Abstract

A flexible bearing including spacers is provided. The flexible bearing includes: an outer race including a rolling groove; an inner race arranged in the outer race and including a rolling trough corresponding the rolling groove to collectively define a loading passage; rolling elements arranged in the loading passage; and spacers each including a retention section for receiving and retaining the rolling elements. Two adjacent ones of the spacers are in contact engagement with each other with end faces thereof and the two end faces are respectively a concave surface and a convex surface. The concave surface and the convex surface of the spacers are allowed to undergo relative sliding so as to allow the spacers to adjust, with respect to each other, an angular position thereof during an operation of the flexible bearing in order to prevent the spacers from interfering with the outer race or the inner race.
