Abstract: There is provided a resin composition for a machinable liner of a sliding member. An ultraviolet curable resin composition for a self-lubricating liner contains a (meth)acrylate compound having an isocyanuric acid ring represented by the following formula and PTFE as a solid lubricant. In the formula (1), X is a group which contains an acryloyl group and is composed only of C, H, and O. Y and Z are groups each composed only of C, H, and O. PTFE is contained in an amount of 10 to 50% by weight with respect to a total amount of the ultraviolet curable resin composition. The ultraviolet curable resin composition is suitable for a self-lubricating liner 24 of a spherical bearing 20 having an outer race 22 and an inner race 26.

Abstract: A sliding bearing having a metallic outer ring and a self-lubricating liner formed on the inner circumferential surface of the outer ring. The self-lubricating liner has a self-lubricating resin composition consisting of a mixture of 60 to 80% by weight of polyetherketone-based resin, 10 to 30% by weight of polytetrafluoroethylene, 5 to 15% by weight of carbon fiber, and not more than 15% by weight of aramid fiber, a total amount of the carbon fiber and the aramid fiber being 10 to 25% by weight. The inner circumferential surface of the outer ring has a surface roughness in terms of center line average roughness not less than Ra 4.0 μm and a surface roughness in terms of maximum height not less than Rmax 30.0 μm; and the outer ring and the self-lubricating liner are unified. A method of producing the bearing is also provided.
