SF-58 固体润滑卷制轴承 Wrapped bearings of solid lubricant

应用特点：SF-58轴承是以SF-30双金属材料为基体，再埋入特殊固体润滑剂制作而成的新颖滑动轴承。由于高强度承载的合金材料作基体，理想的并经过严格选别的高分子填充材料为耐磨剂，合理的螺旋角度菱形块状均分布的润滑面，润滑面积达25%，因此，能发挥超群的低摩擦，良好的润滑性和抗磨耗性。产品适用于汽车起动电机、发电机、升降机、吊车及冶金机械等行业。 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.
