About the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC250X160H
The AirTAC SC250X160H is a heavy-duty double-acting tie-rod cylinder with a 250 mm bore and 160 mm stroke, factory-equipped with high-temperature Viton (FKM) seals for reliable operation from 0 to +150 °C. It delivers a substantial push force of 24544 N at 0.5 MPa and reaches 44178 N at the maximum operating pressure of 0.9 MPa, placing it in the highest force class of the standard SC single-rod range.
This model features a 50 mm diameter piston rod with an M42x2 knuckle thread and a 40 mm adjustable air cushion at each end to decelerate large inertial loads smoothly. The body length A is 294 mm, giving a total extended length of approximately 454 mm. The PT1 inch port supplies the large air volume required, and the cylinder conforms to the ISO 6430 class for heavy-duty tie-rod construction.

Where the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC250X160H Is Used
High-Temperature Press & Forming
The Viton seals allow the SC250X160H to operate continuously in hot press, autoclave, or thermoforming tooling at up to 150°C, delivering 44 kN of clamping force.
Heavy Foundry & Mill Actuation
With 24544 N of push force at standard shop air, this cylinder powers large gates, dampers, and material diverters in steel mills and foundries where ambient heat is present.
Waste Compaction & Baling
The 250 mm bore provides the extreme thrust needed for compacting recyclables or waste material, while the 40 mm cushion absorbs the shock of high-speed compaction rams.
Is the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC250X160H the Right Cylinder?
Select the SC250 when your application requires a push force between roughly 24500 N (at 0.5 MPa) and 44178 N (at 0.9 MPa). If your force requirement is lower, stepping down to the SC200 bore reduces push force to 15708 N at 0.5 MPa, saving space and air consumption. For strokes of 300 mm or longer, always evaluate side-load and rod-bearing bending moments; an external guide or a guided cylinder is recommended to protect the 50 mm rod from deflection under non-axial loads. When replacing this unit, match five points: 250 mm bore, 160 mm stroke, PT port thread, basic mount (no integrated bracket), and the H-suffix Viton seal for high-temperature compatibility.

- ✓ 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 SC250X160H FAQ
At 0.7 MPa (7 bar) supply pressure, the theoretical push force is 34361 N. The pull force on the retract stroke is 23562 N at 0.5 MPa, reduced by the 50 mm rod area.
No. The SC250X160H is a double-acting cylinder and will drift or drop if air pressure is lost or the directional valve is centered. For load holding, you must add an external rod brake, a mechanical lock, or a pilot-operated check valve.
