About the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC200X450S
The SC200X450S 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 operating pressure. Its 40 mm diameter piston rod and 33 mm adjustable air cushion are engineered to manage high-inertia loads smoothly at the end of a 450 mm stroke.
This model includes a built-in magnet (-S suffix), allowing direct mounting of CMSG, DMSG, or EMSG reed and solid-state sensors on the barrel for non-contact position detection. The cylinder uses a PT1/2 port and standard TPU seals for a -20 to +70 °C working range, with a tie-rod construction that is shorter than an equivalent ISO 15552 profile.

Where the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC200X450S Is Used
Heavy Press Tool Actuation
Provides the 15708 N force at 0.5 MPa needed for clamping and forming in large stamping or die-casting presses, with sensor feedback confirming tool closure.
Palletizer & Conveyor Pushers
The 450 mm stroke and high push force efficiently transfer heavy pallets or bulk products across roller conveyors in automated logistics centers.
Construction Material Handling
Ideal for lifting and positioning heavy molds, concrete forms, or structural steel components, where the built-in magnet enables precise end-of-stroke sensing.
Is the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC200X450S the Right Cylinder?
For applications requiring slightly less force, the 160 mm bore SC160 series provides 10053 N push at 0.5 MPa. If more force is needed, the 250 mm bore SC250 delivers 24544 N at the same pressure. Always match bore, stroke, port thread (PT), and the magnet option (-S) when replacing an existing unit.
At a 450 mm stroke, ensure the rod is not subjected to significant side loading. The 40 mm rod is robust, but for offset or cantilevered loads, an external linear guide or a guided cylinder configuration is recommended to prevent rod bending and premature seal wear.
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 SC200X450S 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 force at 1.0 MPa is 3204 kgf.
Yes. The -S suffix in the model code SC200X450S indicates a built-in magnet. This allows you to clamp AirTAC CMSG, DMSG, or EMSG sensors directly onto the cylinder barrel to detect piston position without additional brackets.
