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