The steel bushing is primarily made of materials such as 45#, 40Cr, 20CrMo, 20CrMnTi, 16Mn, and GCr15. The inner surface is machined with various oil groove patterns, and after heat treatment, the surface hardness and wear resistance are enhanced. It is suitable for heavy-duty joint positions in construction machinery such as excavators, rotary drilling rigs, large loaders, and diaphragm wall grabbers. From raw materials to finished products, every process is strictly controlled to ensure product quality, producing bushings with high wear resistance, high surface hardness, and strong internal toughness.
