Abstract
A sliding bearing which is suitable for and durable in the use under high load of sliding in rocking motion, and the structure of bearing is not complicated so as to facilitate the manufacturing. The alloy used for making the bearing is composed of iron-based sintered alloy having quenched structure, and the bearing surface is provided with inclined grooves of an inclination angle of 10 to 40° relative to the direction perpendicular to the sliding direction and a width of 2 to 8 mm and the area of inclined grooves is 50% or less of the total inner bearing surface and an imaginary line perpendicular to the sliding direction crosses both the inclined groove and the bearing surface at any position of the inner surface of bearing. When the bearing is used, at least the inclined grooves are impregnated with a lubricant.
