Why do bearin

3、gs fail?Around 36% of premature bearing failures are caused by inadequate lubrication. Add to this, the bearing failures caused by a contaminated lubricant supply and the percentage of lubrication-related bearing failures can jump up to 50%.16% Poor fitting36% Poor lubrication14% Contamination34% Fa
