Boundary Lubricating Bushes

1. SF-2 is a kind of thin wall wrapped bearings made of
triple layer composite material which consists of a low-
carbon steel backing strip, a sintered porous tin bronze
particles interlayer and rolling process with POM as
surface layer. The covering layer has pockets to retain
lubricating grease.
2. Suitable for slow rotational and oscillating movements
and also linear movements under radial load and
maintenance-free operation but also where there is a
risk of errors of alignment, edge loading or moderate
contamination. Initial lubrication required.
