Self-lubricating bearings are divided into composite self-lubricating bearings, solid inlaid self-lubricating bearings, bimetallic self-lubricating bearings and special material self-lubricating bearings.
One of the large class of solid inlaid self-lubricating bearings (JDB) is a new type of lubricating bearing which has both the characteristics of metal bearing and oil-free bearing. It is loaded by metal matrix and lubricated by special formulation of solid lubricating materials.
It has the characteristics of high bearing capacity, impact resistance, high temperature resistance, strong self-lubrication, etc. It is especially suitable for heavy load, low speed, reciprocating or swinging difficult to lubricate and form oil film occasions, and is not afraid of water erosion and other acid etching and scouring, products have been widely used in metallurgical casters, rolling equipment, mining machinery, molds. In the production line of tools, lifting machinery, textile machinery, wind power generation, ships, steam turbines, water turbines, injection molding machines and equipment.
