About the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC250X850CA
The SC250X850CA is a large-bore double-acting pneumatic cylinder delivering 24544 N of push force at 0.5 MPa and up to 44178 N at the maximum operating pressure of 0.9 MPa. With an 850 mm stroke and a 50 mm diameter piston rod, this model is built for heavy industrial linear motion tasks requiring substantial thrust.
This configuration includes a rear single clevis (CA) mounting, part F-SC250CA, allowing the cylinder to pivot during operation. The body length A is 294 mm, and the adjustable air cushion at each end is 40 mm, providing effective end-of-stroke deceleration for the high inertial loads typical at this bore size.

Where the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC250X850CA Is Used
Heavy-Duty Material Handling
Provides the high push force needed to lift, tilt, or transfer heavy pallets and bulk materials in demanding industrial environments.
Large-Scale Clamping & Pressing
Delivers up to 44178 N of force for secure clamping of large weldments or workpieces in heavy machining and fabrication fixtures.
Industrial Damper & Gate Actuation
Operates large dampers, chute gates, and diverter valves in processing plants, with a rear clevis mount for pivoting installation.
Is the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC250X850CA the Right Cylinder?
Select the SC250 when your application demands forces in the 24544 N (push) and 23562 N (pull) range at 0.5 MPa. For a step down in force, the SC200 bore provides 15708 N push at the same pressure. For a step up, this is the largest standard SC bore. The 850 mm stroke is within the 1500 mm maximum standard stroke for this bore.
For strokes of this length, ensure the 50 mm rod is adequately supported against side loads; an external guide or a guided cylinder is recommended to prevent rod bending and premature bearing wear. When replacing, match the 250 mm bore, 850 mm stroke, PT port thread, CA rear clevis mount, and confirm the magnet/sensor requirement.
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 SC250X850CA FAQ
At the standard 0.5 MPa operating pressure, the push force is 24544 N and the pull force is 23562 N. At the maximum operating pressure of 0.9 MPa, the push force increases to 44178 N.
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, so it is not dimensionally interchangeable. It is a direct replacement only for another AirTAC SC250 tie-rod cylinder with matching bore, stroke, PT port, and CA rear clevis mount.
