About the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC250X1000TC
The AirTAC SC250X1000TC is a large-bore double-acting tie-rod cylinder delivering a substantial 24544 N of push force at 0.5 MPa (44178 N at the maximum 0.9 MPa operating pressure). With a 50 mm diameter piston rod and a 1000 mm stroke, this ISO 6430 class actuator is built for heavy industrial linear motion tasks.
This model features a centre trunnion (TC) mount, supplied with the TCM1 bracket (F-SC250TC), allowing the cylinder to pivot and accommodate swinging loads. The adjustable air cushion (40 mm length) decelerates the piston smoothly at stroke ends, protecting the end caps during high-energy stops. The body length A is 294 mm, and the port size is PT1".

Where the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC250X1000TC Is Used
Heavy Press Tool Actuation
Operates large forming or stamping press tools requiring over 20 kN of consistent push force through a 1-meter stroke, with trunnion mounting to allow the cylinder to follow the tool arc.
Bulk Material Gate Control
Drives heavy slide gates or diverter chutes in mining and aggregate handling, using the 24544 N force at 0.5 MPa to move dense material columns reliably.
Steel Mill Tilter Mechanism
Pivots a heavy coil tilter or transfer table in a steel processing line. The TC mount supports the swinging motion, and the 40 mm cushion absorbs the high inertial energy of the 1-meter stroke.
Is the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC250X1000TC the Right Cylinder?
Select the SC250 when your application requires a force class above 20000 N at standard plant air pressure. For a step down in force, the SC200 bore provides 15708 N push at 0.5 MPa. For a step up, this is the largest standard SC bore. At a 1000 mm stroke, ensure the rod is guided externally if significant side loads are present, as the unsupported length can induce bending stress on the 50 mm rod and bearings.
To replace an existing cylinder, match five points exactly: 250 mm bore, 1000 mm stroke, PT1" port thread, centre trunnion (TC) mounting with the TCM1 bracket, and confirm the magnet requirement (this model has no built-in magnet).
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 SC250X1000TC FAQ
At 0.5 MPa, 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 reaches 44178 N. The theoretical maximum force at 1.0 MPa is 5006 kgf.
No. The SC250 is a double-acting cylinder and will drift or drop if pressure is lost or the directional valve is centered. For load holding without live pressure, you must add an external rod brake, a mechanical lock, or a pilot-operated check valve in the circuit.
