The AirTAC SC50 Standard Cylinder SC50X770 is a genuine double-acting standard air cylinder with a Ø50mm bore and 770mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The AirTAC SC50X770 is a double-acting single-rod pneumatic cylinder with a 50 mm bore and a 770 mm stroke. This non-standard stroke length exceeds the standard maximum of 1200 mm for the 50 mm bore, making it a made-to-order unit for applications needing a precise extended reach. At 0.5 MPa, it provides a push force of 982 N and a pull force of 825 N, scaling up to 1767 N of thrust at the maximum operating pressure of 0.9 MPa.
This cylinder features a 20 mm diameter piston rod with an M16x1.5 male thread and a PT1/4 port for air supply. The total extended body length is approximately 920 mm, calculated from the 150 mm body length A plus the 770 mm stroke. It uses an adjustable pneumatic cushion (21 mm length) to decelerate the piston near the end of its travel, reducing impact noise and vibration. The standard TPU seals provide an operating temperature range of -20 to +70 °C.

The 770 mm stroke moves components across wide gaps in packaging lines, transferring products between distant conveyor belts with a controlled 982 N push force.
Used to push heavy sheets or panels out of a staging area. The 1767 N maximum force at 0.9 MPa handles dense materials, while the adjustable cushion ensures a soft stop.
Actuates a large diverter gate in gravity-fed chutes. The double-acting air control provides positive retraction and extension for reliable sorting of bulk items.
For a 50 mm bore, the SC50X770 offers a middle-ground force class. If your load requires more force, stepping up to the SC63 bore increases push force to 1559 N at 0.5 MPa. For lighter, more compact applications, the SC40 bore provides 628 N. Because the 770 mm stroke is long relative to the 20 mm rod diameter, the unsupported rod is susceptible to bending under side loads; an external linear guide or a guided cylinder is strongly recommended to protect the rod bearing and seals from premature wear.
To ensure a correct direct replacement, match five key specifications: the bore (50 mm), the stroke (770 mm), the port thread type (PT), the mounting style (basic, no bracket), and the magnet option (none). This model uses the standard PT thread; a G-thread variant would require a different suffix code. Always verify the non-standard stroke length against your existing equipment.
Quick checklist
At the standard 0.5 MPa operating pressure, the cylinder delivers 982 N of push force and 825 N of pull force. At the maximum operating pressure of 0.9 MPa, the push force increases to 1767 N.
No, the maximum standard stroke for a 50 mm bore SC cylinder is 1200 mm. While 770 mm is within that limit, it is not one of the preferred standard stroke increments (like 750 or 800 mm) and is typically treated as a non-standard, made-to-order length. Always confirm lead time with your supplier.
