TOB02 Boundary lubrication bushing is based on steel as matrix, middle sintering spherical bronze powder, surface rolled modified POM (POM), and contain storage pits. It is suitable for normal temperature conditions, the low-contained place, replace the traditional copper sleeve both to reduce costs and extend service life. On the rolling mill use, to save fuel frequency, simplifying replacement program.
Pedal assembly, balance bushings, brake calipers, steering main pin sleeve jacket and truck tailgate, truck, crane, truck cranes, forest machinery, packaging machinery, construction machinery, hydraulic motors, agricultural machinery and mining machinery, metallurgy machinery, irrigation machinery, automobile, steel rolling industries.
