Summary:

High operating life deep groove ball bearing: optimized geometryreduces friction, energy consumption and noise50 percent less noise and 35 percent less friction - Thesignificant performance increase offered by this new bearing typeis primarily attributable to optimized osculation between therolling elements and ring raceways. Osculation between the ballsand rings has been optimized in order to minimize friction. Theimproved surface structures of the raceways and balls reduce noisedevelopment by 50 percent. In combination with improved surfacequality, the design measures reduce friction by up to 35 percentcompared with the previous deep groove ball bearing.Other improvements include more effective seals and a rivetedsteel cage. The innovative HRS seal ensures maximum reliability.Its redesigned lip geometry is optimally adjusted to the recess onthe bearing inner ring. In this way, the seal offers more effectiveprotection against loss or contamination of grease. This results inlonger grease life and increases the life of the entire bearing.The improved guidance of the rolling elements also contributes tohigher performance of the new deep groove ball bearing. The newriveted steel cage offers higher rigidity and is therefore alsosuited for higher speeds.Altogether the design modifications result in higher efficiencyas well as higher achievable speeds and reduced noise. The benefitsare considerable increases in bearing life and performance with anoticeable reduction in energy consumption. This new deep grooveball bearing operates more quietly and efficiently, it is morereliable and offers better performance than its predecessor
