Sliding element, semi-cylindrical sliding bearing with it and method of manufacturing a sliding element.

摘要

A sliding member which can be easily machined and whose accuracy can be easily secured even after enlargement, a semi-cylindrical sliding bearing employing the same, and a method of manufacturing the sliding member are provided. The sliding member is a plate-shaped sliding member (10) used for a semi-cylindrical sliding bearing. The sliding element (10) is equipped with wide areas (11, 12 and 13) and at least one narrow area (21, 22). A narrow area (21 or 22) is arranged between in each case two of the wide areas (11, 12 and 13), the overall length of the narrow areas in their width direction being smaller than that of the wide areas (11, 12 and 13), and whose hardness is higher than that of the wide ranges (11, 12 and 13). When it is assumed that one end in the thickness direction is the one end part and the other end in the thickness direction is the other end part, each narrow area (21, 22) includes a one-side end face exposed to the one end part , and another side end surface. The other-side end face is exposed to the other end part and has a smaller exposed area than the one-side end face. In the narrow region, the total length of the other-side end surface in the width direction is smaller than the entire longitudinal direction. The maximum width of the narrow portion is 0.1 to 5.0% of a total length of the slider including the wide portions and the narrow portion in the width direction.
