Blackened Motor Shaft

The Blackened motor shaft by Guanshuo factory adopts a high-temperature oxidation blackening process, forming a dense Fe₃O₄ oxide film on the surface of the shaft body. It has basic anti-rust and anti-oxidation capabilities and is suitable for the basic protection procurement requirements under normal working conditions. The simple process and high processing efficiency, along with the lower procurement cost compared to chrome-plated and hard alloy shafts, are the core considerations for bulk purchasing of general-purpose motor shafts. The blackened film layer is extremely thin only1−3μm, which does not change the original size, tolerance and fit accuracy of the shaft body. There is no need to reserve machining allowance, and it is suitable for the precision requirements of standard motor shaft procurement. The surface is matte black, without reflection or burrs. It is less likely to scratch bearings, oil seals and other accessories during assembly, enhancing the assembly stability of the entire machine and meeting the assembly standards for general equipment procurement. It is compatible with various conventional motor shaft base materials such as 45# steel, 40Cr, and Q235, without the need for special base material treatment, meeting the general requirements for purchasing motor shafts of multiple categories.
