About the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC250X110
The SC250X110 is a large-bore double-acting tie-rod cylinder delivering substantial push force of 24544 N at 0.5 MPa (up to 44178 N at 0.9 MPa). With a 250 mm bore and 110 mm stroke, this model is built for heavy industrial applications where high force in a compact stroke is essential, such as pressing, clamping, and lifting heavy tooling.
This cylinder features a 50 mm diameter piston rod with M42x2 male threads and a PT1" port. The total extended body length is approximately 404 mm (294 mm body length A plus 110 mm stroke). It includes an adjustable pneumatic cushion (40 mm length) to decelerate the piston smoothly, reducing end-of-stroke impact. This is an ISO 6430 class cylinder, suitable for demanding, high-force automation tasks.

Where the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC250X110 Is Used
Heavy-Duty Pressing
Generates up to 44178 N of force at 0.9 MPa for stamping, riveting, or compacting operations in assembly lines.
Industrial Clamping
Provides a rigid 24544 N holding force at 0.5 MPa to secure large workpieces on CNC machining centers or welding fixtures.
Material Lifting & Hoisting
The 50 mm rod and 250 mm bore deliver stable, high-force vertical actuation for lifting heavy dies or engine blocks in maintenance bays.
Is the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC250X110 the Right Cylinder?
Select the SC250X110 when your application requires a force class around 24544 N at standard plant pressure. If you need slightly less force in a smaller envelope, the SC200 bore provides 15708 N push at 0.5 MPa. For strokes of 110 mm, side-loading is typically not a primary concern on a 50 mm rod, but always ensure the load is guided externally if any lateral force is present to prevent rod bearing wear. For a direct replacement, match the 250 mm bore, 110 mm stroke, PT1" port thread, basic mounting configuration, and confirm the tie-rod mounting dimensions are identical to the existing AirTAC SC 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 SC250X110 FAQ
At the standard operating pressure of 0.5 MPa, the push force is 24544 N and the pull force is 23562 N. At the maximum operating pressure of 0.9 MPa, the push force reaches 44178 N. The theoretical maximum force at 1.0 MPa is 5006 kgf.
No. The AirTAC SC series is a tie-rod cylinder that is physically shorter than a comparable ISO 15552 profile cylinder. For large bores (125-250), it aligns with the ISO 6430 class for mounting dimensions, but it is not a drop-in replacement for an ISO 15552 unit. Always verify the body length A (294 mm) and mounting hole patterns against your existing setup.
