Material: Brass. This material is recognized by its characteristic golden color. Brass is often used because of its good corrosion resistance, low coefficient of friction, and ease of machining. Machining method: These parts are precision machined, most likely through CNC Turning due to their circular symmetry and precise threads/slots. Geometry: Basic shape: Hollow cylinder, with a flange/flange at one end. External thread: Threading or knurling/serrations in the body of the cylinder, indicating that the part is designed to screw into another part, or to improve grip/hold inside a bore. Hollow bore: The center is hollow, used to contain a shaft, cable, or fluid. Flange: Has a large flat surface at one end, with screw/locating holes (about 3-4 holes) to fix the part to the machine frame, housing or other flat surface. Cut-out: A part of the cylindrical body is cut out (flat/cut-out), which can be used to fit another part that is not round in shape (anti-rotation), or to provide a way for cables/oil. Applications (Capabilities): Industrial Machinery/Precision Mechanics: Used as bearing bushes, gearbox housings, valve components, or coupling parts in pumps, hydraulic systems, or machines that require resistance to friction and corrosion. Electrical/Electronic: Can be a housing or coupling part in high voltage equipment or environments that require good electrical conductivity.
