The AirTAC SC50 Standard Cylinder SC50X790S is a genuine double-acting standard air cylinder with a Ø50mm bore and 790mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The SC50X790S is a double-acting pneumatic cylinder delivering 982 N of push force at 0.5 MPa and up to 1767 N at the maximum operating pressure of 0.9 MPa. Its 50 mm bore, 20 mm diameter piston rod, and 790 mm stroke make it suitable for medium-force linear tasks requiring a long reach, such as material transfer or pressing operations.
This model includes a factory-installed -S magnet, allowing CMSG, DMSG, or EMSG reed and solid-state sensors to be mounted directly on the tie-rod barrel for precise, non-contact position sensing. With a body length of 150 mm, the total extended length is approximately 940 mm. The adjustable pneumatic cushion at each end decelerates the piston smoothly, reducing end-of-stroke impact.

The 790 mm stroke pushes or pulls components between distant conveyor lines or workstations, with the built-in magnet confirming end-of-travel via barrel-mounted sensors.
Applies up to 1767 N of clamping force at 0.9 MPa for gluing, welding, or assembly fixtures, with sensor feedback ensuring the clamp is fully engaged before the cycle proceeds.
Actuates a diverter gate or flipper in a sorting system. The long stroke provides the necessary travel, while the magnetic piston allows position verification at both ends of the cycle.
Select the SC50 when your application needs around 982 N of force at standard plant pressure. For a step down in force, the 40 mm bore SC40 series provides 628 N at 0.5 MPa; for higher force, the 63 mm bore SC63 series delivers 1559 N. This 790 mm stroke is within the 1200 mm maximum standard stroke for the 50 mm bore.
For this long 790 mm stroke, carefully evaluate side loads. An unsupported 20 mm rod extending nearly 800 mm is susceptible to bending under lateral force. Use an external guide rail or a guided cylinder assembly to protect the rod and bearing from premature wear. When replacing, match five points: 50 mm bore, 790 mm stroke, PT port thread, the -S magnet for sensor compatibility, and the basic mounting configuration.
Quick checklist
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 force at 1.0 MPa is 200 kgf.
Yes, the -S suffix in the model code SC50X790S indicates a built-in magnet in the piston. 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 brackets.
