About the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC200X30STC
The AirTAC SC200X30STC is a double-acting tie-rod cylinder delivering 15708 N push force at 0.5 MPa (28274 N at 0.9 MPa), built for heavy short-stroke clamping and pressing tasks. Its 200 mm bore houses a 40 mm diameter piston rod with a 33 mm adjustable air cushion, and the 30 mm stroke keeps the extended body length compact at just 274 mm.
This model includes a built-in magnet (suffix S) for direct mounting of CMSG/DMSG/EMSG sensors, and ships with the TC centre trunnion mount plus TCM1 bracket (F-SC200TC) for pivoting actuation. Standard PT ports (PT3/4) and TPU seals suit normal -20 to +70 °C environments.

Where the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC200X30STC Is Used
Heavy Press Tool Actuation
Short 30 mm stroke with 28274 N force at 0.9 MPa for punch press stripper plates and die-cushion clamping.
Welding Fixture Clamping
Centre trunnion mount allows the cylinder to pivot, applying direct clamping force in robotic welding jigs.
Valve Actuator for Large Bore Pipes
Delivers high thrust in a short linear motion for opening and closing heavy industrial butterfly or gate valves.
Is the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC200X30STC the Right Cylinder?
With 15708 N push at 0.5 MPa, the SC200 suits heavy press and fixture applications. If your load requires less force, step down to the SC160 bore (10053 N at 0.5 MPa) for a lighter, more compact actuator. For higher force, the SC250 delivers 24544 N at the same pressure. Always match five points when replacing: bore (200 mm), stroke (30 mm), port thread (PT), mounting (TC centre trunnion), and magnet option (-S). For strokes over 300 mm on this bore, add an external guide to protect the 40 mm rod from bending under side load.
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 SC200X30STC FAQ
At 0.5 MPa, the push force is 15708 N and pull force is 15080 N. At the maximum operating pressure of 0.9 MPa, push force reaches 28274 N. The theoretical maximum at 1.0 MPa is 3204 kgf.
Yes, the -S suffix indicates a built-in magnet. You can directly clamp CMSG (reed) or DMSG/EMSG (solid-state) sensors onto the barrel for piston position feedback.
