About the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC200X350SH
The SC200X350SH is a large-bore double-acting tie-rod cylinder delivering 15708 N of push force at 0.5 MPa and up to 28274 N at 0.9 MPa. With a 40 mm piston rod, M36x2 rod thread, and a 33 mm adjustable air cushion, it is built for heavy industrial actuation where high force and high temperature tolerance are required.
This variant includes a built-in magnet (-S) for direct mounting of CMSG/DMSG/EMSG sensors, and Viton (FKM) seals (-H) that shift the operating temperature range to 0 to +150 °C. The 350 mm stroke is well within the 1500 mm maximum standard stroke for this bore, and the body length A is 244 mm.

Where the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC200X350SH Is Used
High-Temperature Foundry Actuation
Viton seals allow operation up to 150°C, making this cylinder suitable for clamping molds, operating furnace doors, or actuating dampers in foundries and heat-treatment facilities.
Heavy-Duty Pressing & Forming
With 28274 N of force at 0.9 MPa, the SC200X350SH excels in hydraulic-press replacements, heavy material forming, and large-part assembly presses where consistent pneumatic power is critical.
Automated Pallet Transfer Systems
The built-in magnet enables end-of-stroke sensing with CMSG/DMSG sensors, providing precise position feedback for pallet lifts, transfer cars, and heavy conveyor diverters in automated lines.
Is the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC200X350SH the Right Cylinder?
For a 200 mm bore, this cylinder generates 15708 N push at 0.5 MPa. If your load requires less force, stepping down to a 160 mm bore (10053 N at 0.5 MPa) may reduce air consumption. For larger loads, a 250 mm bore provides 24544 N at the same pressure. At a 350 mm stroke, the 40 mm rod is robust, but always avoid direct side loading; use an external guide or linear bearing to protect the rod bearing from bending moments.
To replace an existing unit, match five points: 200 mm bore, 350 mm stroke, PT port thread, the built-in magnet for sensor compatibility, and the Viton seal material for high-temperature operation. The SC is a tie-rod cylinder and is not dimensionally interchangeable with ISO 15552 profile cylinders.
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 SC200X350SH FAQ
At 0.5 MPa, the push force 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 theoretical maximum force at 1.0 MPa is 3204 kgf.
No. The SC200X350SH is a standard double-acting cylinder and will drift or drop if air pressure is exhausted or the directional valve is centered. For load holding without live pressure, you must add an external rod brake, a mechanical lock, or a pilot-operated check valve.
