This is the prized part of Burning Kerberous. The Double Bearing Core contains two bearings (hence its name) and provides very good endurance. The tip is similar to the tip of Metal Change Base (Driger S); when the beyblade is shot at the center, the tip has very high endurance, and when the Beyblade is shot at an angle, the tip moves around in an attack pattern. The Beyblade also switches between attack and endurance during a battle. The bearing case can only hold one other shaft, Wolborg 2's shaft.
AR: Scissor Attacker (Metal Dranzer) WD: Wide Survivor SG: Neo Left SG (Double Bearing Core) SP: Survivor Ring (Dark Series) BB: Customize Bearing Base This combination provides great endurance. The AR, WD, and SP work in unison to spin steal effectively, while the Double Bearing Core provides the endurance.
