About the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC200X50S
The SC200X50S is a large-bore double-acting tie-rod cylinder delivering a substantial 15708 N of push force at just 0.5 MPa, rising to 28274 N at the maximum operating pressure of 0.9 MPa. With a 50 mm stroke and a robust 40 mm diameter piston rod, this model is built for short, powerful linear movements in heavy-duty industrial applications.
The built-in magnet, designated by the 'S' suffix, allows for direct mounting of CMSG, DMSG, or EMSG reed and solid-state sensors on the barrel for precise, non-contact position sensing. Its 33 mm adjustable air cushion at each end effectively decelerates the high inertial loads typical of a 200 mm bore cylinder, protecting the end caps from impact damage.

Where the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC200X50S Is Used
Heavy Press & Stamping
Provides up to 28274 N of force at 0.9 MPa for short-stroke clamping, punching, and stamping operations where high force density in a compact footprint is critical.
Automated Welding Fixtures
The built-in magnet and sensor compatibility allow for precise end-of-stroke confirmation, ensuring clamps are fully engaged before a robotic welding cycle begins.
Material Stop & Transfer
Ideal for stopping or diverting heavy pallets and loads on conveyor lines, using the short 50 mm stroke for a fast, decisive action with adjustable cushioning.
Is the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC200X50S the Right Cylinder?
For applications requiring slightly less force, the 160 mm bore SC160 series provides 10053 N of push force at 0.5 MPa. Always match a replacement cylinder on all five critical points: 200 mm bore, 50 mm stroke, PT port thread, the basic mounting configuration, and the built-in magnet (-S) for sensor compatibility. This is not an ISO 15552 cylinder; it is a tie-rod design with a body length of 244 mm, making it shorter than an equivalent ISO profile cylinder.
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 SC200X50S FAQ
At the standard 0.5 MPa operating pressure, this cylinder provides 15708 N of push force and 15080 N of pull force. At the maximum operating pressure of 0.9 MPa, the push force increases to 28274 N. The theoretical maximum force at 1.0 MPa is 3204 kgf.
Yes. The 'S' in the model code SC200X50S confirms a built-in magnetic piston. This allows you to clamp AirTAC CMSG, DMSG, or EMSG sensors directly onto the cylinder barrel's tie-rod slots for reliable, non-contact position feedback without any additional brackets.
