A multi-row bearing assembly includes first and second rolling-element bearings having first and second bearing rings and first and second rows of rolling elements therebetween, respectively, each ring having exactly one guide flange. An intermediate space exists between the first and second rows of rolling elements, and a first side of each row of rolling elements faces the intermediate space and a second side of each row of the rolling elements is remote from the intermediate space. The guide flanges of the first and third bearing rings guide the first sides of the rolling elements, and the guide flanges of the second and fourth bearing rings guide the second sides of the rolling elements.

Bearing assembly

A cylindrical roller bearing includes an outer bearing ring, an inner bearing ring and cylindrical rollers located between the outer and inner bearing rings. One of the rings has side rims forming an axial stop for the cylindrical rollers. The bearing ring on which the side rims are not provided is formed with at least one groove outside the axial extension of the cylindrical rollers. A ring of spring-elastic material is positioned in the groove to form an axial stop for the cylindrical rollers. The periphery of the ring has no interruptions. To improve the running behavior of the cylindrical roller bearing, the ring possesses a V-shaped cross-section with two legs.
