About the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC250X50S
The SC250X50S is a double-acting AirTAC tie-rod cylinder with a 250 mm bore and a short 50 mm stroke, equipped with a built-in magnet for barrel-mounted position sensors. At 0.5 MPa air pressure it generates 24544 N of push force, and at the maximum operating pressure of 0.9 MPa thrust climbs to 44178 N, placing it in the highest force class of the SC series.
This model features a 50 mm diameter piston rod with M42x2 knuckle threads and PT1" ports. The adjustable air cushion at each end has a 40 mm cushion length, and the standard TPU seals suit operating temperatures from -20 to +70 °C. The compact 50 mm stroke combined with the 294 mm body length A keeps the total extended length to just 344 mm for this high-force actuator.

Where the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC250X50S Is Used
Heavy Press Tool Actuation
The 24544 N push force at 0.5 MPa makes the SC250X50S ideal for short-stroke clamping and pressing in heavy-gauge metal forming tools, where the built-in magnet confirms jaw position.
Large Valve Positioning
Delivers high thrust over a precise 50 mm travel to actuate large industrial butterfly or gate valves. The magnetic piston allows end-of-travel sensing without external flag mounts.
Bulk Material Gate Control
Operates discharge gates on large silos and hoppers. The short stroke and high force shear sticky bulk materials, while the -S magnet provides reliable open/closed verification in dusty environments.
Is the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC250X50S the Right Cylinder?
Choose the SC250 bore when your application requires push forces above 20000 N at standard plant air pressure; the next step down is the SC200 bore delivering 15708 N push at 0.5 MPa. For this 50 mm stroke, side loading is rarely a concern, but always centre the load on the rod axis and avoid off-axis forces that can bend the 50 mm rod or score the front bearing.
To guarantee a correct replacement, match five points: 250 mm bore, 50 mm stroke, PT1" port thread, the built-in magnet (-S suffix) for CMSG/DMSG/EMSG sensor compatibility, and the basic mounting configuration. This cylinder is not an ISO 15552 profile unit; it is a tie-rod design that is shorter than an equivalent ISO cylinder.
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 SC250X50S FAQ
At 0.5 MPa, push force is 24544 N and pull force is 23562 N. At 0.7 MPa, push force reaches 34361 N. The maximum operating push force at 0.9 MPa is 44178 N. The theoretical maximum at 1.0 MPa is 5006 kgf.
Yes. The -S suffix in the model code indicates a built-in magnet on the piston. This allows you to clamp AirTAC CMSG (reed) or DMSG/EMSG (solid-state) sensors directly onto the tie-rod barrel to sense end-of-stroke or intermediate positions.
