An assembly for use in a wellbore can include a drill string having an outer housing and a thrust bearing sleeve positioned within the outer housing of the drill string. The assembly can also include a stationary thrust bearing positioned within the thrust bearing sleeve and coaxially around a mandrel extending through a longitudinal length of the thrust bearing sleeve. The assembly can further include an interlocking component including a first end coupled to the stationary thrust bearing and a second end positioned in a recessed portion of a housing of the drill string for preventing the stationary thrust bearing from rotating about a central axis of the mandrel, and for allowing the stationary thrust bearing to rotate about one or more axes perpendicular to the central axis. The assembly can include a flexible member for opposing a rotational force applied to the stationary thrust bearing by another thrust bearing.
