About the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC250X600S
The SC250X600S is a large-bore double-acting tie-rod cylinder delivering substantial push force of 24544 N at 0.5 MPa and up to 44178 N at the 0.9 MPa maximum operating pressure. With a 600 mm stroke and a robust 50 mm diameter piston rod, this model is built for heavy industrial linear actuation where high force and long travel are required.
Equipped with a built-in magnet (-S suffix), the cylinder allows direct mounting of CMSG, DMSG, or EMSG reed and solid-state sensors on the barrel for non-contact position feedback. The adjustable air cushion at each end decelerates the piston over a 40 mm cushion length, protecting the end caps from impact at high kinetic loads. The body length A is 294 mm, with a PT1 inch port for high flow.

Where the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC250X600S Is Used
Heavy Press & Forming
Provides the high tonnage force (up to 4.5 metric tons at 0.9 MPa) needed for hydraulic-pneumatic press tool actuation, metal forming, and heavy clamping fixtures.
Large-Scale Material Handling
Drives transfer carriages, lift tables, and heavy-duty pushers in steel mills, foundries, and large-scale warehouse automation, moving loads up to several tons.
Industrial Sawmill & Wood Processing
Actuates log kickers, heavy-duty positioning arms, and veneer press platens, with the built-in magnet sensor providing reliable end-of-stroke confirmation in dusty environments.
Is the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC250X600S the Right Cylinder?
For applications requiring slightly less force, stepping down to a 200 mm bore reduces push force to 15708 N at 0.5 MPa. If a 250 mm bore is necessary but the 600 mm stroke is insufficient, the SC250 supports standard strokes up to 1500 mm. At this 600 mm stroke, ensure the rod is protected from significant side loads; an external guide or a guided cylinder configuration is strongly recommended to prevent rod bending and premature bearing wear. When replacing an existing cylinder, match five key points: 250 mm bore, 600 mm stroke, PT1 inch port thread, the built-in magnet for sensor compatibility, 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 SC250X600S FAQ
At the standard 0.5 MPa operating pressure, the cylinder provides 24544 N pushing force and 23562 N pulling force. At the maximum operating pressure of 0.9 MPa, the pushing force increases to 44178 N. The theoretical maximum at 1.0 MPa is 5006 kgf.
Yes. The -S suffix in the model code SC250X600S indicates a built-in magnet along the piston. This allows you to directly clamp compatible AirTAC CMSG (reed) or DMSG/EMSG (solid-state) sensors onto the barrel's tie-rod slots to detect piston position without any additional mounting brackets.
