Double row deep groove ball bearings

deep groove ball bearings must be sub-jected to additional radial load. Axial load carrying capacity If double row deep groove ball bearings are subjected to a purely axial load, this axial load should generally not exceed the value of 0,5 C0. Excessive axial loads can lead to a substantial reduction in bearing life. Equivalent dynamic bearing load

ENT SKF NEW TOOL FOR ESTIMATING GREASE LIFE IN nt

In a sealed deep groove ball bearing operating at n x d m=300,000 and 55°C, a grease with GPF=1 is the best solution, giving L 10=30,000 hours. For GPF=2 the estimated life is the same, whereas a grease with GPF=4 is not recommended, due to a shorter life. In a shielded 6302-2Z deep groove ball bearing operating at 15,000
