About the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC200X650
The SC200X650 is a large-bore double-acting pneumatic cylinder delivering substantial 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 and a 650 mm stroke, it uses a robust 40 mm diameter piston rod with M36x2 threads and PT3/4 ports, making it suitable for heavy industrial actuation where high force is the primary requirement.
This tie-rod cylinder features an adjustable air cushion (33 mm length) at both ends to decelerate the piston smoothly, reducing impact and noise at the end of its travel. The total extended body length is approximately 894 mm (244 mm body length A + 650 mm stroke). It operates on filtered air within a standard temperature range of -20 to +70 °C using its default TPU seals.

Where the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC200X650 Is Used
Heavy Press & Forming
Provides the high force (up to 28274 N) needed for stamping, bending, or pressing operations in metal forming and heavy fabrication jigs.
Large-Scale Material Handling
Powers lifters, tippers, and heavy-duty conveyor diverters in warehouses and foundries, handling pallets or bulk materials with its 200 mm bore.
Industrial Clamping Systems
Delivers powerful, controlled clamping force for large workpieces in CNC machining centers, welding fixtures, and automated assembly lines.
Is the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC200X650 the Right Cylinder?
For applications requiring slightly less force, consider stepping down to the 160 mm bore SC160 series, which provides 10053 N of push force at 0.5 MPa. If your load demands exceed 15708 N at this pressure, the 250 mm bore SC250 series offers a significant jump to 24544 N. Always ensure the mounting and rod alignment are rigid, as side loads on the 40 mm rod can cause premature bearing wear and seal failure.
For this 650 mm stroke length, carefully evaluate any potential for side loading. Long, unsupported strokes on a single-rod cylinder are susceptible to rod bending and uneven bearing wear. If the load is not perfectly guided and linear, you must use an external guide rail system or switch to a guided cylinder to prevent damage and ensure consistent operation. To replace an existing unit, match the 200 mm bore, 650 mm stroke, PT3/4 port thread, basic mounting configuration, and the absence of a magnet sensor option exactly.
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 SC200X650 FAQ
The theoretical push force at 0.5 MPa is 15708 N, and the pull force is 15080 N. At the maximum operating pressure of 0.9 MPa, the push force increases to 28274 N. The absolute maximum theoretical force at 1.0 MPa is 3204 kgf.
No. The AirTAC SC series is a tie-rod cylinder and is physically shorter than a comparable ISO 15552 profile cylinder. It is not dimensionally interchangeable. It will only directly replace another AirTAC SC tie-rod cylinder with the same 200 mm bore, 650 mm stroke, PT port thread, and basic mounting.
