About the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC250X500TC
The AirTAC SC250X500TC is a double-acting pneumatic cylinder engineered for heavy-duty linear force applications, delivering a substantial 24544 N of push force at 0.5 MPa and up to 44178 N at the maximum operating pressure of 0.9 MPa. With a 500 mm stroke and a robust 50 mm diameter piston rod, this model is built for demanding industrial tasks requiring high thrust and structural rigidity.
This configuration includes the TC centre trunnion mount, supplied with the TCM1 bracket (F-SC250TC), allowing the cylinder to pivot during operation to accommodate angular movement of the load. The body length A is 294 mm, and the total extended length is approximately 794 mm. It operates on filtered air within a standard temperature range of -20 to +70 °C using TPU seals and PT ports.

Where the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC250X500TC Is Used
Sawmill Log Handling
Provides the high force needed for positioning and clamping large logs on carriages and conveyors, with the trunnion mount absorbing the pivot action.
Heavy Agricultural Implements
Controls the lift and angle of large tillage tools or harvesting headers on tractors, where high thrust and a pivoting mount are essential.
Scrap Baler Compaction
Drives the main compaction ram in recycling balers, generating up to 44178 N of force to densely pack scrap material into bales.
Is the Airtac SC200-250 Tie-Rod Cylinder Aluminum Alloy SC250X500TC the Right Cylinder?
Select the SC250X500TC when your application requires a force output in the 24.5 kN class at standard plant pressure. If your force requirement is slightly lower, the SC200 bore provides 15708 N of push force at 0.5 MPa, which may offer a more compact and cost-effective solution. For strokes of 300 mm or greater, always assess the potential for side loading on the piston rod. At a 500 mm extension, an external guide rail or a guided cylinder configuration is strongly recommended to protect the rod bearing from bending moments and ensure long service life. For direct replacement, match the 250 mm bore, 500 mm stroke, PT port thread, centre trunnion (TC) mounting, and the absence of a magnet sensor option.

- ✓ 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 SC250X500TC FAQ
At 0.7 MPa (7 bar) operating pressure, the SC250 bore cylinder produces a theoretical push force of 34361 N. The pull force on the retract stroke is 23562 N, accounting for the volume of the 50 mm piston rod.
The TC centre trunnion allows the cylinder body to pivot around its midpoint, which is critical for applications where the load travels in an arc. The mounting kit F-SC250TC includes the trunnion block and the TCM1 bracket, and must be securely fixed to a machine frame that can handle the full thrust reaction forces.
