About the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC200X250S
The SC200X250S is a large-bore double-acting pneumatic cylinder delivering 15708 N of push force at 0.5 MPa and up to 28274 N at the maximum operating pressure of 0.9 MPa. With a 250 mm stroke and a rigid 40 mm diameter piston rod, this model is built for heavy linear actuation tasks where position sensing is required, thanks to the integrated magnet.
This tie-rod cylinder features a 33 mm adjustable air cushion at each end to decelerate high-inertia loads smoothly. The body length A is 244 mm, resulting in a total extended length of approximately 494 mm. It uses a PT1/2 port and an M36x2 rod thread, operating reliably on filtered air within a -20 to +70 °C temperature range.

Where the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC200X250S Is Used
Heavy Material Handling
Powers lift tables and large part pushers in foundries and steel plants, where the 15708 N force at 0.5 MPa easily moves multi-ton loads.
Large Press Tool Actuation
Operates clamping and stripping plates in large hydraulic-style press tools converted to pneumatics, with magnetic sensors confirming safe tool closure.
Forestry & Agricultural Machinery
Controls heavy chute gates and log kickers on harvesters and processing lines, benefiting from the tie-rod construction's serviceability in the field.
Is the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC200X250S the Right Cylinder?
For applications needing slightly less force, stepping down to a 160 mm bore reduces push force to 10053 N at 0.5 MPa, while stepping up to a 250 mm bore increases it to 24544 N. Always match the bore, 250 mm stroke, PT port thread, and the -S magnet option when replacing an existing unit.
At this 250 mm stroke, the 40 mm rod is robust, but any significant side loading still demands an external guide or a guided cylinder configuration to prevent rod bearing wear and bending. The built-in magnet allows direct mounting of CMSG, DMSG, or EMSG sensors on the barrel for electrical end-of-stroke confirmation.
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 SC200X250S FAQ
At 0.5 MPa, 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 reaches 28274 N. The theoretical maximum force at 1.0 MPa is 3204 kgf.
Yes. The -S suffix in the model code indicates a built-in magnet is factory-installed in the piston. This allows you to clamp compatible AirTAC CMSG, DMSG, or EMSG reed or solid-state sensors directly onto the barrel tie-rods to detect piston position.
