The AirTAC SC50 Standard Cylinder SC50X340 is a genuine double-acting standard air cylinder with a Ø50mm bore and 340mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The AirTAC SC50X340 is a double-acting single-rod pneumatic cylinder delivering 982 N of push force at 0.5 MPa (1374 N at 0.7 MPa). Its 340 mm stroke is well within the 1200 mm maximum standard stroke for the 50 mm bore, making it a standard-configuration actuator for medium-reach linear tasks.
Built on a proven tie-rod design with a 20 mm diameter piston rod and M16x1.5 rod thread, this cylinder includes an adjustable air cushion (21 mm cushion length) to decelerate the piston smoothly at end-of-stroke. The body length A is 150 mm, giving a total extended length of approximately 490 mm. Ports are PT1/4, and the standard TPU seals suit operating temperatures from -20 to +70 °C.

Actuates a diverter arm on a conveyor line. The 340 mm stroke provides ample reach to push medium-weight packages onto a branching lane, with the adjustable cushion ensuring quiet, low-impact operation at high cycle rates.
Applies 982 N of clamping force at 0.5 MPa to hold workpieces during machining or assembly. The tie-rod construction offers rigidity, while the 20 mm rod resists deflection under direct axial load.
Controls the angle of a discharge chute on a seed or grain handling system. The 340 mm stroke adjusts the flow direction precisely, and the TPU seals handle dusty agricultural environments within the standard temperature range.
For applications needing slightly less force, consider stepping down to the 40 mm bore (628 N at 0.5 MPa). If your load requires more push, the 63 mm bore provides 1559 N at the same pressure. At a 340 mm stroke, ensure the rod is not subjected to significant side loading; for off-axis loads, add an external linear guide or switch to a guided cylinder to prevent rod bearing wear and bending.
When replacing an existing cylinder, match these five points exactly: 50 mm bore, 340 mm stroke, PT1/4 port thread, basic mounting (no integrated bracket), and confirm whether a magnet (-S suffix) is needed for position sensors. This model uses the standard TPU seal and PT thread.
Quick checklist
At 0.5 MPa, the push force is 982 N. At 0.7 MPa, it increases to 1374 N. The maximum operating pressure is 1.0 MPa, which yields a theoretical push force of 200 kgf. Always calculate force based on your specific regulated pressure for safe operation.
No. The AirTAC SC series is a tie-rod cylinder and is dimensionally shorter than a standard ISO 15552 profile cylinder. It is not a direct replacement for ISO 15552. It is a direct replacement only for another AirTAC SC50 cylinder or a tie-rod cylinder with identical bore, stroke, port thread, and mounting dimensions.
