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.
Our steel bushing bearings are manufactured from high-quality
materials including 45#, 40Cr, 20CrMo, GCr15 and others. From raw
materials to finished products, each manufacturing process is
strictly controlled to ensure superior product quality. This
results in bushings with high wear resistance, exceptional surface
hardness and strong internal toughness.
