Abstract
An axial-radial roller-bearing assembly for mounting rotor blades on a wind-power plant has a first bearing ring forming a race and centered on a bearing axis and a second bearing ring forming another race coaxial to the race formed by the first bearing ring. A radial roller bearing with rollers as rolling elements is between the first and second bearing rings. First, second, third, and fourth axial roller bearings have rollers serving as rolling elements between the first and second bearing rings and axially spaced from one another. The radial roller bearing is axially between the second and third axial roller bearings.
