Thrust-bearing assemblies, and thrust-bearing apparatuses and downhole motors incorporating such thrust-bearing assemblies are disclosed. In one aspect of the present invention, a thrust-bearing assembly is disclosed. The thrust-bearing assembly comprises a seat including a generally spherical surface at least partially defining a recess. A bearing support is positioned within the recess. The bearing support includes a generally spherical surface configured so that the bearing support is capable of movement with the recess of the seat. At least one bearing element may be mounted to the bearing support. The thrust-bearing assembly further includes a motion-limiting structure configured to limit relative movement between the bearing support and the seat. The motion-limiting structure does not extend between the generally spherical surface of the seat and the generally spherical surface of the bearing support.
