About the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC200X1550S
The AirTAC SC200X1550S is a double-acting tie-rod cylinder delivering 15708 N of push force at 0.5 MPa, scaling up to 28274 N at 0.9 MPa. With a 1550 mm stroke, this model exceeds the standard 1500 mm maximum, making it a made-to-order unit for applications needing extra reach. The 40 mm diameter piston rod and 33 mm adjustable air cushion work together to manage the high kinetic energy of a large-bore, long-stroke assembly.
This -S variant includes a built-in magnet, allowing CMSG, DMSG, or EMSG sensors to be mounted directly on the barrel for reliable end-of-stroke or mid-stroke position sensing. The total extended body length is approximately 1794 mm (body length A of 244 mm plus the 1550 mm stroke), so plan for substantial installation space. It uses PT ports and operates on filtered air from 0.15 to 1.0 MPa.

Where the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC200X1550S Is Used
Long-Reach Material Pusher
Provides the extended 1550 mm stroke needed to push heavy pallets or large sheet materials off a conveyor line, with sensor feedback confirming full extension and retraction.
Large Press Feed Ejector
Ejects formed parts from a large stamping press with 28274 N of force at 0.9 MPa. The built-in magnet allows sensors to verify the ejector has fully retracted before the next cycle.
Dock Leveler Actuation
Powers a heavy-duty hydraulic-style dock leveler using pneumatics, where the long stroke and high force are needed to raise the platform, and magnetic sensors ensure safe locking position.
Is the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC200X1550S the Right Cylinder?
Select the SC200 when your application requires forces in the 15708 N (0.5 MPa) to 28274 N (0.9 MPa) range. If your load is lighter, stepping down to a 160 mm bore reduces push force to 10053 N at 0.5 MPa, saving space and air consumption. For heavier demands, this is the largest standard SC bore.
At 1550 mm, this is a non-standard long stroke. Long, unsupported strokes on a single rod are vulnerable to side-load bending and rod bearing wear. Always use an external guide or a guided cylinder to absorb lateral forces, and ensure the rod is not subjected to off-axis loads. For replacement, match exactly: 200 mm bore, 1550 mm stroke, PT port thread, the built-in magnet (-S), and the basic mounting configuration.
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 SC200X1550S FAQ
At the standard 0.5 MPa operating pressure, the push force 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 theoretical maximum force at 1.0 MPa is 3204 kgf, but this exceeds the rated operating pressure.
No. A 1550 mm stroke with a 40 mm rod is highly susceptible to bending under side loads. An external guide rail or a guided cylinder must be used to prevent damage to the rod, bearings, and seals. The adjustable air cushion only decelerates the piston at end-of-stroke, it does not support side loads.
