WebJun 13, 2012 · Bearing fluting resulting from dV/dt of the source voltage is not as likely on medium-voltage 50-Hz supplies as 60-Hz supplies because 50-Hz produces a lower value of dV/dt. Somewhere in my literature collection there is a reference to dV/dt causing bearing fluting on medium voltage 60-Hz supply back in the 1920 era. WebReducing bearing failure 9,5 % of all bearings fail because of operating conditions and need to be replaced before the applications machine life is over. By selecting the right bearing for the right application you can reduce unnecessary downtime, production loss, costs and damage. How to select the right bearing for your business
