About the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC200X900STC
The SC200X900STC is a large-bore double-acting pneumatic cylinder delivering 15708 N of push force at 0.5 MPa (28274 N at 0.9 MPa). With a 200 mm bore, 40 mm piston rod, and a 900 mm stroke, it is built for heavy industrial linear actuation where high force and moderate travel are required.
This model includes a built-in magnet (-S) for CMSG/DMSG/EMSG position sensors and a centre trunnion mount (TC) with TCM1 bracket, allowing the cylinder to pivot during operation. The 33 mm adjustable air cushion at each end decelerates the piston smoothly, protecting the end caps from impact at high cycle rates.

Where the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC200X900STC Is Used
Sawmill Log Positioning
Drives carriage stops and log turners with 15.7 kN of force at 0.5 MPa, handling heavy timber in dusty, wet sawmill environments.
Heavy-Duty Baler Compression
Powers the main compression ram in industrial balers for cardboard, plastic, or agricultural waste, cycling reliably under continuous high-load operation.
Steel Fabrication Clamping
Operates large welding jigs and fixture clamps, holding structural steel members with 28274 N of force at 0.9 MPa for precise assembly.
Is the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC200X900STC the Right Cylinder?
Select the SC200 when your application needs roughly 15.7 kN of push force at standard plant pressure. If you can work with about 10 kN, stepping down to the SC160 (10053 N at 0.5 MPa) reduces weight and air consumption. For strokes of 900 mm, always check side-load conditions: a 40 mm rod extending nearly a metre can bend under off-axis force. Use an external guide rail or a guided-cylinder assembly to protect the rod bearing and piston seals.
For a direct replacement, match five points: 200 mm bore, 900 mm stroke, PT port thread, centre trunnion (TC) mounting with F-SC200TC bracket, and the built-in magnet (-S) for barrel-mounted sensors. This is a tie-rod cylinder; it 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 SC200X900STC FAQ
At 0.5 MPa, the cylinder produces 15708 N pushing and 15080 N pulling. At the maximum operating pressure of 0.9 MPa, push force reaches 28274 N. The theoretical maximum at 1.0 MPa is 3204 kgf (31400 N push).
No. The 40 mm diameter piston rod extending 900 mm is susceptible to bending under side load. You must install an external linear guide or couple the rod to a guided tooling plate to prevent premature rod bearing wear and seal failure.
