Description

Technical field

[0001] The present invention relates to sliding bearings, especially oil-free lubricating bearings; it is also related to the composition of polymer compounds. Background technique

[0002] The three-layer composite bearing in the oil-free lubricating bearing is created by the British Gracia Company, referred to as DU. The product is based on a sheet-shaped steel plate, with a spherical porous bronze powder layer sintered in the middle, and the surface is rolled with lead-based mixture mainly made of polytetrafluoroethylene (PTFE), which penetrates into and covers the above-mentioned copper powder layer and sinters to form a Anti-friction and wear-resistant layer. Finally, the above-mentioned three-layer composite sheet is rolled into sleeve-shaped bearings of different sizes according to the size of the shaft. The DU type bearings produced all over the world are SF-1 type in China, which have been widely used in high, medium load and low speed occasions. ...
