About the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC200X375S
The AirTAC SC200X375S is a double-acting single-rod tie-rod cylinder delivering 15,708 N of push force at just 0.5 MPa, scaling to 28,274 N at the maximum operating pressure of 0.9 MPa. With a 200 mm bore and a 375 mm stroke, this model includes a built-in magnet (-S suffix) that allows CMSG, DMSG, or EMSG reed and solid-state sensors to clamp directly onto the barrel for contactless position sensing.
The 40 mm diameter piston rod and 33 mm adjustable air cushion at each end provide robust deceleration for heavy payloads. The body length A is 244 mm, giving a total extended length of approximately 619 mm. Operating on filtered air from 0.15 to 1.0 MPa, this cylinder uses standard PT ports (PT3/4) and TPU seals for a temperature range of -20 to +70 °C.

Where the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC200X375S Is Used
Heavy Pallet Lifting
Raises and lowers loaded pallets in automated storage and retrieval systems, where the 15.7 kN force at 0.5 MPa easily handles multi-ton loads with position feedback from the magnetic piston.
Large Press & Clamping
Provides the high clamping force needed for large-scale assembly presses or welding fixtures. The built-in magnet enables end-of-stroke confirmation to ensure the tool is fully closed before the cycle starts.
Damper & Gate Actuation
Operates heavy slide gates or dampers in bulk material handling. The 33 mm adjustable cushion absorbs the kinetic energy of the large mass at the end of the 375 mm travel, protecting the cylinder and structure.
Is the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC200X375S the Right Cylinder?
For applications needing slightly less force, the 160 mm bore SC160 series offers 10,053 N push at 0.5 MPa, while stepping up to the 250 mm bore SC250 provides 24,544 N at the same pressure. At a 375 mm stroke, ensure the rod is not subjected to high side loads; if the load is not guided externally, consider adding an external linear guide or switching to a guided cylinder to prevent rod bearing wear and bending.
When replacing an existing cylinder, match five key points: 200 mm bore, 375 mm stroke, PT3/4 port thread, the built-in magnet for sensor mounting, and the basic (no bracket) mounting configuration. This SC model is a tie-rod design and is not dimensionally interchangeable with ISO 15552 profile cylinders.
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 SC200X375S FAQ
At 0.5 MPa, the push force is 15,708 N and the pull force is 15,080 N. At the maximum operating pressure of 0.9 MPa, push force reaches 28,274 N. The theoretical maximum force at 1.0 MPa is 3,204 kgf.
Yes. The -S suffix in SC200X375S indicates a built-in magnet on the piston. This allows you to clamp AirTAC CMSG (reed) or DMSG/EMSG (solid-state) sensors directly onto the barrel tie-rods to detect piston position without additional brackets.
