About the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC200X300TC
The AirTAC SC200X300TC is a large-bore double-acting tie-rod cylinder delivering 15708 N of push force at 0.5 MPa, rising to 28274 N at the maximum operating pressure of 0.9 MPa. With a 300 mm stroke and a 40 mm diameter piston rod, this model is built for heavy industrial tasks requiring substantial linear thrust.
This specific configuration includes a centre trunnion (TC) mount, supplied with the TCM1 bracket (F-SC200TC), allowing the cylinder to pivot and accommodate angular motion during operation. The body length A is 244 mm, and the standard PT 3/4 port provides reliable pneumatic connections for high-flow applications.

Where the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC200X300TC Is Used
Heavy Press Tool Actuation
Provides the high clamping and pressing forces required for large forming, stamping, or laminating presses in metal and composite fabrication.
Bulk Material Gate Control
Operates heavy slide gates or diverter valves in silos and hoppers, where the pivoting trunnion mount accommodates structural movement and misalignment.
Construction Equipment Fixtures
Powers robust positioning jigs and lifting arms in heavy machinery manufacturing, leveraging the 28274 N maximum thrust for demanding assembly tasks.
Is the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC200X300TC the Right Cylinder?
For applications needing slightly less force, stepping down to a 160 mm bore reduces push force to 10053 N at 0.5 MPa. At a 300 mm stroke on a 40 mm rod, ensure side loads are minimal; if the load is not guided externally, consider adding a guide rod assembly to prevent rod bending and premature bearing wear. When replacing an existing cylinder, match all five critical points: 200 mm bore, 300 mm stroke, PT 3/4 port thread, centre trunnion (TC) mount with TCM1 bracket, and the absence of a built-in magnet.
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 SC200X300TC 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 increases to 28274 N. The theoretical maximum force at 1.0 MPa is 3204 kgf.
No. The SC200X300TC is a double-acting cylinder and will not hold its position if air pressure is lost or the directional valve is centered. For load-holding applications, you must use an external mechanical lock, a rod brake, or a pilot-operated check valve.
