Webbearings lives, using the most basic methods of calculation, is that an L-10 life target is an objective guide and nothing more. How do bearings fail? If using one set of bearings gives a minimum value of L-10 = 166,000 hrs, and another bearing set gives a minimum value of L-10 = 200,000 hrs, both designs meet the specification. WebFor a single bearing, L 10 also refers to the life associated with 90% reliability. The life which 50% of the group of bearings will meet or exceed (median life, or L 50) is usually no greater than five times the rating life (refer to the table under Life Adjustment Factors).
