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 using premium materials including 45#, 40Cr, 20CrMo, GCr15 and other high-quality steels. From raw materials to finished products, each manufacturing process is strictly controlled to ensure superior product quality. This results in bushings with exceptional wear resistance, high surface hardness, and strong internal toughness.
