About the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC200X300S
The SC200X300S 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 the maximum operating pressure of 0.9 MPa. With a 40 mm diameter piston rod and a 33 mm adjustable air cushion, this 200 mm bore, 300 mm stroke actuator is built for heavy linear pushing and pulling tasks.
The built-in magnet (denoted by the -S suffix) allows direct mounting of CMSG, DMSG, or EMSG reed and solid-state sensors on the tie-rod barrel for reliable end-of-stroke or mid-stroke position feedback. Its PT3/4 port threads and M36x2 rod thread provide robust connections for high-flow pneumatic circuits.

Where the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC200X300S Is Used
Heavy Press Tool Actuation
Provides the high force (up to 28274 N at 0.9 MPa) needed to operate clamping fixtures and forming tools in large industrial presses, with sensor feedback for cycle confirmation.
Pallet Lifting and Transfer
Delivers the push and pull force for lifting heavy pallets in material handling systems. The built-in magnet enables precise position sensing to control lift height.
Large Valve Automation
Automates the opening and closing of large-diameter gate or butterfly valves in processing plants, using the 15708 N push force at standard line pressure for reliable operation.
Is the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC200X300S the Right Cylinder?
This 200 mm bore cylinder is a high-force solution. If your application requires less force, consider stepping down to the 160 mm bore (10053 N push at 0.5 MPa) or the 125 mm bore (6136 N push at 0.5 MPa). For strokes of 300 mm or more, ensure the load is guided externally; the 40 mm rod, while robust, can be subjected to bending moments if side loads are present. For direct replacement, match the 200 mm bore, 300 mm stroke, PT port thread, and the integrated magnet feature.
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 SC200X300S FAQ
At 0.7 MPa operating pressure, the SC200X300S generates a theoretical push force of 21991 N and a pull force of 15080 N. The maximum push force at 0.9 MPa is 28274 N.
Yes. The -S suffix indicates a built-in magnet is installed. You can clamp compatible AirTAC CMSG (reed) or DMSG/EMSG (solid-state) sensors directly onto the cylinder's tie-rod barrel to detect piston position without additional brackets.
