About the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC250X290
The AirTAC SC250X290 is a double-acting tie-rod cylinder delivering 24544 N of push force at 0.5 MPa and up to 44178 N at the maximum 0.9 MPa operating pressure. Its 290 mm stroke, combined with a massive 50 mm piston rod, provides robust linear thrust for heavy industrial tasks.
This model features adjustable pneumatic cushioning with a 40 mm cushion length to decelerate high-inertia loads and a body length A of 294 mm. The standard PT1" port thread ensures straightforward pneumatic connections. As an ISO 6430 class cylinder, it is engineered for demanding, high-force applications.

Where the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC250X290 Is Used
Heavy Press Tool Actuation
Provides the 44178 N maximum thrust at 0.9 MPa needed to operate large forming dies, stamping heads, or heavy-duty clamping fixtures in metal fabrication cells.
Pallet Lifting and Transfer
Delivers 24544 N of push force at 0.5 MPa to raise and transfer heavy pallets or engine blocks on end-of-line logistics systems, with a 290 mm stroke for vertical lift stations.
Structural Test Rigs
Applies controlled, high-force linear loads up to 44178 N for static and cyclic testing of large structural components, beams, or assemblies in civil engineering laboratories.
Is the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC250X290 the Right Cylinder?
Choose the SC250X290 when your application requires thrust in the 24 kN class at standard plant pressure. If a smaller footprint is acceptable, stepping down to the SC200 bore reduces push force to 15708 N at 0.5 MPa, while the SC250 remains the largest standard SC bore for maximum force density. For this 290 mm stroke, ensure the rod is not subjected to side loads; use an external guide or linear bearing to prevent rod bending and premature seal wear.
For a direct replacement, match five points: 250 mm bore, 290 mm stroke, PT1" port thread, basic mounting (no factory-fitted bracket), and the absence of a built-in magnet. This ensures full dimensional and performance interchangeability with another AirTAC SC250 tie-rod 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 SC250X290 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.
This specific SC250X290 model is supplied as a basic cylinder without factory-fitted mounting accessories. You can order mounting hardware separately, such as the TC centre trunnion (F-SC250TC with TCM1 bracket) or an LB foot mount (F-SC250LB), and attach them using the cylinder's tie-rod extensions.
