About the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC250X900S
The AirTAC SC250X900S is a large-bore double-acting pneumatic cylinder delivering substantial push force for heavy industrial automation. At 0.5 MPa it generates 24544 N, rising to 44178 N at the maximum operating pressure of 0.9 MPa, making it suitable for pressing, clamping, and lifting large payloads.
This model features a 250 mm bore, 900 mm stroke, and a robust 50 mm diameter piston rod with M42x2 male threads. The built-in magnet allows direct mounting of CMSG/DMSG/EMSG sensors on the tie-rod barrel for non-contact position sensing. Adjustable air cushioning at both ends decelerates the high-inertia load smoothly over a 40 mm cushion length.

Where the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC250X900S Is Used
Heavy Pressing & Stamping
The 24544 N push force at 0.5 MPa drives large forming dies and stamping heads in metalworking and composite molding presses.
Pallet Lifting & Transfer
Lifts and transfers heavy palletized loads in material handling systems, using the 50 mm rod for stable, high-cycle vertical actuation.
Structural Test Rigs
Applies controlled, repeatable force in civil and mechanical test frames, with sensor feedback from the built-in magnet for precise stroke monitoring.
Is the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC250X900S the Right Cylinder?
For applications needing even higher force, a step up in bore is not available in the SC series, so consider parallel operation or a larger custom actuator. If 23562 N pull force at 0.5 MPa is sufficient but a smaller footprint is needed, the SC200 bore provides 15708 N push force. This 900 mm stroke model is within the standard 1500 mm maximum for the 250 bore.
For strokes of this length, the piston rod is susceptible to bending under side loads. Always guide the load externally with linear rails or rods, and never use the cylinder as a structural guide. When replacing, match the 250 mm bore, 900 mm stroke, PT1" port thread, basic mount, and the -S magnet option for sensor compatibility.
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 SC250X900S FAQ
At 0.5 MPa, push force is 24544 N and pull force is 23562 N. At the maximum operating pressure of 0.9 MPa, push force reaches 44178 N. The theoretical maximum at 1.0 MPa is 5006 kgf.
No. This is a double-acting cylinder that requires continuous air pressure to maintain position. If pressure is lost or the valve is centered, the piston will drift. For load holding, you must add an external rod lock or a pilot-operated check valve.
