About the Airtac SC50 Standard Cylinder SC50X450STC
The AirTAC SC50X450STC is a double-acting tie-rod cylinder delivering 982 N of push force at 0.5 MPa and up to 1767 N at the maximum operating pressure of 0.9 MPa. With a 50 mm bore, 20 mm piston rod, and a 450 mm stroke, it handles mid-range linear tasks where a centre trunnion pivot is required for the application's articulation.
This model includes a built-in magnet (-S) for direct mounting of CMSG/DMSG/EMSG sensors, plus the TC centre trunnion mount supplied with the TCM1 bracket (F-SC50TC). The adjustable air cushion (21 mm) decelerates the 20 mm rod smoothly at end-of-travel, while the PT1/4 ports and standard TPU seals keep it suited to general industrial air at -20 to +70 °C.

Where the Airtac SC50 Standard Cylinder SC50X450STC Is Used
Pivoting Conveyor Gate
The TC centre trunnion mount lets the cylinder body swing as it actuates a material diverter gate on a conveyor line, with the 450 mm stroke providing ample travel for wide chutes.
Clamp & Weld Fixture
Delivers 1767 N of clamping force at 0.9 MPa for holding parts in a welding jig. The built-in magnet confirms full extension via a CMSG sensor before the robot cycle starts.
Hopper Discharge Linkage
Operates a pivoting discharge door on a bulk material hopper. The trunnion mount absorbs the arcing motion, and the 450 mm stroke opens the door fully for clean flow cut-off.
Is the Airtac SC50 Standard Cylinder SC50X450STC the Right Cylinder?
Choose the SC50 bore when your load needs roughly 1000 N at 0.5 MPa; if the force is marginal, stepping up to the SC63 bore provides 1559 N at the same pressure. For lighter, more compact needs, the SC40 delivers 628 N. This 450 mm stroke is within the 1200 mm maximum standard stroke for the 50 mm bore.
At 450 mm of stroke, the 20 mm rod is extended significantly—avoid unguided side loads that can bend the rod or damage the bearing. Use an external linear guide or a guided cylinder for off-axis forces. For a direct replacement, match bore, stroke, PT port thread, centre trunnion mounting, and the integrated magnet; this configuration is specific to the AirTAC SC tie-rod series and 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 SC50 Standard Cylinder SC50X450STC FAQ
At 0.7 MPa supply pressure, the 50 mm bore generates 1374 N extending (push) and 825 N retracting (pull). The theoretical maximum at 1.0 MPa is 200 kgf, but the rated operating range is 0.15–1.0 MPa.
No. The AirTAC SC series is a tie-rod cylinder with a shorter body length (A=150 mm) than a comparable ISO 15552 cylinder, so mounting dimensions and overall length differ. It is a direct replacement only for another AirTAC SC50 tie-rod cylinder with matching stroke, PT ports, centre trunnion mount, and magnet.
