Bimetallic self-lubricating bearing (is made of high quality low carbon steel plate, bronze plate or stainless steel plate)

steel plate as the substrate, the surface sintered spherical bronze powder as the intermediate transition layer, while sintered rolled containing solid. The sintered spherical bronze powder is used as the intermediate transition layer, while the sintered rolled copper alloy containing solid lubricant (the main component is graphite) is used as a self-lubricating composite bearing material. The material is a self-lubricating composite bearing material, which is rolled into a sliding bearing. The material has self-lubricating, high load-bearing capacity, friction and wear reduction performance.

The material has the advantages of self-lubrication, high bearing capacity, good friction and wear resistance, wide range of applicable temperature and medium, simple structure, compact size, and can work under oil-free lubrication for a long time. The material has the advantages of self-lubrication, high bearing capacity, good friction and wear reduction, wide range of applicable temperature and medium, simple structure, compact size, and can work under oil-free lubrication for a long time.

Bimetallic self-lubricating bearings are divided into steel-based, copper-based and stainless steel-based (FzF063).

Three kinds of bimetal bushing

1 material structure

2. Typical features

Suitable for low speed, heavy load or intermittent motion conditions, where the lubricant film cannot be formed or maintained.

, applicable to the working environment or mechanical structure restrictions, it is difficult to supply oil lubrication occasions.

Suitable for various forms of motion such as rotary, reciprocating, oscillating and linear motion, as well as the need for frequent starting or under high load. The occasion of starting. Suitable for working under high or low temperature, or the occasion of wide range of ambient temperature change.

Good corrosion resistance, can be used in corrosive media such as seawater and other chemical liquids or gases, as well as in water containing mud and sand or in radioactive environments.

Water or radioactive environment. non-absorbent, good dimensional stability, high mechanical strength, and good thermal conductivity.

The bearing is thin-walled structure, light weight, occupying small volume, suitable for compact design.

Compared with the traditional three-layer composite material, the static load characteristics, wear resistance under the condition of no grease lubrication, The bearings are of thin-walled structure, light in weight and small in size.

Compared with copper-based inlay self-lubricating material, it is more suitable for small angle oscillation conditions and is cheaper.
