A diabolo with a bearing is a type of diabolo where the axle is equipped with ball bearings, allowing the diabolo to spin longer and faster than a fixed axle diabolo. The ball bearings reduce the friction between the axle and the string, meaning the diabolo retains its rotation for a longer time without losing speed. This makes it easier to perform tricks, as the diabolo maintains its speed and momentum for a longer period, giving the player more time to execute complex movements and tricks.

The advantage of a bearing diabolo is that it is easier to control in terms of rotational speed, requiring less physical effort to maintain its spin. This makes it an ideal choice for both beginners, who want an easier start, and experienced players, who wish to perform more complex and precise tricks.
