About the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC200X175TC
The AirTAC SC200X175TC is a large-bore double-acting pneumatic cylinder delivering substantial push force of 15708 N at 0.5 MPa and up to 28274 N at 0.9 MPa. With a 200 mm bore, 40 mm piston rod, and a 175 mm stroke, this model is supplied with a centre trunnion (TC) mount for applications requiring the cylinder body to pivot during operation.
This tie-rod cylinder features an adjustable pneumatic cushion (33 mm length) to decelerate the piston smoothly at end-of-stroke, reducing impact and vibration. The standard PT3/4 port thread and M36x2 rod thread ensure robust connections, while the TPU seals provide reliable operation within a -20 to +70 °C temperature range.

Where the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC200X175TC Is Used
Heavy Press & Clamping
Generates up to 28274 N of force at 0.9 MPa for industrial pressing, stamping, or heavy-duty clamping fixtures where a pivoting cylinder body is required.
Swinging Gate or Diverter
The centre trunnion mount allows the cylinder to pivot, making it suitable for actuating large swinging gates, chute diverters, or material handling flippers.
Large-Scale Lifting & Tilting
Provides the muscle for tilting heavy bins, lifting platforms, or positioning large weldments, with the trunnion absorbing the angular movement of the load.
Is the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC200X175TC the Right Cylinder?
Selecting the SC200X175TC means choosing a 200 mm bore for high-force tasks. If your application requires less force, consider stepping down to the 160 mm bore (10053 N push at 0.5 MPa). For even higher force, the 250 mm bore provides 24544 N at the same pressure. The centre trunnion mount (TC, part F-SC200TC) allows the cylinder to swing, making it ideal for pivoting loads, but ensure the trunnion pins are aligned and supported to handle the reaction forces.
For replacement, match these five points exactly: 200 mm bore, 175 mm stroke, PT port thread, centre trunnion (TC) mounting, and the absence of a magnet. This is a tie-rod cylinder, not an ISO 15552 profile, so dimensional interchangeability is limited to another AirTAC SC200 or an equivalent tie-rod design.
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 SC200X175TC FAQ
At 0.7 MPa operating pressure, this 200 mm bore cylinder generates a theoretical push force of 21991 N. The pull force on the retract stroke is 15080 N, accounting for the area reduction from the 40 mm piston rod.
No, the SC200X175TC is a double-acting cylinder and does not hold position when air pressure is lost or the valve is centered. The adjustable air cushion only decelerates the piston at stroke end. For load holding, an external rod lock or pilot-operated check valve is required.
