About the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC200X200H
The AirTAC SC200X200H is a large-bore double-acting pneumatic cylinder engineered for high-force applications in elevated-temperature environments. With a 200 mm bore and 200 mm stroke, it generates a substantial push force of 15708 N at 0.5 MPa and up to 28274 N at 0.9 MPa, driven by a robust 40 mm diameter piston rod.
This model is equipped with Viton (FKM) seals, designated by the 'H' suffix, which shifts the operating temperature range from the standard -20 to +70 °C up to 0 to +150 °C. The cylinder features a 33 mm adjustable air cushion, PT3/4 port threads, and a body length of 244 mm, making it a durable choice for hot or aggressive industrial atmospheres.

Where the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC200X200H Is Used
High-Temperature Clamping
The Viton seals enable this cylinder to operate reliably in ovens, autoclaves, or near heat sources up to 150°C, providing consistent clamping force for hot material processing.
Heavy-Duty Pressing
Delivering up to 28274 N of force at 0.9 MPa, the SC200X200H is ideal for hydraulic-free pressing, stamping, and forming operations where a compact pneumatic power source is preferred.
Large Valve Actuation
Use this 200 mm bore cylinder to automate large industrial valves or dampers in chemical and power generation plants, especially where process heat requires FKM seal compatibility.
Is the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC200X200H the Right Cylinder?
Select the SC200X200H when your application demands a force output between 15 and 28 kN. If your load requires less force, stepping down to the SC160 bore reduces the push force to 10053 N at 0.5 MPa, potentially saving space and air consumption. For strokes exceeding 300 mm on this 40 mm rod, evaluate side-load forces carefully; an external guide or guided cylinder is recommended to prevent rod bearing damage and ensure linear motion integrity.
As a direct replacement, this cylinder matches the AirTAC SC200 series tie-rod dimensions. When replacing, verify five key points: 200 mm bore, 200 mm stroke, PT3/4 port thread, the high-temperature Viton seal specification, and the basic (no magnet) configuration.
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 SC200X200H FAQ
The theoretical push force at 0.5 MPa is 15708 N, and the pull force is 15080 N. At the maximum operating pressure of 0.9 MPa, the push force reaches 28274 N. The absolute maximum theoretical force at 1.0 MPa is 3204 kgf, but operation is limited to 1.0 MPa.
No. The SC200X200H is a double-acting cylinder and will not hold its position if air pressure is lost or the directional valve is centered. The piston will drift or the load will drop. For load-holding safety, you must add an external rod brake, a mechanical lock, or a pilot-operated check valve.
