Properties
DP4B plate & DP4B stripé”›å²uitable for dry running, low coefficient of friction, lowerè½wear, good sliding characteristics, the transfer filmè½created can protect the mating metal surfaces, suitableè½for rotating and oscillating movement, high chemicalè½resistance, low absorption of water and swelling. DP4B materieal improved the friction and much good wearè½resistance over the common SBU bearing range underè½lubricated operation.
