摘要:
A metal bearing liner is formed by deep drawing press process sequentially subjecting a progressive sheet material (roll material) to a plurality of press processes. This makes it possible to form a metal bearing liner by a press work instead of a cutting work that has been conventionally employed while maintaining a requisite accuracy such as roundness and cylindricality thereby remarkably reducing the manufacturing cost of the metal bearing line thereby.
