This series of machines features similar size design characteristics and flange-type functions, capable of withstanding large axial loads and radial thrust forces during operation. The output end features a raised fixed disk and a large-diameter through-bore shaft, which can be paired with set functions and static automation peripheral equipment. Power sources such as electrical, oil, and gas pipelines can be set 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 drives for automation.
