The AirTAC SC50 Standard Cylinder SC50X660S is a genuine double-acting standard air cylinder with a Ø50mm bore and 660mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The SC50X660S is a double-acting pneumatic cylinder delivering 982 N of push force when operated at 0.5 MPa, scaling to 1767 N at the maximum operating pressure of 0.9 MPa. Its 50 mm bore houses a 20 mm diameter piston rod with an M16x1.5 male thread, and the 660 mm stroke is well within the 1200 mm maximum standard stroke for this bore size.
This model includes the -S suffix, meaning a built-in magnet is fitted as standard. This allows easy, non-invasive mounting of CMSG, DMSG, or EMSG reed and solid-state sensors directly onto the tie-rod barrel for precise, reliable end-of-stroke or mid-stroke position feedback without additional brackets.

The 660 mm stroke and 982 N push force at 0.5 MPa effectively actuates diverter gates on wide conveyor lines, reliably sorting packages or bulk materials with sensor-confirmed positioning via the built-in magnet.
Clamps and positions large sheet metal parts in welding cells. The 20 mm rod provides rigidity over the long stroke, while magnetic sensors verify clamp engagement to ensure robotic welding safety.
Pushes a stack of empty pallets forward in a dispenser. The SC50X660S provides the necessary reach and force, and the -S magnet option enables cycle counting and jam detection via barrel-mounted sensors.
For applications requiring slightly less force, stepping down to a 40 mm bore provides 628 N of push force at 0.5 MPa in a more compact body. If your load demands higher thrust, the 63 mm bore delivers 1559 N at the same pressure. With a 660 mm stroke, ensure the rod is protected from significant side loads; for long-stroke applications where the load is not perfectly guided, consider pairing this cylinder with an external linear guide or switching to a guided cylinder to prevent rod bending and premature seal wear.
To guarantee a direct replacement, match five key specifications: the 50 mm bore, the 660 mm stroke, the PT port thread, the basic mounting style, and the built-in magnet (-S) for sensor compatibility.
Quick checklist
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.
Yes. The -S suffix in the model code SC50X660S indicates a built-in magnet is installed. This allows you to clamp compatible AirTAC CMSG, DMSG, or EMSG sensors directly onto the cylinder's tie-rod barrel to detect piston position without any additional mounting hardware.
