Patent ID: 8690438

Claim:
A sliding bearing comprising: a metallic outer ring member, and a self-lubricating liner formed on an inner circumferential surface of the outer ring member, the self-lubricating liner being a self-lubricating resin composition comprising: 60 to 80% by weight of a polyetherketone-based resin, 10 to 30% by weight of polytetrafluoroethylene having a molecular weight of not less than 1,000,000, 10 to 25% by weight of added fibers consisting of 5 to 15% by weight of a polyacrylonitrile-based carbon fiber, and 5 to 15% by weight of aramid fiber; wherein: the self-lubricating resin composition contains no graphite, and the inner circumferential surface of the outer ring has a surface roughness in terms of center line average roughness not less than R a 4.0 μm and a surface roughness in terms of maximum height not less than R max 30.0 μm.
