What materials are sliding bearings made of?

Sliding bearings are made of a variety of materials. Common materials include bearing steel, stainless steel, brass, brass plus graphite, pure graphite, engineering plastics and other materials.

Among them, bearing steel is one of the most common sliding bearing manufacturing materials and has the advantages of high hardness and high wear resistance. Stainless steel has good corrosion resistance and high temperature performance, and is often used in high-precision, high-speed sliding bearings.

Brass is a common low-cost bearing material with good wear resistance and impact resistance. Brass plus graphite is a commonly used wear-resistant bearing material with good wear resistance and load-bearing capacity.

Pure graphite is a bearing material with good lubrication properties and can be used under harsh working conditions such as high speed and heavy load. Engineering plastic is a new type of sliding bearing manufacturing material. It has the characteristics of super wear resistance, waterproof, dustproof, anti-corrosion, high temperature resistance, low noise, self-lubricating and maintenance-free. It is widely regarded as a new generation of automatic bearings. The product of choice for lubricating materials.

In general, when selecting sliding bearing manufacturing materials, comprehensive considerations need to be made based on the bearing's operating conditions and performance requirements to select the most appropriate material.
