About the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC250X950
The AirTAC SC250X950 is a large-bore double-acting tie-rod cylinder delivering a substantial push force of 24544 N at 0.5 MPa (max theoretical 5006 kgf at 1.0 MPa). With a 250 mm bore and a 950 mm stroke, this model is built for heavy industrial linear motion where high force and long travel are essential.
The cylinder uses a 50 mm diameter piston rod with an M42x2 knuckle thread and a PT1" port. Its body length A is 294 mm, giving a total extended length of approximately 1244 mm. The 40 mm adjustable air cushion at each end decelerates the high-inertia load smoothly, protecting the end caps from impact damage. This is a genuine AirTAC SC series unit, factory assembled with TPU/NBR seals for a standard operating temperature range of -20 to +70 °C.

Where the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC250X950 Is Used
Heavy Press & Forming
The 24544 N push force at 0.5 MPa operates large clamping fixtures, bending presses, and heavy-gauge forming tools in metal fabrication cells.
Bulk Material Handling
Drives large diverter gates, chute doors, and hopper slides in mining, aggregate, and agricultural processing, handling high material loads with the 950 mm stroke.
Structural Testing Rigs
Applies controlled, high-force linear motion for load testing of structural components, beams, and large assemblies in civil engineering laboratories.
Is the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC250X950 the Right Cylinder?
Select the SC250 when your application requires push forces in the 24-44 kN class at standard air pressures. If 24544 N at 0.5 MPa exceeds your need, step down to the SC200 bore, which provides 15708 N at the same pressure and uses a lighter 40 mm rod. For any stroke of 300 mm or more, and especially at 950 mm, the rod bearing must be protected from side loads; an external guide or a guided cylinder is strongly recommended to prevent rod bending and premature seal wear.
To guarantee a drop-in replacement, match five key points: the 250 mm bore, the 950 mm stroke, the PT1" port thread, the basic (no bracket) mounting configuration, and the absence of a built-in magnet. This model does not include a magnet, so if you need barrel-mounted sensors, specify the -S suffix on your next order.
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 SC250X950 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.
No. The SC250X950 is a double-acting cylinder and will not hold its position if pressure is exhausted or the directional valve is centered. For load holding, you must add an external rod brake, a mechanical lock, or a pilot-operated check valve.
