Product information

Product features

Copper lubricant mosaic is made from medium or low base material and frictional surface layer is copper alloy with appropriate thickness. These two layers are closely linked. On the surface of the friction layer there are shallow holes (for silver with inner diameter> 200 mm) or through holes (for silver with inner diameter <200mm). In these holes contain solid lubricants, during work the friction surface will be lubricated by these solids.

Outstanding advantages:

- Material saving, high features, low price
- Low coefficient of friction
- High resistance to abrasion
- Long service life
