ActiveSpecification of Plastics-Bronze-steel backing triplelayer self-lubricating materials - Part 1：plastic overlay with modified PTFE
塑料－青铜－钢背三层复合自润滑板材技术条件 第1部分：带改性聚四氟乙烯（PTFE）减摩层的板材
Application Summary AI generated
This standard specifies the technical requirements for a three-layer self-lubricating composite material consisting of a steel backing, a sintered bronze intermediate layer, and a modified PTFE plastic overlay. It is applied in the manufacturing of maintenance-free sliding bearings and wear plates used in automotive, agricultural machinery, and general mechanical systems where low friction and high load capacity are required without external lubrication. The standard ensures consistent quality and performance for components operating under dry or marginally lubricated conditions.
