The inner surface of SN-H steel bushing is processed with various types of oil grooves, which improves the surface hardness and wear resistance after heat treatment. It is suitable for heavy-duty joint parts of construction machinery such as excavators, rotary drilling rigs, large loaders, wall grab and so on.
Our steel bushing bearings are manufactured from premium materials including 45#, 40Cr, 20CrMo, and GCr15. From raw materials to finished products, each manufacturing process undergoes strict quality control to ensure superior product performance. This results in bushings with exceptional wear resistance, high surface hardness, and strong internal toughness.
