The cemented carbide wear-resistant bushing dedicated to the geology and mining field is made of cemented carbide material with high cobalt content and high hardness. It is used in key parts of geological exploration and mining equipment to provide wear resistance, impact resistance and sealing protection. It can effectively extend the service life of equipment under harsh working conditions (such as high wear, high pressure, and dusty environments), and is suitable for drilling rigs, roadheaders, conveying equipment, etc.
