Because of its own advantages, cemented carbide bushings are widely used, mainly used for the support of rotating shafts, various pump bearing sleeves, motor shaft sleeves, and sealing sleeves. For drilling tools, it is called drilling casing, also known as bushing.
Carbide bushings have a wide range of applications and are a device for protecting a class of components. It has a lot to do with the role and purpose of its application environment in actual work. In valve applications, bushings are installed on the stem and bonnet to reduce valve leakage and provide sealing; in bearing applications, bushings are used to reduce wear between bearings and shaft seats, avoiding increased clearance between shafts and holes big wait.
