  • Patent number: 10053645
    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.
