About the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC200X250H
The SC200X250H is a double-acting pneumatic cylinder with a 200 mm bore and 250 mm stroke, built in AirTAC's tie-rod SC series. At 0.5 MPa it generates 15708 N pushing force and 15080 N pulling force, rising to 28274 N at the maximum 0.9 MPa operating pressure. The 40 mm diameter piston rod and 33 mm adjustable air cushion suit heavy linear actuation tasks where controlled deceleration is required.
This variant carries the 'H' suffix, specifying Viton (FKM) piston and rod seals. The operating temperature range is therefore 0 to +150 °C, making it suitable for hot environments such as foundries, autoclaves, or engine test cells. Ports are standard PT1/2 threads, and the cylinder body length A is 244 mm, giving a total extended length of approximately 494 mm.

Where the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC200X250H Is Used
Heavy Press & Clamping
Delivers up to 28274 N of force at 0.9 MPa for large-scale pressing, die-casting ejection, or industrial clamping fixtures operating in high-temperature zones up to 150°C.
Hot Environment Actuation
Viton seals allow this cylinder to operate continuously in ambient temperatures up to 150°C, making it ideal for autoclave door actuation, kiln mechanisms, and engine test stand automation.
Large Valve & Damper Control
Provides the high thrust and 250 mm stroke needed to open and close heavy industrial butterfly valves, diverter gates, or flue dampers in processing plants.
Is the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC200X250H the Right Cylinder?
Select the SC200 bore when your application needs between roughly 3927 N (SC100 push force at 0.5 MPa) and 15708 N. If your load is below 10053 N at 0.5 MPa, stepping down to the SC160 bore can reduce air consumption and physical size. For strokes of 300 mm or more, always check side-load conditions—the 40 mm rod may require an external guide or a guided cylinder to prevent bearing damage and rod bending under lateral forces.
To replace an existing unit, match five points: 200 mm bore, 250 mm stroke, PT1/2 port thread, basic mounting (no bracket), and no magnet. This model uses Viton seals; a standard TPU-sealed SC200X250 is not a direct substitute in high-temperature circuits.
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 SC200X250H FAQ
At 0.7 MPa supply pressure, the SC200 bore generates a theoretical pushing force of 21991 N. The pulling force on the return stroke is 15080 N at 0.5 MPa; for the exact pull force at 0.7 MPa, confirm from the datasheet as it is not listed in the standard thrust table.
No. The AirTAC SC series is a tie-rod cylinder and is physically shorter than an ISO 15552 profile cylinder of the same bore and stroke. It is not dimensionally interchangeable. It can only directly replace another AirTAC SC tie-rod cylinder with matching 200 mm bore, 250 mm stroke, PT1/2 ports, and basic mounting.
