» Bearings for high speed operations

By reducing the diameter of a ball to 75 % (a real case) the mass will be reduced to 42 %. Example. Bearing 7014 CD having a ball diameter of 12,7 mm is running at 15,000 r/min. The centrifugal load from each ball is then 174 N. If the ball diameter is reduced to 7,938 mm (62.5 %) the centrifugal load from each ball is 79 N, a reduction to 45 %.
