Slide bearing, has lubricating layer divided into three regions along thickness at different metal contents, where sliding region facing region is provided with lower metallic content and smaller thickness than another region

摘要

The bearing has a metallic support part (3) including a sintered porous lubricating layer with a metallic portion (MA) and a portion of polymeric filler. The lubricating layer is divided into three regions (I, II, III) along thickness (t) at different metal contents. One of the three regions is provided with a predetermined higher metallic content and smaller thickness than another region with the metallic portion facing toward the support part. A sliding region facing the third region is provided with lower metallic content and smaller thickness than the latter region. An independent claim is also included for a method for manufacturing a slide bearing.
