About the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC200X120S
The SC200X120S is a double-acting tie-rod cylinder delivering 15708 N push force at 0.5 MPa, scaling up to 28274 N at the maximum operating pressure of 0.9 MPa. With a 200 mm bore and 120 mm stroke, this actuator uses a 40 mm diameter piston rod and M36x2 rod thread, providing robust linear thrust for heavy industrial tasks.
This model includes the -S suffix, equipping the cylinder with a built-in magnet. This allows CMSG, DMSG, or EMSG reed and solid-state sensors to be mounted directly onto the barrel for reliable, non-contact end-of-stroke detection. The total extended body length is approximately 364 mm, and the adjustable pneumatic cushion (33 mm length) decelerates the piston smoothly at each end of travel.

Where the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC200X120S Is Used
Heavy Material Handling
Provides the high push force needed for lifting, tilting, or transferring heavy pallets and steel components in automated logistics systems.
Large Press & Clamping
Delivers up to 28274 N of clamping force for large-scale assembly presses, welding fixtures, and die-casting operations, with sensor confirmation of jaw position.
Agricultural Machinery Actuation
Powers the robust linear movements on heavy farm equipment like bale handlers or large chute gates, with the magnet enabling position feedback to the control system.
Is the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC200X120S the Right Cylinder?
Choose the SC200X120S for high-force applications where sensor feedback is required. If your load requires less force, stepping down to the 125 mm bore (6136 N push at 0.5 MPa) can reduce air consumption and physical size. For even greater thrust, the 250 mm bore model provides 24544 N at 0.5 MPa.
To ensure a correct replacement, match five key points: 200 mm bore, 120 mm stroke, PT port thread, the built-in magnet (-S), and the basic mounting style. The 40 mm rod is robust, but for strokes over 300 mm or applications with significant side load, always use an external guide or a guided cylinder to protect the rod bearing from bending stress.
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 SC200X120S FAQ
At 0.5 MPa, the cylinder produces 15708 N pushing and 15080 N pulling. The force increases to 21991 N push at 0.7 MPa, and reaches a maximum of 28274 N push at the 0.9 MPa operating limit.
Yes. The -S suffix indicates a built-in magnet, making it compatible with AirTAC CMSG, DMSG, and EMSG sensors. These sensors clamp directly onto the tie-rod barrel to detect piston position without physical contact.
