NTB-80 雙金屬卷制軸承 / Bi-metal Self-lubricating Bearing
NTB-80 Series
Substrate characteristics
High quality low carbon steel substrate, lead-free copper alloy surface of the sintered material as a bearing surface, the surface layer of the alloy can be processed all types of sump hole or hole for use under oil lubrication conditions. This lead-free copper alloy steel base material exhibits excellent load carrying capacity, good wear resistance and corrosion resistance properties. Because the material does not contain lead, so to meet the EU about cars 2000/53 / EC of the Directive
