Sliding bearing material performance characteristics

Bearing contact part as the sliding bearing and shaft neck, shape for tegular half cylinder, very smooth, usually made from bronze, anti-friction alloy wear-resistant materials such as, under special circumstances, can be made from wood, engineering plastic or rubber. Bearing in the process of using, also played a big role in bearing, the bearing shell material performance has certain characteristics, below the bearing network to share knowledge. Bearing material performance characteristics mainly include the following: 1, the anti-friction property: vice material has lower friction coefficient. 2, wear resistance, the anti-wear properties, usually expressed as a wear rate. 3, bite viscous resistance ( Agglutination) : materials, heat resistance and adhesion resistance. 4, friction compliance: material through elastic-plastic deformation to compensate for the bearing surface of sliding surface of the initial poor ability. 5, embeddedness: embedded materials for hard particles, so as to reduce the bearing sliding surface scratch or abrasive wear performance. 6, running-in, bearing and shaft neck surface after short-term light load operation, form the shape and the roughness of the surface of the match capacity ( Or property) 。 7, moreover also should have sufficient strength and corrosion resistance, good thermal conductivity, manufacturability and economy. Sliding bearing material type: the bearing shell materials commonly used are: metal materials, non-metallic materials and powder metallurgy materials bearing generally adopt bearing alloy (metal materials Babbitt, white metal) Is composed of tin, lead, antimony, copper alloy; Copper alloy, its main divided into two categories, bronze and brass; With ordinary grey cast iron, ductile iron, etc. Bearing non-metallic materials such as plastic, hardwood, rubber, including plastic use most bearing shell powder metallurgy materials by powder, such as copper, iron, graphite through pressing, sintering and become more porous bearing shell material.
