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.
The steel bushing bearing of our company is based on 45#,40Cr, 20CrMo, GCr15 and other materials. From raw materials to finished products, each process is strictly controlled to ensure the product quality. it produces bushing with high wear resistance, high surface hardness and strong internal toughness.
