About the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC250X100S
The SC250X100S is a large-bore double-acting tie-rod cylinder delivering 24544 N of push force at 0.5 MPa (up to 44178 N at 0.9 MPa). Its 50 mm diameter piston rod and 100 mm stroke suit heavy-duty clamping or pressing applications where space is constrained but force demands are high.
This model includes a built-in magnet (-S suffix), allowing CMSG, DMSG, or EMSG reed and solid-state sensors to be mounted directly on the barrel for piston position detection. The adjustable air cushion (40 mm length) decelerates the rod smoothly at stroke end, protecting the cylinder and tooling from impact damage.

Where the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC250X100S Is Used
Heavy-Duty Clamping
Generates up to 44178 N of clamping force at 0.9 MPa for securing large weldments or castings during machining, ensuring zero part movement under high cutting loads.
Press-Fit Assembly
The 50 mm rod and 100 mm stroke provide the rigidity and controlled force needed to press bearings, bushings, or pins into heavy housings on an assembly line.
Material Stop / Gate
With the built-in magnet for end-of-stroke sensing, this cylinder acts as a robust, high-force stop or diverter gate for pallets or heavy products on a conveyor system.
Is the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC250X100S the Right Cylinder?
Select the SC250 bore when your application requires between 24544 N (push at 0.5 MPa) and 44178 N (push at 0.9 MPa). If your force requirement is lower, stepping down to the SC200 bore provides 15708 N at 0.5 MPa, reducing air consumption and physical footprint. For a direct replacement, match bore (250 mm), stroke (100 mm), PT port thread, the built-in magnet (-S), and the basic mounting style. Note that as an ISO 6430 class cylinder, the maximum operating speed is 30-500 mm/s.
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 SC250X100S 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 increases to 44178 N. The theoretical maximum force at 1.0 MPa is 5006 kgf.
Yes. The -S suffix in the model code indicates a built-in magnet is installed on the piston. This allows you to directly clamp AirTAC CMSG, DMSG, or EMSG series sensors onto the cylinder barrel to detect piston position without any additional brackets.
