Roller bearing such as a double-row radial spherical roller bearing, has multiple barrel-shaped rolling elements, which are rolled-off in three rows of bearings between two concave running tracks around bearing axis

摘要

The roller bearing (1) has multiple barrel-shaped rolling elements (3,4,5), which are rolled-off in three rows of bearings (6,7,8) between two concave running tracks (9,10,11,12,13,14) around a bearing axis. An axially central bearing row has a symmetrical barrel-shaped rolling element, and the two axially outer bearing rows have asymmetrical barrel-shaped rolling elements. The rolling elements of each bearing row are guided and spaced by a separate cage.
