Kind Code:
B2
Abstract:
Provided is a bearing for a motor-type fuel injection pump. This bearing is composed of a Cu—Ni-based sintered alloy, inexpensive and has a superior corrosion resistance and abrasion resistance. The bearing contains 10 to 20% by mass of Ni, 2 to 4.5% by mass of Sn, 0.05 to 0.4% by mass of P, 2 to 7% by mass of C, and a remainder consisting of Cu and inevitable impurities. The bearing has a metal structure where Sn is uniformly dispersed and distributed in a metal matrix, and has a porosity of 7 to 17% where a free graphite is dispersed and distributed in pores.
