PROBLEM TO BE SOLVED: To provide a cylindrical sliding member excellent in wear resistance, scuff-resisting sliding characteristics, and workability, and less aggressive to a counter sliding member, and also to provide a method for manufacturing the cylindrical sliding member.SOLUTION: A cylindrical sliding member contains ferrous particles in an aluminum-alloy base material. The ferrous particles are dispersed and exposed in an inner circumferential sliding surface at the rate of 25% or more and 60% or less in area ratio. Preferably, a sieve mesh opening degree of particle sizes of the ferrous particles is 0.5 mm or more and 2.36 mm or less. Preferably, the ferrous particles are of cast iron or steel. The cylindrical sliding member includes a cylinder liner. The cylindrical sliding member is manufactured by means of centrifugal casting. |
