About the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC250X150S
The SC250X150S is a heavy-duty double-acting tie-rod cylinder delivering 24544 N of push force at 0.5 MPa (44178 N at the 0.9 MPa maximum operating pressure). Its 50 mm diameter piston rod and 40 mm adjustable air cushion make it suitable for large-scale industrial actuation where high force and controlled deceleration are required.
This model includes a built-in magnet (-S suffix), allowing CMSG, DMSG, or EMSG reed and solid-state sensors to clamp directly onto the barrel for contactless position sensing. With a body length A of 294 mm, the total extended length is approximately 444 mm. The standard PT1 inch port and M42x2 rod thread handle high flow rates for rapid cycling.

Where the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC250X150S Is Used
Heavy Press Tool Actuation
Provides the 24544 N push force at 0.5 MPa needed to operate large clamping fixtures and forming dies in metal stamping presses.
Bulk Material Gate Control
Controls heavy slide gates and diverter chutes in aggregate, grain, or mining material handling systems, with sensor feedback confirming open/closed position.
Structural Test Rigs
Applies high, repeatable loads for static and dynamic testing of large structural components, using the built-in magnet for precise stroke-end detection.
Is the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC250X150S the Right Cylinder?
For applications needing slightly less force, the SC200 bore provides 15708 N push at 0.5 MPa. When even higher force is required, confirm larger bore availability. The 150 mm stroke is well within the 1500 mm maximum standard stroke for bore 250. For side-load applications, consider an external guide or guided cylinder, as the 50 mm rod can experience bending under unsupported lateral forces.
To ensure a correct replacement, match five key points: 250 mm bore, 150 mm stroke, PT port thread, the built-in magnet (-S) for sensor compatibility, and any required mounting accessories. This ISO 6430 class cylinder is a direct replacement for an existing AirTAC SC250X150S or a tie-rod cylinder with identical specifications.
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 SC250X150S FAQ
At the standard 0.5 MPa operating pressure, 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 increases to 44178 N. The theoretical maximum force at 1.0 MPa is 5006 kgf.
Yes. The -S suffix in the model code SC250X150S indicates a built-in magnet. This allows you to mount AirTAC CMSG, DMSG, or EMSG series reed and solid-state sensors directly onto the cylinder barrel's tie-rod slots for non-contact position sensing.
