SF-58 Wrapped bearings of solid lubricant

Application characteristics：It's a kind of steel-lead bronze alloys based bearing which is embedded with particular formulation of solid lubricants. Owing to the high strength, high load capacity and the spirally distributed diamond type of the embedded solid lubricant, the high. Temperature lubricating action and wear resistant action as extraordinary exploited. The lubrication area of the bearing surface is being about 25%. This type of bearing is particularly applied in starting motor for automobiles, generators, hoisting machines, various cranes and those machines in metallurgical industry.
