The AirTAC SC50 Standard Cylinder SC50X780S is a genuine double-acting standard air cylinder with a Ø50mm bore and 780mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The AirTAC SC50X780S is a double-acting tie-rod cylinder delivering 982 N of push force at 0.5 MPa (1767 N at 0.9 MPa). Its 20 mm diameter piston rod and 21 mm adjustable air cushion provide reliable deceleration for mid-range automation tasks.
With a 780 mm stroke and a built-in magnet, this model accepts CMSG/DMSG/EMSG sensors directly on the barrel for non-contact position sensing. The compact body length A of 150 mm keeps the overall extended length to 930 mm, fitting installations where space is limited but stroke length is critical.

The 780 mm stroke reaches across wide conveyors to stop or divert packages, with the magnetic piston enabling end-of-stroke confirmation via barrel-mounted sensors.
Moves components between distant fixtures or stations. The 982 N push force at 0.5 MPa handles medium-weight payloads, while the adjustable cushion protects tooling at the end of travel.
Operates a tall sorting gate or flap in logistics systems. The built-in magnet allows the control system to verify gate open/closed status without additional mechanical switches.
For higher force, step up to the 63 mm bore (1559 N at 0.5 MPa); for a lighter, faster actuator, the 40 mm bore offers 628 N. This 780 mm stroke is within the 1200 mm maximum standard stroke for bore 50. Long strokes with a 20 mm rod can experience bending under side load—consider an external guide rail or a guided cylinder if the load is not purely axial. When replacing, match bore (50 mm), stroke (780 mm), PT port thread, the built-in magnet (-S), and the basic mounting configuration to ensure direct compatibility with an existing AirTAC SC tie-rod cylinder.
Quick checklist
At 0.5 MPa the push force is 982 N and pull force is 825 N. At the maximum operating pressure of 0.9 MPa, push force reaches 1767 N. The theoretical maximum at 1.0 MPa is 200 kgf. Always factor in a safety margin for your application.
Yes. The -S suffix indicates a built-in magnet in the piston. You can clamp AirTAC CMSG (reed) or DMSG/EMSG (solid-state) sensors directly onto the barrel to detect piston position without any modification to the cylinder.
