A yo-yo with an axle having two side-by-side bearings constituting a double bearing that enhances yo-yo performance characteristics by improving balance and reducing unwanted effects such as wobble, tilting, twisting, vibration, and string friction. Each bearing having an outer ring, an inner ring, and an array of balls trapped in tracks between the two rings. The outer rings of the bearings may be beveled to form a groove to enhance stability and centering of a string. Alternatively, the bearings may be covered with a bridge that has a straight outer surface or has an outer surface with a groove that could take several shapes. The bridge may have an internal ridge that acts as a centering mechanism for the bearing and bridge assembly. The inner and outer rings of the bearings may be independent or shared, and the rings of one bearing may overlap the rings of the other bearing. The inner rings of the bearings may be extended outward to provide spacing between bearing parts and yo-yo side walls.
