About the Airtac SC50 Standard Cylinder SC50X370S
The SC50X370S is a double-acting pneumatic cylinder delivering 982 N of push force at 0.5 MPa (1767 N at 0.9 MPa). Its 20 mm diameter piston rod and 370 mm stroke suit medium-force linear positioning tasks where the stroke exceeds the common 300 mm standard increment.
This model includes a built-in magnet (-S suffix), allowing CMSG, DMSG, or EMSG reed and solid-state sensors to be mounted directly on the tie-rod barrel for reliable end-of-stroke detection. The adjustable air cushion at each end decelerates the piston smoothly, and the body length A is 150 mm, giving a total extended length of approximately 520 mm.

Where the Airtac SC50 Standard Cylinder SC50X370S Is Used
Conveyor Diverters
The 370 mm stroke and 982 N push force at 0.5 MPa reliably actuates medium-width conveyor diverter gates, with the built-in magnet confirming gate position via barrel-mounted sensors.
Part Clamping & Fixturing
Applies controlled clamping force for machining or assembly fixtures. The adjustable cushion protects the workpiece from impact shock at the end of the 370 mm advance.
Pallet Stop Mechanisms
Integrated into pallet conveyor lines, the SC50X370S stops and releases pallets. The magnetic piston enables simple sensor integration for automated warehouse control systems.
Is the Airtac SC50 Standard Cylinder SC50X370S the Right Cylinder?
Choose the SC50 for its 982 N push at 0.5 MPa; if you need more force, step up to the SC63 bore which provides 1559 N at the same pressure. For lighter, faster applications, the SC40 delivers 628 N. At 370 mm stroke, the 20 mm rod is well-supported, but avoid direct side loading—use an external linear guide if the load is not perfectly axial. For replacement, match the 50 mm bore, 370 mm stroke, PT port thread, and ensure the replacement also carries the -S magnet suffix 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 SC50X370S FAQ
At 0.5 MPa, 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 reaches 1767 N. The theoretical maximum at 1.0 MPa is 200 kgf.
Yes, the -S suffix indicates a built-in magnet. You can mount AirTAC CMSG (reed) or DMSG/EMSG (solid-state) sensors directly onto the cylinder's tie-rod barrel to detect piston position without external brackets.
