ROLLER AND CAGE ASSEMBLY, ROLLER BEARING AND CAGE ASSEMBLY, AND CAGE

摘要

Provided are a roller and cage assembly and a bearing which employs the roller and cage assembly. The roller and cage assembly is surface treated to have a film which causes no increase in stress and never peels off from the cage even if the film is thick, and which will not be affected by an additive in the oil employed. The roller and cage assembly is further adapted to prevent the wear of the cage when the cage is used for a large displacement engine or the like, and provide an improved adhesion of a surface-treated layer to a base material. The cage (2) is plated to form a primary plated layer (4) on the surface, and further plated to form a plated multilayer (5) on the surface of the primary plated layer (4), the plated multilayer (5) including a plurality of plated layers. The plated multilayer (5) has a Ni/PTFE plated layer formed on the surface of the primary plated layer (4), another plated layer which is formed on the surface of the Ni/PTFE plated layer and has the same plating as that of the primary plated layer (4), and an Ni/PTFE plated layer formed on the surface of the another plated layer.
