The ball bearing assembly comprises a body portion having one or more recessed sides, and an elongated opening in the body portion extending through the sides. An elongated inner race plate having arcuate ends extends through the opening with at least one side portion of the plate extending into a complementary recess to form an endless inner surface of a ball bearing track. The smooth uninterrupted outer surface of each recess has a straight portion and integral arcuate end portions forming a major portion of the outer surface of the endless ball bearing track. The recesses and outer surface terminate at a flat surface of the body portion, which faces and is spaced from a bearing surface of one of the objects. The bearing surface forms a minor portion of the outer surface of the endless ball bearing track. A cover plate is provided over the recessed side or sides of the body portion for holding the ball bearings in the endless ball bearing track or tracks.
