ABSTRACT:
A bearing assembly includes a double-row cylindrical roller bearing having no seals and having a grease sealed in its internal space. A double-row angular ball bearing having seals is provided in juxtaposition with one end face of the double-row cylindrical roller bearing. During run-in, part of the grease sealed in the double-row cylindrical roller bearing adheres to the outer surface of one of the seals of the angular ball bearing that faces the internal space of the cylindrical roller bearing. This increases the initial amount of grease sealed in the internal space of the cylindrical roller bearing, thereby prolonging its life.
