About the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC200X400SH
The SC200X400SH is a large-bore double-acting pneumatic cylinder delivering substantial force for heavy-duty industrial automation. At 0.5 MPa it generates 15708 N pushing and 15080 N pulling, rising to a powerful 28274 N push force at the maximum operating pressure of 0.9 MPa.
This model features a 40 mm diameter piston rod with M36x2 male threads and a 33 mm adjustable air cushion at each end to decelerate high-inertia loads smoothly. The -S suffix denotes a built-in magnet for mounting CMSG/DMSG/EMSG sensors directly on the tie-rod barrel, while the -H suffix upgrades the seals to Viton (FKM), extending the operating temperature range to 0–150 °C for hot-environment duty.

Where the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC200X400SH Is Used
Heavy Press & Clamping
Generates up to 28274 N at 0.9 MPa for stamping, riveting, and high-force clamping fixtures in automotive and metal fabrication lines.
Palletising & Lifting
The 15080 N pull force at 0.5 MPa reliably raises and lowers heavy pallets or lift tables in packaging and logistics centres.
High-Temperature Actuation
Viton seals permit continuous operation in ambient temperatures up to 150 °C, ideal for foundry equipment, autoclaves, and engine test cells.
Is the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC200X400SH the Right Cylinder?
Select the SC200 when your application requires approximately 15708 N of force at standard 0.5 MPa shop air. If your load is lighter, stepping down to an SC160 bore reduces push force to 10053 N at the same pressure; for even higher force, the SC250 bore provides 24544 N at 0.5 MPa. Always match the replacement cylinder on all five key points: 200 mm bore, 400 mm stroke, PT port thread, the -S magnet option for sensor compatibility, and the -H Viton seal material.
With a 400 mm stroke, the 40 mm rod is robust, but any significant side loading can still cause rod bearing wear or bending. For guided or cantilevered loads, pair this cylinder with an external linear guide or consider a guided-cylinder configuration to protect the rod and seals over millions of cycles.
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 SC200X400SH FAQ
At 0.5 MPa, the cylinder produces 15708 N pushing and 15080 N pulling. At the maximum operating pressure of 0.9 MPa, push force reaches 28274 N. The theoretical maximum at 1.0 MPa is 3204 kgf.
No. The SC200 is a standard double-acting cylinder and will drift or drop if pressure is exhausted or the directional valve is centred. For load-holding without live pressure, you must add a pilot-operated check valve, external rod lock, or mechanical brake.
