ActiveSpecification of plastics-bronze-steel backing triplelayer self-lubricating materials - Part 2：plastic overlay with modified POM
塑料－青铜－钢背三层复合自润滑板材技术条件 第2部分：带改性聚甲醛（POM）减摩层的板材
Application Summary AI generated
This standard specifies the technical requirements for a self-lubricating composite material consisting of a steel backing, a sintered bronze interlayer, and a modified polyoxymethylene (POM) plastic overlay. It is applied in the manufacturing of maintenance-free sliding bearings and wear plates used in automotive, agricultural machinery, and light industrial equipment where low friction and high load capacity are needed without external lubrication. The standard ensures consistent quality for components operating in dry or marginally lubricated conditions, such as suspension bushings, gearbox shift forks, and hydraulic pump wear surfaces.
