About the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC200X400CA
The SC200X400CA is a large-bore double-acting pneumatic cylinder delivering a substantial 15708 N of push force at 0.5 MPa (28274 N at 0.9 MPa). With a 400 mm stroke and a 40 mm diameter piston rod, it is built for heavy linear actuation tasks where high force and a pivoting mount are required.
This model features a rear single clevis (CA) mount, part F-SC200CA, allowing the cylinder to pivot during operation to accommodate angular misalignment. The body length A is 244 mm, and the total extended length is approximately 644 mm. It uses a PT1/2 port and an M36x2 rod thread, with an adjustable air cushion of 33 mm to decelerate the piston smoothly.

Where the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC200X400CA Is Used
Heavy Agricultural Machinery
Provides the high force needed for lifting and tilting mechanisms on harvesters, sprayers, and tillage equipment, with the CA clevis mount allowing free pivoting on uneven terrain.
Industrial Press Feed
Delivers 28274 N of thrust at 0.9 MPa to reliably push heavy steel sheet or plate stock into stamping presses, with the adjustable cushion protecting the tooling from impact damage.
Wastewater Gate Valve Actuation
Operates large sluice or gate valves in water treatment plants, where the high force overcomes sludge buildup and the pivoting clevis mount handles the valve's arc of motion.
Is the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC200X400CA the Right Cylinder?
Select the SC200 bore when your application requires a push force between roughly 3927 N (SC100 at 0.5 MPa) and 15708 N. For a 400 mm stroke, ensure the rod is adequately supported against side loads; an external guide or guided cylinder is recommended to prevent rod bending and premature bearing wear. If your force requirement is lower, stepping down to a 160 mm bore (10053 N at 0.5 MPa) can reduce air consumption and physical size.
For a direct replacement, match these five points: 200 mm bore, 400 mm stroke, PT port thread, CA rear single clevis mounting, and the standard TPU seal. This is a tie-rod cylinder and is not dimensionally interchangeable with ISO 15552 profile cylinders.
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 SC200X400CA FAQ
At the standard 0.5 MPa operating pressure, the push force is 15708 N. At 0.7 MPa it is 21991 N, and at the maximum 0.9 MPa operating pressure, the force reaches 28274 N. The theoretical maximum at 1.0 MPa is 3204 kgf.
No. The SC200X400CA is a double-acting cylinder and will not hold its position if air pressure is lost or the directional valve is centered. For load-holding applications, you must add an external rod lock, a mechanical brake, or a pilot-operated check valve.
