About the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC200X125TC
The SC200X125TC is a large-bore double-acting pneumatic cylinder delivering 15708 N of push force at 0.5 MPa, scaling up to 28274 N at the maximum operating pressure of 0.9 MPa. Its 125 mm stroke is paired with a robust 40 mm diameter piston rod and a 33 mm adjustable air cushion, providing smooth deceleration for heavy payloads.
This configuration includes a TC centre trunnion mount, supplied with the TCM1 bracket (F-SC200TC), allowing the cylinder to pivot and handle swinging loads. The body length A is 244 mm, and the PT3/4 port supplies ample flow for high-speed cycling in demanding industrial sequences.

Where the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC200X125TC Is Used
Heavy Press Tool Actuation
Provides up to 28274 N of force at 0.9 MPa for clamping and forming tools in large stamping presses, where the trunnion mount allows the cylinder to align with the press ram.
Swinging Gate or Damper Control
The centre trunnion mount is ideal for pivoting heavy dampers or gates in foundries and HVAC systems, absorbing the arc motion without side-loading the rod bearings.
Large-Format Lifting and Tipping
Delivers 15708 N at standard plant pressure to tip heavy bins or lift large platforms, with the adjustable cushion protecting the end caps from impact damage.
Is the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC200X125TC the Right Cylinder?
This 200 mm bore cylinder is a high-force actuator. If your application requires less force, stepping down to a 125 mm bore provides 6136 N at 0.5 MPa. For strokes of 125 mm, rod bearing stress is moderate, but always avoid direct side loads on the 40 mm rod; use an external guide system if the load is not perfectly axial.
For a correct replacement, match these five points: 200 mm bore, 125 mm stroke, PT3/4 port thread, TC centre trunnion mounting with TCM1 bracket, and the absence of a magnet. This ensures dimensional and functional interchangeability with another 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 SC200X125TC FAQ
At 0.5 MPa (approx. 5 bar), the push force is 15708 N. At 0.7 MPa it is 21991 N, and at the maximum operating pressure of 0.9 MPa it reaches 28274 N. The theoretical maximum at 1.0 MPa is 3204 kgf.
No. This is a standard double-acting cylinder and will drift or drop if pressure is exhausted or the directional valve is centered. To hold a load safely without live pressure, you must add an external rod brake, a mechanical lock, or a pilot-operated check valve.
