The AirTAC SC50 Standard Cylinder SC50X860S is a genuine double-acting standard air cylinder with a Ø50mm bore and 860mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The AirTAC SC50X860S is a double-acting single-rod 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 an 860 mm stroke and a 20 mm diameter piston rod, it is built for linear applications requiring a moderate force output over a long travel distance.
This model includes a built-in magnet (-S suffix), allowing direct mounting of CMSG, DMSG, or EMSG reed and solid-state sensors on the tie-rod barrel for precise end-of-stroke or mid-stroke position feedback. The standard TPU seals provide reliable operation in ambient temperatures from -20 to +70 °C, and the PT1/4 ports ensure straightforward pneumatic connections.

Pushing or pulling product carriers along an 860 mm path on a packaging or assembly conveyor line, with sensors confirming full extension and retraction.
Indexing a large panel or door through a multi-stage process, using the cylinder's long stroke and magnetic piston for position verification at each step.
Actuating a diverter gate in a gravity chute or sorting system, where the 982 N force at 0.5 MPa is sufficient to move the gate and the sensors confirm position.
For applications needing slightly more force, stepping up to the 63 mm bore provides a push force of 1559 N at 0.5 MPa. If a lighter, more compact cylinder is preferred, the 40 mm bore offers 628 N. At an 860 mm stroke, the 20 mm rod is well-supported within the cylinder, but if significant side loads are present in the application, consider adding an external linear guide or switching to a guided cylinder to prevent rod bending and premature bearing wear. When replacing an existing unit, match the 50 mm bore, 860 mm stroke, PT1/4 port thread, and ensure the replacement has the -S magnet option for sensor compatibility.
Quick checklist
The theoretical push force is 982 N at 0.5 MPa and 1767 N at 0.9 MPa (max operating pressure). The pull force on the retract stroke is 825 N at 0.5 MPa due to the area of the 20 mm rod. The maximum theoretical force at 1.0 MPa is 200 kgf.
Yes. The -S suffix indicates a built-in magnet in the piston, making it compatible with AirTAC CMSG (reed) and DMSG/EMSG (solid-state) sensors that clamp directly onto the cylinder's tie-rod barrel for non-contact position sensing.
