High operating life deep groove ball bearing: optimized geometry reduces friction, energy consumption and noise 50 percent less noise and 35 percent less friction - The significant performance increase offered by this new bearing type is primarily attributable to optimized osculation between the rolling elements and ring raceways. Osculation between the balls and rings has been optimized in order to minimize friction. The improved surface structures of the raceways and balls reduce noise development by 50 percent. In combination with improved surface quality, the design measures reduce friction by up to 35 percent compared with the previous deep groove ball bearing. Other improvements include more effective seals and a riveted steel cage. The innovative HRS seal ensures maximum reliability. Its redesigned lip geometry is optimally adjusted to the recess on the bearing inner ring. In this way, the seal offers more effective protection against loss or contamination of grease.
