SOLID LUBRICATING ROLLING BEARING

摘要

PURPOSE:To improve the durability and low dusting characteristics in a solid lubricating rolling bearing. CONSTITUTION:Microscopic projecting and recessed parts 1b1 and 1b2 created by mechanical work exist on a rolling travel surface and a collar surface of an inner ring 1, and among them, the projecting part 1b1 has a smooth tip part. The recessed part 1b2 is formed in a wedge shape turning inside a base material. These projecting and recessed parts 1b1 and 1b2 run in a stripe shape on the rolling travel surface and the collar surface. A lubricating coat 1a is formed in an island shape on a surface (rolling travel surface and collar surface) of the inner ring 1.
