About the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC200X500SH
The SC200X500SH is a large-bore double-acting tie-rod cylinder delivering substantial force for heavy industrial automation. At 0.5 MPa it pushes with 15708 N and pulls with 15080 N, rising to a commanding 28274 N push at the maximum operating pressure of 0.9 MPa. The 500 mm stroke is well within the 1500 mm maximum standard range for this 200 mm bore, and the piston is cushioned over a 33 mm travel at each end to manage high inertial loads smoothly.
This model is factory-configured with a built-in magnet (-S suffix) so CMSG, DMSG, or EMSG sensors can clamp directly onto the tie-rod barrel for non-contact position sensing. The -H suffix specifies Viton (FKM) seals, shifting the operating temperature envelope from the standard -20 to +70 °C up to 0 to +150 °C, making this cylinder suitable for hot environments such as foundries, autoclaves, or engine test cells. The 40 mm diameter piston rod features an M36x2 knuckle thread, and the standard PT3/4 port supplies the large air volume this bore demands.

Where the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC200X500SH Is Used
High-Temperature Press Actuation
With Viton seals rated to 150 °C, this cylinder is ideal for operating platen presses, autoclave doors, or thermoforming clamps where ambient heat would degrade standard seals. The 28274 N push force at 0.9 MPa provides the clamping tonnage these processes demand.
Heavy-Duty Material Handling
The 15708 N push at 0.5 MPa moves heavy steel coils, large castings, or palletized loads on transfer lines. The built-in magnet allows CMSG/DMSG sensors to verify full extension and retraction, integrating seamlessly with safety interlocks and automated sequences.
Foundry & Forge Auxiliary Motion
Rated for continuous operation in high-ambient-temperature environments, this cylinder powers sand rammers, shakeout gates, and manipulator arms. The 33 mm air cushion at each end decelerates the high-inertia load smoothly, reducing shock and noise on the machine structure.
Is the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC200X500SH the Right Cylinder?
Choose the SC200X500SH when your application needs roughly 15-28 kN of push force and must withstand ambient temperatures up to 150 °C. If your force requirement is lower, stepping down to a 160 mm bore reduces push force to 10053 N at 0.5 MPa; if you need even greater force, the 250 mm bore delivers 24544 N at the same pressure. Always match replacement cylinders on five points: 200 mm bore, 500 mm stroke, PT port thread, the built-in magnet for sensors, and the Viton seal material for high-temperature compatibility.
At a 500 mm stroke, the 40 mm rod is robust, but any significant side load can still cause rod bearing wear or bending. For applications where the load is not guided externally, consider pairing this cylinder with an external linear guide or switching to a guided actuator to protect the rod and seals and ensure consistent, long-life operation.
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 SC200X500SH FAQ
At 0.7 MPa operating pressure, the SC200X500SH generates 21991 N of push force on the piston face and 15080 N of pull force on the rod side. The theoretical maximum push force at 1.0 MPa is 3204 kgf, though the maximum rated operating pressure is 0.9 MPa, which yields 28274 N.
No. The SC200X500SH is a standard double-acting cylinder and will drift or drop if air pressure is lost, exhausted, or the directional valve is centered. Its adjustable air cushion only decelerates the piston at end-of-stroke—it is not a lock or brake. For load holding without live pressure, you must add an external rod lock, a pilot-operated check valve, or a mechanical brake.
