This series of machine types features dimensions and flange-type functions similar, capable of withstanding extreme axial loads and radial thrusts during operation. The output end features a raised fixed disk and a large-diameter through shaft, allowing for the integration of setting functions and static automation peripheral equipment. The power source's electrical, oil, and gas pipelines can be configured within the hollow bore. This series is widely used in various industrial machinery across industries that require heavy-duty, direct-connection automated equipment for intermittent automated drives.
