Bushes with acetalic resin without lead

Boundary lubrification 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 prolonge working life when replacing normal all copper sleeves. It is widely applied in auto chassis, forging achine, metallurgical and mining machine, civil engineering, power station, strip rolling industries, etc.
