About the Airtac SC50 Standard Cylinder SC50X381S
The AirTAC SC50X381S is a double-acting pneumatic cylinder delivering 982 N of push force and 825 N of pull force when operated at 0.5 MPa. Its 20 mm diameter piston rod and 150 mm body length provide a solid foundation for linear motion tasks requiring a 381 mm stroke.
This model includes a built-in magnet, allowing easy mounting of CMSG, DMSG, or EMSG sensors directly on the barrel for precise position feedback. The adjustable air cushion at each end decelerates the piston smoothly, reducing impact noise and vibration. Operating pressure ranges from 0.15 to 1.0 MPa with standard PT1/4 ports.

Where the Airtac SC50 Standard Cylinder SC50X381S Is Used
Material Handling
Operates pushers and stops on packaging lines, using the 381 mm stroke to transfer cartons between conveyor sections with sensor-confirmed positioning.
Clamping & Fixturing
Provides consistent 982 N clamping force in woodworking or metalworking jigs, with the magnetic sensor verifying the clamp is fully engaged.
Agricultural Machinery
Activates gates or diverters on seed and grain handling equipment, where the long stroke and sensor feedback ensure complete open/close cycles.
Is the Airtac SC50 Standard Cylinder SC50X381S the Right Cylinder?
For applications needing slightly more force, consider stepping up to the SC63 series, which offers 1559 N of push at the same 0.5 MPa pressure. If a shorter, more compact cylinder is acceptable, the SC50X250 provides a 250 mm stroke within the same bore family. When replacing this cylinder, match five key points: 50 mm bore, 381 mm stroke, PT1/4 port thread, the built-in magnet (-S suffix), and your required mounting accessories. For strokes over 300 mm, ensure the rod is externally guided if side loads are present to prevent bending.
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 SC50X381S FAQ
At 0.5 MPa (5 bar), it produces 982 N extending and 825 N retracting. At the maximum operating pressure of 0.9 MPa, the extending force increases to 1767 N.
Yes, the -S suffix indicates a built-in magnet. You can directly attach AirTAC CMSG, DMSG, or EMSG sensors to the barrel to detect piston position without additional brackets.
