A bearing is to be engaged between two or more machine elements, and includes an endless ball chain, and two offset rows of balls engaged in the endless ball chain, for forming an endless planer structure to resist the forces transmitted between the machine elements. The endless ball chain includes a number of spacers disposed between the balls and each having one or more notches for increasing a deformability of the spacers, and has two side flanges and an intermediate flap. The spacers are solidly formed and disposed between the side flanges and the intermediate flap.
