About the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC200X20
The AirTAC SC200X20 is a double-acting tie-rod cylinder delivering a substantial 15708 N of push force at 0.5 MPa, ideal for short-throw clamping and pressing tasks. With a 40 mm diameter piston rod and PT3/4 ports, this model handles high-force applications in a compact 20 mm stroke envelope.
Built with a 244 mm body length (A dimension), the SC200X20 uses an adjustable air cushion to decelerate the piston smoothly at end of travel. The TPU seals provide reliable operation from -20 to +70 °C, making it a robust choice for industrial automation requiring precise, short linear movements.

Where the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC200X20 Is Used
Heavy-Duty Clamping
Applies 15.7 kN of clamping force at 0.5 MPa for securing large workpieces during machining or welding operations.
Short-Stroke Pressing
Executes precise 20 mm pressing actions in assembly fixtures, delivering high force in a minimal footprint.
Material Stops
Acts as a robust end-stop on heavy-duty conveyors, halting pallets or large components with controlled deceleration.
Is the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC200X20 the Right Cylinder?
For applications needing slightly less force, the SC160 bore delivers 10053 N push at 0.5 MPa. If a longer stroke is required, the SC200 supports strokes up to 1500 mm. When replacing an existing cylinder, ensure an exact match on bore (200 mm), stroke (20 mm), PT port thread, basic mounting, and the absence of a magnet sensor option to guarantee drop-in compatibility.
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 SC200X20 FAQ
The SC200X20 generates 15708 N of push force and 15080 N of pull force when operated at 0.5 MPa air pressure.
No, the SC200X20 is a double-acting cylinder and will not hold position without live air pressure. The piston can drift or drop if pressure is lost. For load holding, an external rod lock or pilot-operated check valve is required.
