STAINLESS STEEL BUSHING SUPPORT MATERIAL
Support material Stainless steel ( SUS-316 / SUS-304 )
Intermediate layer Sintered bronze
Sliding layer PTFE+Oil Fiber
WRAPPED STAINLESS STEEL BUSHING SUPPORT MATERIAL STRUCTURE
structure
1.PTFE、 polymer fibres mixture 0.01~0.03mm, lead-free provides an excellent initial transfer film,
which effectively coats the mating surface of the bearing assembly, forming an oxide type solid lubricant film.
2.Sintered bronze powder 0.20-0.35mm, provides max. thermal conductivity away from the bearing surface,
also serves as a reservoir for the PTFE mixture.
3.Stainless steel backing, provides high load carrying capacity, very high level of resistance in corrosive environments.
