Metallic self-lubricating bearings


Self-lubricating bearings are divided into composite material self-lubricating bearings, solid-inlaid self-lubricating bearings, bimetallic self-lubricating bearings, and special material self-lubricating bearings. Different self-lubricating bearings are selected according to different uses and working conditions.

Non-metallic self lubricating bearings


One of the major types of solid inlaid self-lubricating bearings (JDB for short name) is a novel lubricating bearing that combines the characteristics of metal bearings and oil-free lubrication bearings. The metal matrix bears the load, and the specially formulated solid lubricating material plays the role of lubrication.

 

It has the characteristics of high bearing capacity, impact resistance, high temperature resistance, and strong self-lubricating ability. It is especially suitable for heavy load, low speed, reciprocating or swinging and other occasions that are difficult to lubricate and form an oil film. It is not afraid of water wash and other acid erosion. And scour. The products have been widely used in metallurgical continuous casting machines, rolling equipment, mining machinery, molds, lifting machinery, textile machinery, wind power generation, ships, steam turbines, water turbines, injection molding machines and equipment production lines. The wear resistance is twice that of ordinary bushings.

 

The advantages of self-lubricating bearings (oil-free bearings), most of the bearings used in various machinery industries are balls, needles and the like, but a small part of them have adopted self-lubricating bearings. It is believed that lubricated bearings will become the dominant bearing in the near future.
