Cylindrical roller bearing for left tappet of print cylinder of printing machine, has external and internal rolling paths formed like cylindrical casing or truncated cone casing, so that radial distances of paths to axial side are increased

摘要

The bearing has two ring-like cylindrical roller rows arranged side by side, where the cylindrical rollers (30) of the rows roll at an external rolling path (22) and an internal rolling path (12). The rolling paths are formed like a cylindrical casing or a truncated cone casing such that radial distances of the rolling paths to an axial side are increased. The radial distances correspond to an inclination of two linear slopes with an angle of approximately 1.5 to 4 angular minutes to each other. The rollers of the rows are formed dimensionally similar to each other.
