PURPOSE:To use effectively a lubricating oil, by composing a bearing of a synthetic resin serving as base resin into which a norbornane synthetic elastomer, oil transferring short fibers, a metal powder, and a solid lubricant are uniformly dispersed. CONSTITUTION:An oilless bearing 1 comprises the synthetic resin 7 serving as a base resin into which 1-40vol% lubricating oil, 0.1-20vol% norbornane synthetic elastomer 3 (that absorbs and carrys the lubricating oil), 5-30vol% lubricating oil transferring short fibers 4 (that act as agent for transferring the lubricating oil carried on the norbornane synthetic elastomer 3), 0.5-50vol% metal powder (that comprises sprayed kelmet powder or bronze powder), and 0.5-20vol% solid lubricant 6 are mixed. |
