The AirTAC SC50 Standard Cylinder SC50X780 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 SC50X780 is a double-acting tie-rod cylinder engineered for linear applications requiring a long, non-standard 780 mm stroke from a 50 mm bore. At the standard operating pressure of 0.7 MPa, this model generates a push force of 1374 N, making it suitable for medium-duty transfer and positioning tasks.
This cylinder features a 20 mm diameter piston rod with an M16x1.5 male thread and PT1/4 port connections. The body length A is 150 mm, resulting in a total extended length of approximately 930 mm. With an adjustable air cushion of 21 mm at each end, it effectively decelerates the piston to reduce end-of-stroke impact noise and vibration.

Moves components between distant stations on an assembly line, utilizing the 780 mm stroke to bridge wide gaps without complex multi-stage actuators.
Provides the extended, consistent linear motion needed to apply adhesives or sealants along a lengthy workpiece, with adjustable cushioning for smooth stops.
Ejects tall stacks of products or pushes heavy bins off a conveyor spur, leveraging the 1767 N force at 0.9 MPa for reliable material handling.
For applications requiring more force, stepping up to a 63 mm bore (SC63 series) provides 2182 N of push force at 0.7 MPa. If a shorter, standard stroke is acceptable, the SC50 offers standard strokes up to 500 mm, which may reduce lead time compared to this non-standard 780 mm stroke. When replacing an existing cylinder, ensure a 5-point match: 50 mm bore, 780 mm stroke, PT1/4 port thread, basic mounting (no brackets), and the absence of a magnetic piston.
At this extended stroke length, the 20 mm rod is susceptible to bending under side loads. It is strongly recommended to use an external linear guide or rod support to prevent rod bearing damage and ensure consistent, reliable operation throughout the full travel.
Quick checklist
The theoretical push force at 0.5 MPa is 982 N, at 0.7 MPa is 1374 N, and at the maximum operating pressure of 0.9 MPa is 1767 N. The pull force on the retract stroke is lower due to the 20 mm rod area, delivering 825 N at 0.5 MPa.
No, 780 mm is a non-standard stroke for the 50 mm bore, as the maximum standard stroke is 1200 mm. To prevent rod buckling or bearing damage on such a long stroke, always guide the load externally and avoid applying direct side loads to the rod end.
