About the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC200X135S
The SC200X135S is a large-bore double-acting tie-rod cylinder delivering 15708 N push force at 0.5 MPa and up to 28274 N at 0.9 MPa operating pressure. With a 200 mm bore, 40 mm diameter piston rod, and a 135 mm stroke, it provides a compact yet powerful linear stroke for heavy industrial actuation.
This model includes a built-in magnet (-S suffix), allowing CMSG, DMSG, or EMSG reed and solid-state sensors to clamp directly onto the barrel for contactless position sensing. The body length A is 244 mm, giving a total extended length of approximately 379 mm. Adjustable air cushioning at both ends decelerates the 40 mm rod smoothly, protecting tooling during high-speed cycles.

Where the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC200X135S Is Used
Heavy Press & Clamping
Generates over 28000 N of thrust at 0.9 MPa for large-scale pressing, stamping, or die-clamping operations where consistent force is critical.
Material Handling Gates
Powers diverter gates and heavy chute doors in mining, aggregate, or bulk material handling with the 200 mm bore's high force reserve.
Steel Fabrication Jigs
Positions and locks heavy weldments or structural steel sections in fabrication jigs, with the built-in magnet enabling end-of-stroke confirmation via DMSG sensors.
Is the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC200X135S the Right Cylinder?
For applications needing more force, the SC250 bore delivers 24544 N push at 0.5 MPa. If a shorter body is required, step down to the SC160 bore (10053 N at 0.5 MPa). When replacing an existing cylinder, match five points: 200 mm bore, 135 mm stroke, PT port thread, basic mount (no bracket), and the built-in magnet (-S) for sensor compatibility.
At a 135 mm stroke, the 40 mm rod is well-supported within standard limits, but any side load should still be managed with an external guide or linear rail to prevent rod bearing wear and ensure long service life.
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 SC200X135S FAQ
At 0.7 MPa supply pressure, the push force is 21991 N. The theoretical maximum push force at the 1.0 MPa proof pressure is 3204 kgf, but the recommended operating range is 0.15–1.0 MPa.
Yes. The -S suffix indicates a built-in magnet in the piston. AirTAC CMSG (reed) or DMSG/EMSG (solid-state) sensors clamp directly onto the barrel tie-rods to detect piston position without additional brackets.
