About the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC250X200STC
The SC250X200STC is a heavy-duty double-acting pneumatic cylinder delivering 24544 N of push force at 0.5 MPa, rising to 44178 N at the maximum operating pressure of 0.9 MPa. With a 250 mm bore and 200 mm stroke, it features a 50 mm diameter piston rod, PT1" ports, and a 40 mm adjustable air cushion to decelerate large inertial loads smoothly.
This model is configured with a built-in magnet (-S) for direct mounting of CMSG/DMSG/EMSG sensors, and a centre trunnion (TC) mount that ships with the TCM1 bracket, allowing the cylinder to pivot for swinging load applications. It uses standard TPU seals for a temperature range of -20 to +70 °C and PT threaded ports.

Where the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC250X200STC Is Used
Heavy Press & Clamping
Generates up to 44178 N of force at 0.9 MPa for stamping, pressing, and heavy-duty clamping fixtures in metal fabrication.
Pivoting Conveyor Gates
The centre trunnion mount allows the cylinder to pivot, ideal for actuating heavy diverter gates or chutes on aggregate and mining conveyors.
Large Part Ejection
Provides the high force needed to eject large, heavy parts from molds or fixtures, with a 40 mm cushion to absorb impact energy.
Is the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC250X200STC the Right Cylinder?
Select the SC250 for applications requiring forces up to 24544 N at 0.5 MPa. If your force requirement is lower, stepping down to the SC200 bore provides 15708 N of push force at the same pressure. For side-loaded or long-stroke applications, always use an external guide or a guided cylinder to protect the 50 mm rod from bending moments.
To ensure a correct drop-in replacement, match these five points: 250 mm bore, 200 mm stroke, PT1" port thread, centre trunnion (TC) mounting with TCM1 bracket, and the built-in magnet (-S) for sensor compatibility.
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 SC250X200STC FAQ
At 0.5 MPa, the push force is 24544 N and the pull force is 23562 N. At the maximum operating pressure of 0.9 MPa, the push force reaches 44178 N. The theoretical maximum force at 1.0 MPa is 5006 kgf.
No. The SC250 is a standard double-acting cylinder and will not hold its position if air pressure is lost or the directional valve is centered. For load holding, you must add an external rod brake, a mechanical lock, or a pilot-operated check valve.
