About the Airtac SC50 Standard Cylinder SC50X115TC
The SC50X115TC is a 50 mm bore double-acting pneumatic cylinder with a 115 mm stroke, factory-configured with a centre trunnion mount for pivoting applications. At 0.5 MPa it generates 982 N of push force and 825 N on the pull stroke, stepping up to 1767 N at the maximum operating pressure of 0.9 MPa.
This model uses a 20 mm diameter piston rod with M16x1.5 male threads and PT1/4 ports. The tie-rod construction keeps the body length to a compact 150 mm (A dimension), giving a total extended length of approximately 265 mm. TPU seals provide a standard operating range of -20 to +70 °C, and the 21 mm adjustable air cushion at each end decelerates the piston smoothly.

Where the Airtac SC50 Standard Cylinder SC50X115TC Is Used
Conveyor Diverter Gates
The centre trunnion mount lets the cylinder pivot as it actuates a flipper gate or diverter arm on a packaging line, handling 1767 N of push force at full pressure without binding.
Clamp & Weld Fixtures
Delivers 825 N of pull force at 0.5 MPa to lock a toggle clamp on an automotive welding jig. The trunnion allows the cylinder to swing clear for part loading.
Hopper & Chute Actuation
Operates a discharge gate on a seed or grain hopper. The pivoting TC mount accommodates the arc of the gate linkage, while TPU seals handle dusty, ambient-temperature environments.
Is the Airtac SC50 Standard Cylinder SC50X115TC the Right Cylinder?
Choose the SC50 bore when your application needs between 982 N and 1767 N of push force. If you need more force, the SC63 delivers 1559 N at 0.5 MPa; for a lighter, more compact solution the SC40 provides 628 N. The 115 mm stroke is well within the 1200 mm maximum standard stroke for this bore.
For a direct replacement, match five points: 50 mm bore, 115 mm stroke, PT1/4 port thread, centre trunnion (TC) mounting, and the absence of a magnet. The TC mount ships with the TCM1 trunnion bracket (accessory code F-SC50TC) and allows the cylinder body to pivot, which is essential for following an arc without binding. If side loads are present even with the trunnion, add an external guide or rod support.
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 SC50X115TC FAQ
At 0.7 MPa the push force is 1374 N, and the pull force is 1155 N. The maximum push force at the 0.9 MPa operating limit is 1767 N. These values assume a static piston; dynamic force is typically 70-80% of static.
No. The SC series is a tie-rod cylinder that is shorter than an ISO 15552 cylinder, so the mounting dimensions and overall length will not match. Replace it with another AirTAC SC50X115TC, or match the same SC50 bore, stroke, PT port, and TC trunnion configuration to ensure the pivot centre and port positions align.
