This series of machines features dimensions and flange-type functions similar, capable of withstanding oversized axial loads and radial thrust forces during operation. It features a raised fixed disk and a large-diameter through-shaft at the output end, allowing for the integration of setting functions and static automation peripherals. Power sources, such as electrical, oil, and gas pipelines, can be configured within the hollow bore. This series is widely used in various industrial machinery across industries for heavy-load, direct-connection automation equipment, serving as intermittent drive for automation.
