About the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC200X25TC
The SC200X25TC is a large-bore, short-stroke double-acting cylinder from the AirTAC SC tie-rod series, delivering a substantial 15708 N of push force at just 0.5 MPa. With a 200 mm bore and a 25 mm stroke, it is built for applications that require immense clamping, pressing, or ejecting power within a very compact linear envelope.
This model features a 40 mm diameter piston rod, a 33 mm adjustable air cushion for smooth end-of-stroke deceleration, and a PT3/4 port. The TC suffix denotes a centre trunnion mounting configuration, supplied with the TCM1 bracket (part code F-SC200TC), allowing the cylinder to pivot and handle swinging loads effectively.

Where the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC200X25TC Is Used
Heavy-Duty Clamping
Generates over 15 kN of force at 0.5 MPa for secure workpiece holding in large welding fixtures or assembly jigs.
Short-Stroke Pressing
Ideal for high-force pressing, staking, or riveting operations where the working distance is minimal but the power requirement is extreme.
Pivoting Ejector Mechanism
The TC centre trunnion mount allows the cylinder to swing, making it suitable for actuating a heavy-duty ejector arm on a pivot.
Is the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC200X25TC the Right Cylinder?
Select the SC200X25TC when the task demands the highest force class in the SC range within a minimal stroke length. For applications needing slightly less force in a smaller package, consider stepping down to the 160 mm bore (10053 N at 0.5 MPa). The centre trunnion mount is ideal for pivoting applications, but ensure the load is guided to prevent side forces from acting on the rod.
For a direct replacement, match these five points: a 200 mm bore, a 25 mm stroke, a PT3/4 port thread, the TC centre trunnion mounting accessory, and the absence of a built-in magnet. This ensures dimensional and functional interchangeability with an existing AirTAC SC200 tie-rod cylinder.
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 SC200X25TC FAQ
At the standard operating pressure of 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 TC mount includes a trunnion bracket (TCM1) that clamps around the cylinder body, creating a central pivot point. This allows the entire cylinder to swing during operation, which is essential for applications where the connected load moves through an arc.
