About the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC200X80TC
The SC200X80TC is a large-bore double-acting pneumatic cylinder delivering 15708 N of push force at 0.5 MPa (28274 N at the 0.9 MPa maximum operating pressure). With an 80 mm stroke and a 40 mm diameter piston rod, it suits heavy linear actuation where the load is pivoted during motion.
This model includes a centre trunnion (TC) mount, supplied with the TCM1 bracket (F-SC200TC), allowing the cylinder to swing as it strokes. The body length A is 244 mm, the adjustable air cushion is 33 mm, and the standard PT1/2 ports supply filtered air at 0.15–1.0 MPa. Operating temperature range is -20 to +70 °C with the default TPU seals.

Where the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC200X80TC Is Used
Heavy Conveyor Diverters
Pivoting gate or diverter arms on wide conveyors where the trunnion mount lets the cylinder body swing through an arc while pushing a heavy steel flap.
Press-Frame Clamping
Clamping large weldments or castings in a hydraulic-style fixture, using the 15.7 kN push at 0.5 MPa to hold parts securely during machining or assembly.
Damper & Louver Actuation
Opening and closing large industrial dampers or louvers on dust-collection ductwork, where the centre trunnion mount accommodates the arc of the linkage.
Is the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC200X80TC the Right Cylinder?
Select the SC200 bore when your application needs roughly 15700 N of force at standard plant pressure. If the load is lighter, stepping down to the SC160 bore (10053 N at 0.5 MPa) can reduce air consumption and physical size. For strokes of 300 mm or longer, evaluate side-load and rod-bearing bending — an external guide or guided cylinder is recommended to protect the 40 mm rod and bearing.
To replace an existing cylinder, match five points: 200 mm bore, 80 mm stroke, PT port thread, centre trunnion (TC) mounting with TCM1 bracket, and no magnet. This SC 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 SC200X80TC FAQ
At 0.5 MPa the cylinder pushes with 15708 N and pulls with 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.
Yes — the TC suffix means the cylinder is supplied with a centre trunnion and the TCM1 bracket (F-SC200TC). This allows the cylinder body to pivot around the trunnion pins, making it suitable for swinging or arcing loads. Ensure the pivot pins are aligned and well-supported.
