Abstract: A bearing bush 1 for use in a toggle has a cylindrical metallic base material 2 and a solid lubricant 3 embedded in the metallic base material 2, and the metallic base material 2 has dead end grooves 5 formed in a cylindrical inner peripheral surface 4, an annular groove 6 formed in the cylindrical inner peripheral surface 4, and circular holes 7a and 7b as well as 7c and 7d formed in each of a pair of semicylindrical inner peripheral surfaces 4a and 4b adjacent to each other in an axial direction X and two pairs of semicylindrical inner peripheral surfaces 4c and 4d sandwiching the pair of semicylindrical inner peripheral surfaces 4a and 4b in a circumferential direction R and adjacent to each other in the axial direction X in each pair.

Abstract: High-strength brass alloy having superior wear maintains single-structure ? phase and Fe—Cr—Si-based intermetallic compounds dispersed in the ? phase. A high-strength brass alloy for sliding member comprises Zn from 17% to 28%, Al from 3% to 10%, Fe from 1% to 4%, Cr from 0.1% to 4%, Si from 0.5% to 3%, mass ratio, and the remnant including Cu and inevitable impurities. The high-strength brass alloy has structure in which the matrix shows single-phase structure of ? phase and Fe—Cr—Si-based intermetallic compounds are dispersed in the ? phase. The high-strength brass alloy for sliding member has the structure in which the matrix shows single-structure of ? phase and hard Fe—Cr—Si-based intermetallic compounds are dispersed in the ? phase. Thus the hardness is increased and wear resistance is improved.
