About the Airtac SC50 Standard Cylinder SC50X375SN
The SC50X375SN is a double-acting pneumatic cylinder delivering 982 N of push force at 0.5 MPa and 1767 N at the maximum operating pressure of 0.9 MPa. With a 50 mm bore and 375 mm stroke, this tie-rod actuator uses a 20 mm diameter piston rod with M16x1.5 male threads and PT1/4 ports.
This model includes a built-in magnet (-S suffix) so CMSG, DMSG, or EMSG reed and solid-state sensors can be clamped directly onto the barrel for contactless position sensing. The -N suffix specifies NBR (nitrile) seals, making it suitable for standard industrial air service within the -20 to +70 °C temperature range.

Where the Airtac SC50 Standard Cylinder SC50X375SN Is Used
Material Sorting Gates
The 375 mm stroke and built-in magnet allow precise end-of-stroke sensing for diverting packages or parts on conveyor lines, with 1374 N of push force at 0.7 MPa to move medium-weight gates.
Clamping & Fixturing
Delivers 1767 N of clamping force at 0.9 MPa. The NBR seals and magnetic piston enable sensor-confirmed clamp/unclamp cycles in machining and assembly fixtures.
Lift & Transfer Mechanisms
Used in vertical lift assists or horizontal transfer shuttles, the 20 mm rod and 50 mm bore provide a balanced push/pull force (982 N / 825 N at 0.5 MPa) for handling totes and components.
Is the Airtac SC50 Standard Cylinder SC50X375SN the Right Cylinder?
For applications needing slightly less force, the 40 mm bore SC40 series provides 879 N at 0.7 MPa, while stepping up to the 63 mm bore SC63 series offers 2182 N at the same pressure. At 375 mm stroke, the rod is well-supported within the 1200 mm maximum standard stroke for this bore, but always avoid direct side loading on the rod; use an external linear guide if the load is not perfectly axial.
To replace an existing cylinder, match five points: 50 mm bore, 375 mm stroke, PT1/4 port thread, the built-in magnet (-S) for sensor compatibility, and NBR seal material. The SC series is a tie-rod cylinder and is dimensionally shorter than an ISO 15552 profile cylinder, so it is not a direct ISO replacement.
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 SC50X375SN FAQ
At 0.7 MPa (7 bar), the theoretical push force is 1374 N and the pull force on the retract stroke is 825 N, based on the 50 mm bore and 20 mm rod diameter.
No. The AirTAC SC series is a tie-rod cylinder with a shorter overall body length than an ISO 15552 profile cylinder. It will only directly replace another AirTAC SC tie-rod cylinder or a compatible tie-rod design with matching bore, stroke, PT ports, magnet, and NBR seals.
