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