About the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC250X1200S
The AirTAC SC250X1200-S is a double-acting tie-rod cylinder delivering a push force of 24544 N at 0.5 MPa and up to 44178 N at the maximum operating pressure of 0.9 MPa. Its 50 mm diameter piston rod and 40 mm adjustable air cushion are engineered for heavy-duty linear applications requiring a 1200 mm stroke within the standard range.
This model includes a built-in magnet (-S suffix), allowing CMSG, DMSG, or EMSG sensors to be mounted directly on the barrel for reliable, non-contact position sensing. The cylinder uses PT ports and standard TPU seals for operation in ambient temperatures from -20 to +70 °C.

Where the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC250X1200S Is Used
Heavy Press Tool Actuation
Provides the high force (up to 44178 N) needed to operate clamping and forming tools in large industrial presses.
Palletizer Pusher Systems
The 1200 mm stroke is ideal for pushing full pallet loads onto wrapping stations or conveyor lines in automated warehouses.
Large Valve Actuation
Delivers powerful linear motion for opening and closing heavy gate or butterfly valves in processing plants, with sensor feedback for position confirmation.
Is the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC250X1200S the Right Cylinder?
For applications needing slightly less force, the SC200 bore provides 15708 N at 0.5 MPa. When integrating this 1200 mm stroke cylinder, ensure the load is guided externally to prevent excessive side load on the 50 mm rod, which can cause bearing wear and rod bending. For replacement, match bore (250 mm), stroke (1200 mm), PT port thread, and the built-in magnet (-S) to ensure sensor 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 SC250X1200S FAQ
At 0.5 MPa, the push force is 24544 N and the pull force is 23562 N. The maximum push force at the 0.9 MPa operating limit is 44178 N.
Yes. The -S suffix indicates a built-in magnet, making it ready for AirTAC CMSG, DMSG, or EMSG reed and solid-state sensors to be clamped directly onto the barrel.
