Large Roller Thrust Bearings

Thrust bearings consist of inner and outer rings, inner and outer tracks, and balls. A row of spherical bearings revolves around the circular track. In a thrust ball bearing, the pressure from the load is transmitted from the outer track to the balls and from the balls to the inner track. In effect, the small balls located in the rings of the bearing "bear" the weight of the load, permitting the machine to run smoothly.
