This racing skate player dedicated bearing utilizes nano-scale titanium treatment technique for inner ring, outer ring and steel ball to enhance hardness on the surface of the product for the bearing to be more wear resistant under high speed rotation and achieve longer service life. The pores on inner ring, outer ring and steel ball surfaces of the bearing can be filled up through the nano-scale titanium treatment technique for the grooves o the inner and outer rings and the surface on the steel ball to be smoother. In conjunction with the assembly technique of the company, the bearing would not generate deflection and shake under high speed rotation, such that the rotation is smoother and easier. This product is researched and developed dedicated to racing competition by the company. There have been surprising performances in several international races. It is the best tool to aid players in striving for good performance.
