About the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC200X170TC
The AirTAC SC200X170TC is a large-bore double-acting pneumatic cylinder delivering substantial force for heavy industrial automation. With a 200 mm bore operating at 0.5 MPa, it generates 15708 N of push force, scaling up to 28274 N at the maximum 0.9 MPa operating pressure, making it suitable for pressing, clamping, and lifting heavy loads.
This model features a 170 mm stroke with a 40 mm diameter piston rod and M36x2 rod thread for robust connection. It comes equipped with a TC centre trunnion mount (supplied with TCM1 bracket, part code F-SC200TC) for pivoting applications, adjustable air cushioning to decelerate the 40 mm rod and load, and standard PT3/4 ports.

Where the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC200X170TC Is Used
Heavy Pressing & Forming
Generates up to 28274 N of force at 0.9 MPa for stamping, bending, or forming operations in metal fabrication cells.
Pivoting Material Handling
The TC centre trunnion mount allows the cylinder to swing, making it perfect for actuating diverters or lift gates on heavy-duty conveyor systems.
Large Valve Actuation
Provides the high thrust needed to operate large butterfly or ball valves in water treatment, chemical, or power generation plants.
Is the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC200X170TC the Right Cylinder?
Choose the SC200 for force requirements between the SC160 (10053 N push at 0.5 MPa) and the SC250 (24544 N push at 0.5 MPa). The TC centre trunnion mount allows the cylinder body to pivot, ideal for swinging or articulating loads. For direct replacement, match bore (200 mm), stroke (170 mm), PT port thread, TC mounting, and the absence of a magnet. Ensure the rod is externally guided if side loads are present, as the 40 mm rod is designed for axial thrust, not bending moments.
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 SC200X170TC 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, push force reaches 28274 N. The theoretical maximum at 1.0 MPa is 3204 kgf.
No. The SC200 is a standard double-acting cylinder and will not hold position if air pressure is lost or the directional valve is centered. The piston will drift. For load holding, you must add an external rod lock, brake, or a pilot-operated check valve.
