About the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC250X300S
The AirTAC SC250X300S is a double-acting, single-rod tie-rod cylinder delivering substantial force for heavy-duty industrial automation. With a 250 mm bore and 300 mm stroke, it generates 24544 N of push force at 0.5 MPa and up to 44178 N at the maximum operating pressure of 0.9 MPa, making it suitable for pressing, clamping, and lifting large payloads.
This model includes a built-in magnet (-S suffix), allowing direct mounting of CMSG, DMSG, or EMSG reed and solid-state sensors on the barrel for contactless position feedback. The piston rod is 50 mm in diameter with an M42x2 knuckle thread, and the cylinder features a 40 mm adjustable air cushion at each end to decelerate high-inertia loads smoothly. The body length A is 294 mm, resulting in a total extended length of approximately 594 mm.

Where the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC250X300S Is Used
Heavy Pressing & Forming
Delivers up to 44178 N at 0.9 MPa for stamping, riveting, and material forming operations requiring high force in a compact stroke.
Palletising & Bulk Handling
Provides the thrust to lift and position heavy pallets or bulk containers in automated logistics and warehouse systems.
Large Valve Actuation
Operates large quarter-turn valves or dampers in process industries, with the built-in magnet enabling reliable open/closed position sensing.
Is the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC250X300S the Right Cylinder?
Select the SC250 when your application requires force in the 24 kN range at 0.5 MPa; if you need less force, the SC200 bore provides 15708 N at the same pressure. For strokes of 300 mm or more on this 50 mm rod, ensure the load is guided externally—long unsupported rods are susceptible to bending under side loads. For replacement, match five points exactly: 250 mm bore, 300 mm stroke, PT port thread, the built-in magnet (-S), and the basic mounting configuration. This is an ISO 6430 class tie-rod cylinder, not an ISO 15552 profile unit.
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 SC250X300S FAQ
At 0.7 MPa operating pressure, the SC250X300S generates a theoretical push force of 34361 N. The pull force on the retract stroke is 23562 N at 0.5 MPa, reduced by the 50 mm rod area.
Yes. The -S suffix indicates a built-in magnet, so AirTAC CMSG (reed) or DMSG/EMSG (solid-state) sensors clip directly onto the barrel's sensor groove for non-contact position detection.
