Advanced Boundary Lubrication Bushings

Definition

The boundary lubricated bearing is a bearing that works by an extremely thin lubricating film between the bearing and the shaft. The film is formed by the adsorption of lubricant molecules, which can separate the metal surface. Under unsatisfactory working conditions, it can also reduce friction and wear to ensure the mechanical operation. It is used in many fields such as automobiles and machinery.
