About the Airtac SC50 Standard Cylinder SC50X320STC
The AirTAC SC50X320STC is a tie-rod double-acting cylinder delivering 982 N of push force at 0.5 MPa and up to 1767 N at the 0.9 MPa maximum operating pressure. With a 50 mm bore, 20 mm piston rod, and a 320 mm stroke, it suits medium-force linear tasks where the stroke length exceeds common short-stroke modules.
This model includes a built-in magnet (-S suffix) for direct mounting of CMSG/DMSG/EMSG reed or solid-state sensors, and a centre trunnion mount (TC suffix, supplied with TCM1 bracket) for pivoting actuation. The body length A is 150 mm, giving an approximate extended length of 470 mm. Standard PT ports (PT1/4) and TPU seals with a -20 to +70 °C operating range complete the configuration.

Where the Airtac SC50 Standard Cylinder SC50X320STC Is Used
Conveyor Diverter Gates
The 320 mm stroke and centre trunnion mount allow the cylinder to pivot smoothly, making it ideal for actuating diverter gates on medium-duty packaging or sorting conveyors.
Clamping & Fixturing
With 1767 N of clamping force at 0.9 MPa and magnetic sensor feedback, this cylinder provides reliable part holding in CNC welding jigs and assembly fixtures.
Agricultural Machinery Linkages
The robust tie-rod design and trunnion pivot suit the dusty, variable-load conditions of agricultural equipment like baler door actuators or chute controls.
Is the Airtac SC50 Standard Cylinder SC50X320STC the Right Cylinder?
Choose the SC50 bore when your application needs around 982 N push at 0.5 MPa. If you require 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 offers 628 N. This 320 mm stroke is within the 1200 mm maximum standard stroke for bore 50.
For strokes of 300 mm or more, be cautious of side loads—an unsupported 20 mm rod at full extension can bend under off-axis force. Use an external guide rail or switch to a guided cylinder if the load is not perfectly axial. When replacing an existing unit, match these five points exactly: 50 mm bore, 320 mm stroke, PT1/4 port thread, centre trunnion (TC) mounting with TCM1 bracket, and the built-in magnet 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 SC50 Standard Cylinder SC50X320STC 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 force at 1.0 MPa is 200 kgf.
No. The AirTAC SC series is a tie-rod cylinder and is physically shorter than an ISO 15552 profile cylinder, so it is not dimensionally interchangeable. It is a direct replacement only for another AirTAC SC tie-rod cylinder with matching bore, stroke, PT port, TC centre trunnion mount, and -S magnet option.
