F-SC200FA), and the absence of a magnet sensor option.
Although this is a short-stroke model, the large 40 mm rod is robust; however, any side load should still be managed with an external guide to protect the rod bearing and seals.
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 SC200-250 Tie-Rod Cylinder Aluminum Alloy SC200X50FA FAQ
At 0.5 MPa (approx. 73 psi) the cylinder produces 15708 N of push force. At 0.7 MPa it rises to 21991 N, and at the maximum operating pressure of 0.9 MPa it reaches 28274 N. The theoretical maximum at 1.0 MPa is 3204 kgf.
Yes. The FA suffix designates a front rectangular flange (accessory F-SC200FA) that bolts directly to the rod-end side of a panel or machine frame, supporting the cylinder in a rigid, fixed position.
