The AirTAC SC50 Standard Cylinder SC50X920S is a genuine double-acting standard air cylinder with a Ø50mm bore and 920mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The AirTAC SC50X920S is a double-acting tie-rod cylinder with a 50 mm bore and a 920 mm stroke, delivering a push force of 982 N at 0.5 MPa and up to 1767 N at the maximum operating pressure of 0.9 MPa. Its 20 mm diameter piston rod and 21 mm adjustable air cushion provide reliable end-of-stroke deceleration for mid-range linear motion tasks.
This model includes a built-in magnet (-S suffix), allowing direct mounting of CMSG, DMSG, or EMSG reed and solid-state sensors on the barrel for non-contact position sensing. With a body length A of 150 mm, the total extended length reaches 1070 mm, making it suitable for applications requiring a long reach from a compact body.

The 920 mm stroke moves components between distant conveyor stations or assembly nests, with the built-in magnet enabling end-of-stroke confirmation via barrel-mounted sensors.
Operates tall hopper gates or chute diverters in material handling systems, using the 982 N push force at standard plant air pressure to lift or slide bulk flow control plates.
Extends a dispensing head across a wide panel or workpiece. The adjustable cushion prevents fluid splatter at stroke end, and the magnet confirms full retraction before the next cycle.
Select the SC50X920S when the 50 mm bore's force profile matches your load; at 0.5 MPa it provides 982 N push and 825 N pull. If you need more force, step up to the 63 mm bore (SC63 series) which offers 1559 N push at the same pressure. For lighter, faster applications, the 40 mm bore provides 628 N push.
This cylinder has a 920 mm stroke, which is long relative to the 20 mm rod diameter. To prevent rod buckling or bearing wear under side loads, always guide the load externally with rails or rods, or consider a guided cylinder. For direct replacement, match these five attributes: 50 mm bore, 920 mm stroke, PT port thread, basic mounting (no bracket), and the -S magnet option for sensor compatibility.
Quick checklist
At 0.7 MPa operating pressure, the SC50X920S produces a theoretical push force of 1374 N and a pull force of 1155 N (calculated from the 825 N pull at 0.5 MPa). The maximum push force at 0.9 MPa is 1767 N.
Yes. The -S suffix in SC50X920S indicates a built-in magnet in the piston. This allows AirTAC CMSG (reed) or DMSG/EMSG (solid-state) sensors to be clamped directly onto the cylinder barrel's sensor groove for precise, non-contact position feedback.
