The invention relates to a rolling bearing having two concentric rolling rings which are rotatably supported by at least one row of rolling bodies and have a raceway for the rolling bodies of the at least one row of rolling bodies, and to a material handling and/or construction machine having such a rolling bearing, such as a crane or a tower cable excavator. According to the invention, different raceway modifications are provided in different angular sectors of the rolling ring and/or raceway modifications are provided only in a fraction of the circumference of the rolling ring. 本发明涉及一种具有两个彼此同心的滚动圈的滚动轴承，所述滚动圈彼此可旋转地通过至少一排滚动体彼此支撑并且具有用于所述至少一排滚动体的滚动体的滚道，以及涉及一种具有这种滚动轴承的物料搬运和/或建筑机械，例如起重机或塔式缆索挖掘机。根据本发明提出，在滚动圈的不同的角度扇区中设置彼此不同的滚道修正部和/或滚道修正部仅设置在滚动圈的圆周的一小部分中。
