  • SLIDING MEMBER AND METHOD FOR MANUFACTURING SLIDING MEMBER
    Publication number: 20150055899
    Abstract: According to the manufacturing method of a bearing which is a sliding member, a bimetal sintered alloy is formed by sintering a metal powder on a surface of a back metal which is a plate shaped metal member to form a sintered layer. In addition, following this, the sintered alloy is molded as a cylindrical bush and the bush undergoes a heat treatment. Following this, the bearing is formed by press-fitting the bush into a collar which is a cylindrical metal member.
