About the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC200X250STC
The SC200X250STC is a large-bore double-acting pneumatic cylinder delivering 15708 N of push force at 0.5 MPa (28274 N at 0.9 MPa). Its 250 mm stroke is well within the 1500 mm maximum standard stroke for the 200 mm bore, making this a standard-configuration actuator for heavy linear work.
This model includes a built-in magnet (-S) for direct mounting of CMSG/DMSG/EMSG sensors, and ships with a centre trunnion (TC) mount including the TCM1 bracket for pivoting applications. The 40 mm diameter piston rod and 33 mm air cushion provide robust end-of-stroke deceleration for high-inertia loads.

Where the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC200X250STC Is Used
Heavy Press & Clamping
Generates over 28 kN of force at 0.9 MPa, ideal for hydraulic-to-pneumatic press conversions, heavy-duty clamping fixtures, and die-casting extractors where high force in a compact tie-rod package is required.
Pivoting Conveyor Gates
The centre trunnion mount allows the cylinder to pivot freely, making it perfect for actuating heavy diverter gates or tilt tables on aggregate and mining conveyors handling large material volumes.
Large-Format Material Handling
Provides the push capacity for lifting or transferring heavy steel plates, timber packs, or palletized loads in sawmills and steel service centres, with sensor feedback confirming end-of-stroke position.
Is the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC200X250STC the Right Cylinder?
For applications needing more force, the 250 mm bore SC series offers 24544 N at 0.5 MPa. If a lower force and smaller footprint are acceptable, the 160 mm bore provides 10053 N. At a 250 mm stroke, side-loading is a critical consideration with the 40 mm rod—always guide the load externally or use a guided cylinder if off-axis forces are present.
To replace an existing cylinder, match five points: 200 mm bore, 250 mm stroke, PT port thread, centre trunnion (TC) mounting with the F-SC200TC bracket, and the built-in magnet (-S) for sensor compatibility. This tie-rod cylinder is shorter than an ISO 15552 profile and is not dimensionally interchangeable with that standard.
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 SC200X250STC 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 at 1.0 MPa is 3204 kgf.
No. The SC200X250STC is a double-acting cylinder and will drift or drop if pressure is lost or the directional valve is centred. For load holding without live pressure, you must add a pilot-operated check valve or an external mechanical rod lock.
