About the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC200X450SCB
The SC200X450SCB is a double-acting tie-rod cylinder delivering 15708 N of push force at 0.5 MPa and up to 28274 N at 0.9 MPa, making it suitable for heavy pressing and clamping operations. With a 200 mm bore and 450 mm stroke, this model features a 40 mm piston rod, PT1/2 ports, and a 33 mm adjustable air cushion to decelerate high-inertia loads smoothly.
This configuration includes a built-in magnet (-S) for mounting CMSG/DMSG/EMSG sensors directly on the barrel, and a rear double clevis (CB) mount with part code F-SC200CB for pivoting applications. The standard TPU seals provide reliable operation from -20 to +70 °C, and the total extended body length is approximately 694 mm.

Where the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC200X450SCB Is Used
Heavy-Duty Press Frames
Generates over 28000 N at 0.9 MPa for stamping, riveting, and assembly presses requiring consistent, high clamping force.
Large Part Ejection
The 450 mm stroke ejects large plastic or metal parts from moulds, with the CB clevis allowing the cylinder to pivot as the tool opens.
Material Handling Gates
Controls heavy diverter gates and chutes in mining or aggregate handling, where the double clevis mount handles misalignment and the magnet confirms position.
Is the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC200X450SCB the Right Cylinder?
Choose the SC200 bore when your application needs between 15708 N and 28274 N of force; if you can work with less, stepping down to the SC160 bore saves space and weight while still providing 10053 N at 0.5 MPa. For strokes of 450 mm, ensure the rod is adequately guided—side loads on an unsupported 40 mm rod can cause bending and premature seal wear. For replacement, match the 200 mm bore, 450 mm stroke, PT1/2 port thread, CB rear double clevis mount, and the integrated magnet sensor option.

- ✓ 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 SC200X450SCB 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, the push force reaches 28274 N. The theoretical maximum at 1.0 MPa is 3204 kgf.
No. The SC200 is a double-acting cylinder and will drift or drop if pressure is lost or the directional valve is centered. To hold a load safely without live pressure, you must add a pilot-operated check valve, external rod lock, or mechanical brake.
