1 Scope


This standard specifies the basic requirements for multilayer materials used for the manufacture of thin-walled plain bearings (liners, bushings, thrust washers). The layered material consists of steel backing and a layer of bearing material (cast, sintered, rolled). Possible running-the layer obtained by electrolytic deposition.

Note — the environmental Impact will limit the use of certain materials such as lead.

3.2 Steel Foundation

Chemical composition of steel for the base is determined by agreement between the manufacturer and the consumer. Mainly used mild steel.

For composite materials, bronze / polymer indicated in table 4, as the basis can be used steel with a copper coating.

3.3 Bearing layer

Bearing layer based on tin and lead must meet the requirements specified in table 1.

The bearing layer of copper-base shall conform to the requirements specified in table 2.

Bearing layer on the basis of aluminum shall conform to the requirements specified in table 3.

Bearing layer on the basis of sintered bronze and polymers must meet the requirements specified in table 4.

Note — Developed new materials based on aluminum, containing aluminum and silicon or manganese, as well as soft materials such as lead or tin.

3.4 Running-the layer corresponding to the requirements specified in table 5, can be used for bearing layers, as shown in table A. 2.

The thickness of the running-layer and any intermediate layers between the bearing layer and running-in layer is determined by agreement between the manufacturer and the consumer.

3.5 Properties and selection of materials

Recommendations on the hardness of the bearing material in the form of a strip and the use of bearing materials is given in Appendix A.

ГОСТ ИСО 4383-2006 Подшипники скольжения. Многослойные материалы для тонкостенных подшипников скольженияHardness values for material of the shaft are minimal and are valid for application in high-speed machines. Operating conditions, particularly lubrication conditions, play a significant role, therefore it may be necessary for a significant difference in hardness between the bearing material and the shaft.
