About the Airtac SC50 Standard Cylinder SC50X265TC
The AirTAC SC50X265TC is a double-acting tie-rod cylinder with a 50 mm bore and a non-standard 265 mm stroke, factory-supplied with a centre trunnion (TC) mount for pivoting applications. At 0.5 MPa it generates 982 N of push force and 825 N of pull force, while at the maximum operating pressure of 0.9 MPa the push force reaches 1767 N.
This model uses a 20 mm diameter piston rod with M16x1.5 male threads and PT1/4 port connections. The adjustable air cushion at each end provides a 21 mm deceleration zone, and the total extended body length is approximately 415 mm. The TC mount includes the TCM1 trunnion bracket (part code F-SC50TC), allowing the cylinder to swing freely in a clevis or bracket arrangement.

Where the Airtac SC50 Standard Cylinder SC50X265TC Is Used
Conveyor Diverter Gates
The 265 mm stroke and centre trunnion mount let the SC50X265TC pivot a diverter gate or flipper on a packaging or sorting conveyor, using its 982 N push force at 0.5 MPa to redirect products reliably.
Clamping & Welding Fixtures
With the TC trunnion allowing angular movement, this cylinder suits pneumatic clamping arms on welding jigs. The 1767 N force at 0.9 MPa provides strong, repeatable hold-down pressure for metal fabrication.
Agricultural Implement Actuation
The pivoting TC mount and 265 mm stroke work well for actuating chutes, hopper doors, or sprayer boom folds on farm machinery, where the cylinder needs to swing through an arc during operation.
Is the Airtac SC50 Standard Cylinder SC50X265TC the Right Cylinder?
Choose the SC50 bore when your application needs roughly 982 N of push force at 0.5 MPa. If the load requires more force, step up to the SC63 bore which provides 1559 N at the same pressure; for a lighter, more compact solution, the SC40 bore delivers 628 N. Because this is a 265 mm stroke on a 20 mm rod, avoid unsupported side loads—the rod can bend under off-axis forces, so use an external linear guide or a guided cylinder if lateral loads are present.
For a direct replacement, match five attributes: 50 mm bore, 265 mm stroke, PT1/4 port thread, centre trunnion (TC) mounting with the F-SC50TC bracket, and no built-in magnet. This ensures the mounting geometry, port size, and pivot point align with your existing setup.
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 SC50 Standard Cylinder SC50X265TC FAQ
At the standard 0.5 MPa operating pressure, the push force is 982 N and the pull force is 825 N. At the maximum operating pressure of 0.9 MPa, the push force increases to 1767 N. The theoretical maximum at 1.0 MPa is 200 kgf.
Yes, provided your existing cylinder is an AirTAC SC50 with a 265 mm stroke, PT1/4 ports, and the centre trunnion (TC) mount. Confirm the F-SC50TC trunnion bracket position matches your pivot point, and note that this model does not include a built-in magnet for sensors.
