The SN-H steel bushing features an inner surface processed with various types of oil grooves, enhancing surface hardness and wear resistance after heat treatment. This makes it ideal for heavy-duty joint parts in construction machinery including excavators, rotary drilling rigs, large loaders, and wall grab equipment.
Our steel bushing bearings are manufactured from premium materials including 45#, 40Cr, 20CrMo, and GCr15. Every production process—from raw materials to finished products—undergoes strict quality control to ensure superior performance. The result is a bushing with exceptional wear resistance, high surface hardness, and robust internal toughness.
