Bearings

Sliding bearing materials comprise a backing metal having a porous metal layer formed on the surface thereof where a composition is impregnated and coated into pores and onto the surface. The composition contains from 5 to 30% by volume of lead having a relative surface area of 1,000 to 8,500 cmÇ/g,...

Beschreibung
Zusammenfassung:	Sliding bearing materials comprise a backing metal having a porous metal layer formed on the surface thereof where a composition is impregnated and coated into pores and onto the surface. The composition contains from 5 to 30% by volume of lead having a relative surface area of 1,000 to 8,500 cmÇ/g, the remainder being PTFE. The composition can also contain from 0.5 to 30% by volume of at least one kind of solid lubricant such as a metal oxide, metal fluoride, graphite, a fibre material such as carbon fibre or glass fibre, and a ceramic material such as SiC. The total of the components, other than the PTFE can then total 5.5 to 50% by volume. The sliding material is made by impregnating the composition and baking in a non-oxidising (e.g. neutral or reducing) atmosphere.
