About the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC200X125S
The AirTAC SC200X125S is a double-acting tie-rod cylinder delivering 15708 N push force at 0.5 MPa and up to 28274 N at 0.9 MPa. Its 200 mm bore and 125 mm stroke suit medium-travel, high-force clamping and pressing operations where sensor feedback is required.
A built-in magnet (-S suffix) allows CMSG/DMSG/EMSG reed or solid-state sensors to mount directly on the barrel for end-of-stroke detection. The 40 mm diameter piston rod, PT3/4 port, and 33 mm adjustable air cushion provide robust deceleration. Body length A is 244 mm, giving a total extended length of approximately 369 mm.

Where the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC200X125S Is Used
Heavy Press & Forming
28274 N of force at 0.9 MPa drives metal forming, stamping, and heavy-duty pressing tools with sensor-confirmed cycle completion.
Automated Material Handling
Moves large pallets or heavy components on conveyors; the built-in magnet enables precise position sensing for automated transfer lines.
Test & Fatigue Rigs
Applies controlled, repeatable high-force loads in structural or material test stands, with sensor feedback ensuring accurate stroke end positioning.
Is the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC200X125S the Right Cylinder?
For a lower force in the same stroke, step down to the SC160 bore (10053 N push at 0.5 MPa). If more force is needed, the SC250 bore provides 24544 N at 0.5 MPa. When replacing, match five points: 200 mm bore, 125 mm stroke, PT port thread, the -S magnet for sensor compatibility, and the basic mounting configuration. This cylinder is a tie-rod design, not an ISO 15552 profile, so dimensional interchangeability is limited to other AirTAC SC200 tie-rod units.
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 SC200X125S FAQ
At 0.7 MPa operating pressure, the push force is 21991 N. The maximum push force at the 0.9 MPa upper limit is 28274 N, and the theoretical force at 1.0 MPa is 3204 kgf.
Yes. The -S suffix indicates a built-in magnet, so AirTAC CMSG (reed), DMSG, or EMSG (solid-state) sensors can be clamped directly onto the barrel to detect piston position without external brackets.
