The AirTAC SC50 Standard Cylinder SC50X78 is a genuine double-acting standard air cylinder with a Ø50mm bore and 78mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The SC50X78 is a non-standard stroke variant in the AirTAC SC tie-rod cylinder family, built with a 50 mm bore and a 78 mm stroke. At 0.5 MPa operating pressure, this double-acting cylinder generates 982 N of push force and 825 N on the pull stroke, driven by a 20 mm diameter piston rod with M16x1.5 male threads.
With a compact body length A of 150 mm, the total extended length reaches 228 mm. It features PT1/4 pneumatic ports and an adjustable air cushion of 21 mm at each end to decelerate the piston smoothly. The standard TPU seals provide an operating range of -20 to +70 °C.

Quickly diverts small to medium packages on a conveyor line. The 78 mm stroke provides a crisp, short-throw actuation ideal for high-cycle diverting gates.
Applies 982 N of clamping force at standard shop air pressure. The compact 228 mm extended length fits neatly into CNC machine tool fixtures for workholding.
Delivers controlled linear force for inserting pins or bushings. The adjustable cushion prevents impact damage to delicate assembly components at the end of the 78 mm stroke.
For applications needing slightly more force, stepping up to the 63 mm bore SC63 series provides 1559 N of push force at the same 0.5 MPa pressure. If a shorter, more compact body is required, the 40 mm bore SC40 delivers 628 N. This 78 mm stroke is non-standard, so verify lead time. When replacing, match five key points: 50 mm bore, 78 mm stroke, PT port thread, basic mounting (no brackets), and the absence of a magnet. For strokes over 300 mm, consider an external guide to protect the rod from side-load bending, though at 78 mm this is not a primary concern.
Quick checklist
At the standard operating pressure of 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 increases to 1767 N.
No. The AirTAC SC series is a tie-rod cylinder that is shorter in overall length than an ISO 15552 profile cylinder of the same bore and stroke. It is not dimensionally interchangeable with ISO 15552 mounts. For replacement, match another SC tie-rod cylinder with a 50 mm bore and 78 mm stroke.
