About the Airtac SC50 Standard Cylinder SC50X380N
The AirTAC SC50X380N is a double-acting tie-rod cylinder with a 50 mm bore and 380 mm stroke, fitted with NBR (nitrile) seals for general industrial air service. At 0.5 MPa it produces 982 N pushing force and 825 N pulling force, rising to 1767 N push at the maximum operating pressure of 0.9 MPa.
This model uses a 20 mm diameter piston rod with an M16x1.5 male thread and PT1/4 ports. The adjustable air cushion at each end is 21 mm long, and the body length A is 150 mm, giving a total extended length of approximately 530 mm. The standard operating temperature range for the NBR seal is -20 to +70 °C.

Where the Airtac SC50 Standard Cylinder SC50X380N Is Used
Part Transfer & Sorting
The 380 mm stroke and 982 N push force at 0.5 MPa move components between conveyor lanes or into inspection nests reliably in automated lines.
Light Assembly Pressing
Delivers up to 1767 N at 0.9 MPa for pressing bushings, bearings, or clips into housings on benchtop assembly fixtures.
Material Gate Actuation
Operates diverters or gates on chutes and hoppers handling granular materials, where the NBR seals provide good wear resistance in dry, non-aggressive environments.
Is the Airtac SC50 Standard Cylinder SC50X380N the Right Cylinder?
Choose the SC50X380N where a mid-range 50 mm bore provides enough force for clamping, pressing, or lifting tasks up to about 1767 N at 0.9 MPa. If your load requires more force, step up to the SC63 bore which delivers 1559 N push at 0.5 MPa; for a lighter, faster-moving application the SC40 bore offers 628 N at 0.5 MPa.
At 380 mm stroke, the unsupported rod is long enough that side loads or off-centre mounting can cause rod bending and premature bearing wear. Fit an external linear guide or consider a guided cylinder if the load is not perfectly axial. For direct replacement, match five points: 50 mm bore, 380 mm stroke, PT1/4 ports, NBR seal material, and basic (no bracket) mounting. The SC50 is a tie-rod design 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 SC50X380N FAQ
At 0.7 MPa (7 bar) the SC50X380N produces a theoretical pushing force of 1374 N. The pulling force at the same pressure is 1155 N (calculated from the 825 N pull at 0.5 MPa). Actual force is slightly lower due to friction.
No. The AirTAC SC series is a tie-rod cylinder with a shorter body length than an ISO 15552 cylinder of the same bore and stroke. The mounting dimensions, port locations, and overall envelope differ. Only replace another AirTAC SC50 tie-rod cylinder with the same stroke, port thread, and mounting configuration.
