SF-7 Oil-retaining
bearings
|
|
Application characteristics£ºIt's
made bronze or iron powder, mold pressed under high pressure
and then sintered under high temperature, and oil is soaked
into the homogeneously spreaded tiny pores of the metal under
vacuum. It's used in domestio electric appliances, electric
tools, textiles machinery.

Provide non-standardized products£ºCylindrical bushes, flanged
bushes, half bearing, wear plate.
|
SF-80 Point-lubricating
bearings
|
|
Application characteristics£ºMetal backed bronze
with graphite lined bearing materials, sintered layers are
of special copper alloy containing uniformly dispersed solid
lubricants. Suitable for hostile environments, for high load
application which lubricants. Suitable for hostile environments,
for high load application which lubrication, is difficult.
Used in water turbines, injection molding machinery, packing
machines, construction equipment, tire moulds etc.
