MOUNTED BALL BEARINGSMAXIMIZE USEFUL BEARING LIFE!DIFFERENTIATED LUBRICATIONAND SEALING SYSTEMS.Ball Bearing RatingsMost mounted bearings operate in conditions that challengetheir sealing and lubrication systems. Sealmaster Gold ballbearings have a reputation for increasing application up-time.The unique features described in this shaded section eachcontribute to better sealing and improved lubricationeffectiveness.L-10 life is the theoretical number ofhours that 90% of bearings shouldlast based on a set of criteriaestablished in 1990 by AFBMA (nowknown as ABMA). The formula isbased on four design and calculatespredicted life based on load and shaftspeed.L-10 Calculation Criteria1. Ball Diameter (D)2. Ball Path Pitch Diameter (P)3. Number of Balls4.
