The inner surface of SN-H steel bushing is processed with various types of oil grooves, which improves surface hardness and wear resistance after heat treatment. This makes it suitable for heavy-duty joint parts of construction machinery including excavators, rotary drilling rigs, large loaders, wall grabs, and similar equipment.
Our steel bushing bearings are manufactured using premium materials including 45#, 40Cr, 20CrMo, GCr15 and other specialized alloys. Every manufacturing process from raw materials to finished products undergoes strict quality control to ensure exceptional product performance. The result is bushings with high wear resistance, superior surface hardness, and strong internal toughness.
