SF-2 boundary lubrication bushing
is based on a composite material with 3 firmly bonded
layers: steel as backing, sintered bronze spherical
powder as interlayer and modified POM as lining
layer. It fits well for low speed, heavy duty and
normal temperature and saves cost and prolongs working
life when replacing normal all copper sleeves. It
is widely applied in auto chassis, forging machine,
metallurgical and mining machine, civil engineering,
power station, strip rolling industries etc.
