3D Machinery Part Model With Circular Flange And Central Hole

This 3D machinery part model drawing presents a circular mechanical component designed with a stepped flange profile and a central cylindrical hole used for assembly connections. The model shows a round base structure with multiple concentric stepped layers forming the outer geometry of the machinery part. Around the upper flange surface, a circular pattern of bolt holes or fixing points is illustrated, which supports mechanical fastening or mounting to other machine components. The central circular opening forms the main shaft passage, allowing rotational or mechanical connection with other parts of the equipment. The stepped outer profile improves structural strength and ensures proper alignment when the part is installed within a mechanical assembly system.
