What do you know about engine bearing?

In the engine, whether the main shaft or the body, the replacement cost after wear is very high. For this reason, a component that is easy to replace and cost-effective, namely the bearing shell, has been added between the spindle and the seat hole.Engine bearings, also known as sliding bearings, are mainly used to support the load and transmission movement between the crankshaft and the base.  Bearing shells can not only reduce the friction and wear between the shaft and the bearing, but also play the role of supporting the shaft to ensure that the rotating shaft can run smoothly.

The performance requirements of bearing shells require their materials to have the following characteristics:

a. Enough mechanical strength and plasticity;

b. Strong wear resistance, corrosion resistance and adhesive resistance;

c. Low friction coefficient;

d. Good thermal conductivity and low coefficient of thermal expansion;

As usally,the bearing material include :metal materials, powder metallurgy materials, and non-metallic materials.The bearing shells produced by Dafeng Mingyue Bearing Bush Co., Ltd are made of metal materials, especially Bi-Metal Bearings and Tri-Metal bearings.
