About the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC200X200SH
The SC200X200SH is a large-bore tie-rod cylinder built for high-force industrial automation. At 0.5 MPa operating pressure, this 200 mm bore unit generates 15708 N of push force, scaling up to a powerful 28274 N at the maximum 0.9 MPa working pressure.
This model includes a built-in magnet (-S suffix), allowing direct mounting of CMSG, DMSG, or EMSG sensors on the barrel for reliable, non-contact position sensing. The -H suffix designates Viton (FKM) seals, extending the operating temperature range to 0 to +150 °C, making it suitable for hot environments like foundries or autoclaves. It features a 40 mm diameter piston rod with an M36x2 thread and a 33 mm adjustable air cushion for smooth deceleration of heavy loads.

Where the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC200X200SH Is Used
High-Temperature Press
With Viton seals rated to +150 °C, this cylinder is ideal for hot press platens, autoclave door actuation, and foundry equipment where standard seals would degrade.
Heavy-Duty Material Handling
Generating over 28 kN at 0.9 MPa, the SC200X200SH powers large transfer carts, lift tables, and structural testing rigs requiring immense push force.
Automated Process Valve Actuation
The built-in magnet enables precise end-of-stroke feedback via CMSG sensors, perfect for sequencing large quarter-turn valves or diverters in processing plants.
Is the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC200X200SH the Right Cylinder?
Select the SC200 for applications demanding between 15000 N and 28000 N of force. If your load requires less force, stepping down to a 160 mm bore reduces the push force to 10053 N at 0.5 MPa, potentially saving on air consumption. For any replacement, ensure a perfect 5-point match: 200 mm bore, 200 mm stroke, PT port thread, the built-in magnet for sensor compatibility, and the Viton seal material for high-temperature operation.
For this 200 mm stroke, side-loading is a critical consideration. The 40 mm rod is robust, but any radial force will create a bending moment at the rod bearing. For applications with misalignment or attached tooling weight, use an external guide rail or a guided cylinder to absorb side loads and prevent premature seal and bearing wear.
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 SC200X200SH FAQ
The theoretical push force at 0.5 MPa is 15708 N, and at the maximum operating pressure of 0.9 MPa it reaches 28274 N. The theoretical maximum force at 1.0 MPa is 3204 kgf.
No. The SC200 is a standard double-acting cylinder and will not hold its position if air pressure is exhausted or the directional valve is centered. For load holding, you must add a pilot-operated check valve or an external mechanical rod lock.
