About the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC200X175STC
The AirTAC SC200X175STC is a double-acting tie-rod cylinder delivering 15708 N push force at 0.5 MPa and up to 28274 N at 0.9 MPa operating pressure. Its 40 mm diameter piston rod and 33 mm adjustable air cushion are sized for heavy industrial loads, while the 175 mm stroke suits medium-travel clamping and pressing tasks.
This model includes a built-in magnet (-S) for direct mounting of CMSG/DMSG/EMSG sensors, plus a centre trunnion mount (TC) supplied with the TCM1 bracket (F-SC200TC). The trunnion allows the cylinder to pivot, accommodating angular motion in the application. Total extended body length is approximately 419 mm (body length A 244 mm + 175 mm stroke).

Where the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC200X175STC Is Used
Heavy Press Tool Actuation
Generates up to 28274 N of push force at 0.9 MPa for stamping, riveting, or die-cushion actuation in metal forming presses.
Pivoting Clamp & Fixture
The centre trunnion mount (TC) allows the cylinder body to swing, ideal for large weld fixtures or assembly jigs that need to retract clear of the workpiece.
Bulk Material Gate Control
Operates heavy slide gates or diverter chutes in silos and material handling lines, with magnetic piston sensors confirming open/closed position.
Is the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC200X175STC the Right Cylinder?
Choose the SC200 for force requirements above 15708 N at 0.5 MPa; if your load is lighter, step down to the SC160 bore (10053 N at 0.5 MPa) to reduce air consumption and physical size. For strokes of 300 mm or longer, evaluate side-load conditions carefully—a 40 mm rod under high compressive load may require an external guide or guided cylinder to prevent rod-bearing bending.
To ensure a drop-in replacement, match five key points: 200 mm bore, 175 mm stroke, PT port thread, centre trunnion (TC) mounting with TCM1 bracket, and the built-in magnet (-S) for sensor compatibility. This SC model is a tie-rod design 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 SC200X175STC FAQ
At 0.5 MPa air pressure, push force is 15708 N and pull force is 15080 N. At the maximum operating pressure of 0.9 MPa, push force reaches 28274 N. The theoretical maximum at 1.0 MPa is 3204 kgf (31400 N).
No. The SC200 is a standard double-acting cylinder and will drift or drop if air pressure is exhausted or the directional valve is centred. For load holding without live pressure, you must add a pilot-operated check valve, rod lock, or external mechanical brake—the adjustable air cushion only decelerates the piston at stroke end and does not lock the position.
