About the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC200X950
The AirTAC SC200X950 is a large-bore double-acting tie-rod cylinder delivering a push force of 15708 N at 0.5 MPa and up to 28274 N at the maximum operating pressure of 0.9 MPa. With a 200 mm bore, 40 mm piston rod, and a 950 mm stroke, this model is built for heavy industrial linear motion tasks requiring substantial force over a long travel distance.
The cylinder body length A is 244 mm, resulting in a total extended length of approximately 1194 mm. It features a 33 mm adjustable air cushion at each end to decelerate the piston smoothly, reducing end-of-stroke impact. The standard PT3/4 port and M36x2 rod thread provide robust fluid and mechanical connections for demanding pneumatic circuits.

Where the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC200X950 Is Used
Heavy Press & Forming
Generates over 28000 N of force at 0.9 MPa for pressing, stamping, and forming operations in metal fabrication and composite molding.
Pallet & Load Transfer
Provides the long 950 mm stroke needed to push heavy pallets or transfer large components between conveyor lines in logistics and assembly plants.
Large-Scale Clamping
Ideal for clamping large workpieces, moulds, or structural assemblies in woodworking, welding fixtures, and heavy machining centres.
Is the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC200X950 the Right Cylinder?
For applications needing slightly less force, stepping down to the 160 mm bore SC160 series provides 10053 N of push force at 0.5 MPa. If the 28274 N maximum thrust at 0.9 MPa is insufficient, the 250 mm bore SC250 series offers 24544 N at 0.5 MPa. At a 950 mm stroke, the 40 mm rod is robust, but always evaluate side-loading conditions; long unsupported strokes can induce bending moments on the rod bearing. For guided or off-centre loads, pair this cylinder with an external linear guide or consider a guided cylinder configuration. To ensure a correct replacement, match the 200 mm bore, 950 mm stroke, PT3/4 port thread, basic mounting style, and the absence of a magnet option.
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 SC200X950 FAQ
At the standard operating pressure of 0.5 MPa, the push force is 15708 N and the pull force is 15080 N. At 0.7 MPa, the push force increases to 21991 N. The maximum operating force at 0.9 MPa is 28274 N.
No, the SC200X950 is a double-acting cylinder and will not hold its position if air pressure is exhausted or lost. The adjustable air cushion only decelerates the piston at the end of the stroke. To hold a load safely, you must use an external mechanical lock, a rod brake, or a pilot-operated check valve in the circuit.
