The difference and application of copper sleeves and bearings

Copper sleeve, also known as copper bearing, requires lubrication of the bearing with oil. It is made of various copper alloys for lubricating mechanical parts. It is an important 

component of various large and heavy machinery. Bearings can withstand both radial and axial forces, but copper sleeves cannot simultaneously possess both. But the advan-

tage of copper sleeves is that they can prevent sparks from being generated when components collide, and can prevent explosions of flammable and explosive gases or other 

liquids. 

Bearings ("bearings", Japanese called "shaft bearings") are parts that fix and reduce the friction coefficient of loads in mechanical transmission processes. It can also be said 

that when other components generate relative motion on the shaft, it is used to reduce the friction coefficient during power transmission and maintain the fixed position of 

the shaft center. Its main function is to support mechanical rotating bodies and reduce the friction coefficient of mechanical loads during the transmission process of equi-

pment. According to the different friction properties of the moving components, bearings can be divided into two categories: rolling bearings and sliding bearings.

Copper sleeves are mainly used to reduce friction and are installed on shafts to support axial loads and reduce friction. And bearings are used to support and rotate the 

shaft, directly supporting sliding friction and supporting rotational loads. The structure of copper sleeves is relatively simple, generally cylindrical, with smooth and flat inner 

and outer surfaces; The bearing is composed of multiple components, including an inner ring, an outer ring, rolling elements, and a cage.

In terms of manufacturing materials, copper sleeves are mainly made of materials such as brass, bronze, phosphor bronze, aluminum bronze, zinc aluminum alloy, etc. The 

manufacturing materials of bearings include non-ferrous metals, non-metallic materials, synthetic materials, etc
