About the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC250X200S
The AirTAC SC250X200S is a robust double-acting tie-rod cylinder delivering a substantial push force of 24544 N at 0.5 MPa, scaling up to a powerful 44178 N at the maximum operating pressure of 0.9 MPa. With a 200 mm stroke and a 50 mm diameter piston rod, this cylinder is built for heavy-duty industrial tasks where high force is non-negotiable.
This model features a built-in magnet, enabling the direct mounting of CMSG, DMSG, or EMSG sensors along the barrel for precise, non-contact position feedback. The adjustable pneumatic cushion at each end, with a 40 mm cushion length, effectively decelerates the large moving mass, protecting the end caps from impact damage.

Where the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC250X200S Is Used
Heavy Pressing & Forming
Provides the extreme force needed in hydraulic replacement scenarios for pressing, stamping, and metal forming operations within its 1.0 MPa rating.
Large-Scale Material Handling
Operates heavy-duty pushers and transfer systems in steel mills or foundries, moving large billets or sheets with its 24544 N push at standard pressure.
Automated Heavy Assembly
Used in large engine or heavy equipment assembly lines for pressing bearings, gears, or bushings with precise, sensor-monitored stroke control.
Is the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC250X200S the Right Cylinder?
For applications requiring slightly less force, consider stepping down to the SC200 bore, which provides 15708 N of push force at 0.5 MPa. This SC250X200S is an ISO 6430 class cylinder, and its 50 mm rod is designed for substantial axial loads; however, for any application involving side loads or a long unsupported stroke, an external guide system is essential to prevent rod bending and premature seal wear. To ensure a correct replacement, match five key points: the 250 mm bore, 200 mm stroke, PT port thread, the built-in magnet option (-S), and the basic mounting style.
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 SC250X200S FAQ
At 0.5 MPa (5 bar), 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 increases to 44178 N. The theoretical maximum force at1.0 MPa is 5006 kgf.
Yes. The '-S' suffix in the model code SC250X200S indicates a built-in magnet in the piston. This allows you to clamp compatible AirTAC CMSG (reed) or DMSG/EMSG (solid-state) sensors directly onto the tie-rod barrel for end-of-stroke detection.
