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.
