[Application Features] SF-2X boundary lubrication bushing is based on steel backing, sintered bronze spherical powder, surface rolled modified POM (POM), and contain storage pits. It is suitable for normal temperature conditions, the low-contained place, to 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. [Application] The product has been widely used in main parameters maximum load pressure auto chassis, forging machine, metallurgical and mining machinery, engineering machinery, utilities, steel rolling industries: 70N / mm2 friction coefficient μ: 0.05 ~ 0.25 Temperature range : -40 ℃ ~ 130 ℃ Highest sliding velocity: 2.5m / s to allow the maximum PV value: 22N / mm2.m / s
