About the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC200X200SCB
The SC200X200SCB is a double-acting tie-rod cylinder delivering 15708 N push force at 0.5 MPa and up to 28274 N at 0.9 MPa operating pressure. Its 200 mm bore and 200 mm stroke suit heavy linear actuation where a pivoting mount is required, with a 40 mm diameter piston rod and PT3/4 port thread.
This configuration includes a built-in magnet (-S) for direct mounting of CMSG/DMSG/EMSG sensors, and a rear double clevis (CB) mount, part F-SC200CB, for articulated attachment. The adjustable air cushion (33 mm) decelerates the piston smoothly, and the standard TPU seals operate reliably from -20 to +70 °C.

Where the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC200X200SCB Is Used
Heavy Machinery Actuation
Provides the high force needed for lifting or tilting mechanisms on construction and agricultural equipment, with the CB clevis allowing free pivoting.
Large Press & Clamp Systems
Delivers up to 28274 N of clamping force at 0.9 MPa, ideal for industrial presses, holding large workpieces during welding or machining.
Material Handling Gates
Operates heavy diverter gates or chutes in mining and bulk material handling, where the rear clevis mount simplifies installation on pivoting structures.
Is the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC200X200SCB the Right Cylinder?
Choose the SC200 when your application needs the 15708 N push force at 0.5 MPa; stepping down to a 160 mm bore reduces that to 10053 N, while the 250 mm bore increases it to 24544 N. For this 200 mm stroke, the tie-rod construction provides robust support, but any side load should be managed with an external guide.
To replace an existing unit, match five points: 200 mm bore, 200 mm stroke, PT3/4 port thread, the CB rear double clevis mount, and the -S magnet for sensor compatibility. This ensures a direct dimensional and functional swap.
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 SC200X200SCB FAQ
At the standard 0.5 MPa operating pressure, the push force is 15708 N. At 0.7 MPa it reaches 21991 N, and at the maximum operating pressure of 0.9 MPa it delivers 28274 N. The theoretical maximum at 1.0 MPa is 3204 kgf.
No, the SC200X200SCB is a double-acting cylinder and will not hold position if pressure is exhausted or the directional valve is centered. The piston can drift or drop. For load holding without live pressure, you must add a pilot-operated check valve or an external mechanical rod lock.
