About the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC250X850S
The SC250X850S is a large-bore double-acting pneumatic cylinder delivering substantial push force of 24544 N at 0.5 MPa, rising to 44178 N at the maximum operating pressure of 0.9 MPa. With an 850 mm stroke, it suits heavy industrial linear actuation tasks requiring significant power. This model includes a built-in magnet, allowing CMSG, DMSG, or EMSG sensors to be mounted directly on the tie-rod barrel for reliable end-of-stroke detection.
The 250 mm bore features a robust 50 mm diameter piston rod with an M42x2 knuckle thread and a PT1 inch port for high flow. Its adjustable air cushion (40 mm length) decelerates the piston smoothly at end-of-stroke, protecting the cylinder and load. The total body length A is 294 mm, giving an extended length of approximately 1144 mm. This is a genuine AirTAC SC tie-rod cylinder, engineered for demanding pneumatic systems.

Where the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC250X850S Is Used
Heavy Press & Forming
Provides up to 44178 N of force at 0.9 MPa for stamping, pressing, and metal forming operations, where consistent, high-force linear motion is critical.
Large-Scale Material Handling
Powers lifters, tippers, and transfer stations for heavy pallets or bulk materials, with the 850 mm stroke enabling full-range movement.
Structural Testing Rigs
Delivers controlled, high-force linear actuation for load testing of beams, joints, and structural components, with sensor feedback via the built-in magnet.
Is the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC250X850S the Right Cylinder?
Choose the SC250 for applications requiring the highest force output in the SC family, with 24544 N of push at 0.5 MPa. If your load requires less force, stepping down to the SC200 bore reduces push force to 15708 N at the same pressure, potentially saving space and air consumption. For strokes of 850 mm, ensure the load is guided and side forces are eliminated; the 50 mm rod, while robust, can be subject to bending moments under misaligned or unguided loads. Use external guides or a guided cylinder for long-stroke applications.
To ensure a direct replacement, match five key specifications: the 250 mm bore, 850 mm stroke, PT1 inch port thread, the built-in magnet (-S suffix), and the basic mounting configuration. This cylinder is a tie-rod design and is not dimensionally interchangeable with ISO 15552 profile cylinders; it replaces another AirTAC SC250 of identical configuration.
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 SC250X850S FAQ
At 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.
Yes. The -S suffix in the model code SC250X850S indicates a built-in magnet. This allows you to clamp compatible AirTAC CMSG, DMSG, or EMSG reed or solid-state sensors directly onto the cylinder's tie-rod barrel to detect piston position.
