JF806 Steel Sintered Metal Bearings CuZn25Al6Fe3Mn3 Solid Lubricant Plugs
JF-806 bimetal bearing is made of Steel +Bronze+Solid lubricant .
Material Features
The microstructure of the steel and bronze interface shows there have intermetallic diffusion between 3u to 5u during the casting
process. This ensures perfect adhesion and in every case, the mechanical properties of the interface are superior to those of
bronze itself.
This intermetallic diffusion offers excellent mechanical properties and with partial transfer of load to the steel. The thin bronze
layers allows the material have closed thermal expansion thus is accept the final production have heating process in case of, that
means SB-GT material can keep the accurate and constant mechanical clearance.
