Patent ID: 11199223

Abstract:
A sliding member for a journal bearing is provided. A sliding layer includes fibrous particles dispersed in a synthetic resin, and has a sliding surface side region and an interface side region. The particles have an average particle size Dsur, axi and Dsur, cir respectively in an axial and circumferential cross-section in the sliding surface side region, and Dint, axi and Dint, cir respectively in axial and circumferential cross-sections in the interface side region. Dsur, axi and Dint, cir are 5-30 μm, and Dsur, cir and Dint, axi are 5 to 20% of respectively Dsur, axi and Dint, cir. A dispersion index of the particles having the major axis length of 20 μm or longer is 5 or more, both in the sliding surface side region in view of the axial cross-section and in the interface side region in view of the circumferential cross-section.
