NTN EA surface technology extends the life expectancy of bearings

A standard bearing of identical type and size will have the L10 fatigue life of around double its equivalent manufactured 50 years ago, and this is reflected in the increased dynamic load ratings published by bearing makers. This is because contemporary rolling bearings produced by reputable manufacturers are made from clean alloy steels with applied processing technologies which result in a much lower incidence of premature surface contact fatigue.
