The SN-H steel bushing features various types of oil grooves on its 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 including high wear resistance, superior surface hardness, and robust internal toughness.
