About the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC250X750S
The SC250X750S is a heavy-duty double-acting tie-rod cylinder delivering 24544 N of push force at just 0.5 MPa and up to 44178 N at the maximum operating pressure of 0.9 MPa. With a 50 mm diameter piston rod and a 750 mm stroke, this model is built for large-scale industrial automation tasks requiring substantial linear thrust.
Equipped with a built-in magnet (-S suffix), the cylinder barrel accepts CMSG, DMSG, or EMSG reed and solid-state sensors for precise, non-contact position feedback. The body length A is 294 mm, and the total extended length reaches approximately 1044 mm. The adjustable air cushion (40 mm length) decelerates the piston smoothly at stroke ends, protecting the end caps during high-energy cycles.

Where the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC250X750S Is Used
Heavy Press Tool Actuation
Generates over 24 kN of force at 0.5 MPa to operate large forming dies, stamping presses, and heavy-duty clamping fixtures in metal fabrication lines.
Bulk Material Gate Control
Powers large slide gates or diverter chutes in mining, aggregate, and agricultural bulk handling systems, providing reliable operation in dusty environments.
Structural Test Rigs
Applies controlled, high-force linear loads for static and cyclic testing of beams, columns, and structural components in civil engineering laboratories.
Is the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC250X750S the Right Cylinder?
For applications needing slightly less force, the SC200 bore provides 15708 N push at 0.5 MPa, while stepping up is not possible within the SC family as 250 mm is the largest bore. At a 750 mm stroke, the 50 mm rod provides excellent column strength, but always verify side-load conditions—if the load is not guided externally, consider adding an external guide rail or switching to a guided cylinder to prevent rod bearing wear and bending. For a direct replacement, match the 250 mm bore, 750 mm stroke, PT port thread, basic mount, and the -S magnet option.
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 SC250X750S 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.
Yes. The -S suffix indicates a built-in magnet in the piston. This allows you to clamp compatible CMSG (reed) or DMSG/EMSG (solid-state) sensors directly onto the tie-rod barrel for end-of-stroke or intermediate position detection without additional brackets.
