Abstract
A bearing with strength and abrasion resistance for a flow rate control valve of an exhaust gas recirculation system of an internal combustion engine. By using a sintered Cu alloy with a composition consisting of, by mass %, Ni: 10 to 30%, Sn: 5 to 12%, C: 3 to 10%, P: 0.1 to 0.9% and Cu and inevitable impurities as the balance, the bearing exhibits a thermal expansion coefficient corresponding to that of a shaft made of austenitic stainless steel. As a result, a bearing with strength and abrasion resistance under high temperature conditions is obtained.
