About the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC200X800STC
The AirTAC SC200X800STC is a double-acting tie-rod cylinder delivering 15708 N of push force at 0.5 MPa, scaling up to 28274 N at the maximum operating pressure of 0.9 MPa. With an 800 mm stroke and a robust 40 mm diameter piston rod, this model is built for heavy linear work where substantial force is required over a long travel distance.
This specific configuration includes a built-in magnet (-S) for direct mounting of CMSG/DMSG/EMSG sensors and a centre trunnion (TC) mount, supplied with the TCM1 bracket (F-SC200TC). The total extended body length is approximately 1044 mm, with a 33 mm adjustable air cushion at each end to decelerate high inertial loads smoothly.

Where the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC200X800STC Is Used
Sawmill Log Handling
Pivots large log cradles or gates in sawmill operations, using the TC trunnion mount for smooth swinging motion and the 800 mm stroke for full material transfer.
Heavy Agricultural Implement Control
Actuates depth-control mechanisms or large chute diverters on heavy farm machinery, where the 200 mm bore force and trunnion pivot are ideal for high-resistance, arcing movements.
Mining Conveyor Diverter Gates
Operates heavy diverter gates on mining aggregate conveyors, leveraging the 28274 N max force to shift dense material flows and the magnet for end-of-travel position sensing.
Is the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC200X800STC the Right Cylinder?
Select the SC200X800STC when your application demands the 15708 N push force at 0.5 MPa of a 200 mm bore. If your force requirement is lower, the 125 mm bore provides 6136 N, potentially reducing air consumption. For even higher forces, the 250 mm bore offers 24544 N. For this 800 mm stroke, ensure the rod is protected from side loading; an external guide or a guided cylinder is recommended to prevent rod bending and premature bearing wear. To match this cylinder for replacement, verify five points: 200 mm bore, 800 mm stroke, PT port thread, centre trunnion (TC) mount with TCM1 bracket, and the built-in magnet (-S) for sensor compatibility.
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 SC200X800STC FAQ
At 0.5 MPa, the push force is 15708 N and the pull force is 15080 N. 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.
No. The SC200X800STC is a double-acting cylinder and will not hold its position if air pressure is lost or the directional valve is centered. The piston will drift or drop under load. For load holding, you must add an external rod brake, a mechanical lock, or a pilot-operated check valve.
