About the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC200X300H
The SC200X300H is a large-bore, double-acting tie-rod cylinder built for high-temperature duty. Its Viton (FKM) seals shift the operating range to 0–150 °C, making it suitable for autoclaves, foundries, and hot-process automation where standard polyurethane would degrade. At 0.5 MPa air pressure, this 200 mm bore unit generates 15 708 N push force and 15 080 N pull force, rising to 28 274 N of thrust at the maximum 0.9 MPa operating pressure.
With a 40 mm diameter piston rod and M36×2 rod thread, the cylinder handles substantial column loads. The 300 mm stroke is well within the 1500 mm maximum standard stroke for bore 200, keeping lead times short. Adjustable air cushioning at both ends (33 mm cushion length) decelerates the heavy piston smoothly, protecting end caps and reducing noise. The body length A is 244 mm, giving a total extended length of approximately 544 mm. Ports are PT 3/4.

Where the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC200X300H Is Used
Hot-Process Actuation
Viton seals allow continuous operation at 150 °C, making this cylinder ideal for autoclave door clamping, glass-forming press actuation, and steam-process valve control where standard seals would fail.
Heavy Press & Clamp
With 28 274 N of force at 0.9 MPa, the SC200X300H powers large forming presses, injection-mould core pulls, and structural welding fixtures that require high clamping force in a compact tie-rod envelope.
Bulk Material Handling
The 300 mm stroke and high thrust move heavy gates, diverters, and hopper slides in hot, dusty environments such as cement plants, steel mills, and bulk-food processing lines.
Is the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC200X300H the Right Cylinder?
Select the SC200 for applications demanding 15–28 kN of pneumatic force. If your load requires less than 10 kN, stepping down to a 160 mm bore (10 053 N push at 0.5 MPa) saves air consumption and physical space. For strokes of 300 mm and above with a 40 mm rod, evaluate side-loading carefully—any off-axis force can bend the rod or wear the bearing. When the load is not guided externally, add an external guide rail or switch to a guided cylinder to protect the rod and seals.
To replace an existing cylinder, match five points: 200 mm bore, 300 mm stroke, PT 3/4 port thread, basic mount (no bracket), and the absence of a magnet. The SC200X300H uses Viton seals, so confirm the original also ran at elevated temperature; if the original used standard seals, the -H variant is an upgrade for hot environments. This is a tie-rod cylinder—do not attempt to drop it into an ISO 15552 profile footprint.
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 SC200X300H FAQ
At 0.5 MPa (5 bar) the cylinder produces 15 708 N pushing and 15 080 N pulling. At the maximum operating pressure of 0.9 MPa, push force reaches 28 274 N. The theoretical maximum at 1.0 MPa is 3204 kgf. Always apply a safety factor for real-world dynamic loads.
No. The SC series is a tie-rod cylinder and is physically shorter than an ISO 15552 profile cylinder of the same bore and stroke. The mounting dimensions and body length differ. It replaces another AirTAC SC tie-rod cylinder or a compatible tie-rod design with matching bore, stroke, PT 3/4 ports, and basic mount. For hot environments, the -H Viton seal variant is the correct choice.
