The difference between non-metallic sliding bearings and metallic sliding bearings

Sliding bearing work is sliding friction; rolling friction depends on the size of the manufacturing accuracy; and the size of the sliding bearing friction depends mainly on the bearing sliding surface material. Sliding bearings are generally self-lubricating work surfaces; sliding bearings in accordance with the material is divided into non-metallic plain bearings and metal sliding bearings.

Non-metallic plain bearings mainly plastic bearings, plastic bearings are generally made of relatively good performance engineering plastics; more professional manufacturers generally have engineering plastics self-lubricating modification technology, through the fiber, special lubricants, glass beads And so on the engineering plastics self-lubricating enhanced modification to achieve a certain performance, and then re-use of modified plastic processed into self-lubricating plastic bearings.
Metal sliding bearing is the most commonly used three-layer composite bearing, this bearing is generally based on carbon steel substrate, sintering technology by sintering a layer of spherical copper powder on the plate, and then sintered layer of copper powder layer 0.03mm PTFE lubricant; wherein the middle layer of spherical copper powder is the main role is to enhance the bonding strength between the steel and PTFE, of course, also play a role in carrying and lubrication work;
In recent years, there are also a number of outstanding small and medium-sized enterprises emerging in the world's sliding bearing manufacturing base. The comprehensive strength of large enterprises is strong. With the development of the sliding bearing industry, the industry has become more and more subdivided, and the small and medium enterprises Big business gap.
It is not difficult to see through the above description, the plastic bearing and metal sliding bearing the following differences: 1, plastic bearings are lubricated material as a whole, long service life; and metal sliding bearing lubrication layer is only 0.003mm surface PTFE, when this thin The end of the layer of friction also declare the end of life; 2, the use of plastic bearings will not occur rust and corrosion-resistant, and metal rust-prone bearings can not be used in chemical liquid; 3, the quality of plastic bearings than metal Light, which is more suitable for the modernization of lightweight design trends; 4, plastic bearing manufacturing costs lower than the metal; plastic bearings using injection molding processing is more suitable for mass production; 5, plastic bearings in operation without any Noise, has a certain vibration absorption function; As the plastic bearing metal sliding bearing there are many advantages, the plastic bearing production is expanding, the use of plastic bearings are also constantly extending the range of applications, from fitness equipment to office equipment and the automotive industry Dengjun used plastic bearings, cars on the road without using plastic bearings. Plastic bearings unlimited market prospects!
