6. Load rating and rating life | Engineering Information | …

This section provides an overview of the "rating life" and modified rating life of "single-row deep groove ball bearings" specified in JIS B 1518. Rating life is the predicted life based on the basic dynamic radial load rating. Modified life is the life rating in which 90% or greater reliability, fatigue limit load, lubricant contamination, and

The Basics of Bearing Life - NES Bearing Co., Inc.

The Basics of Bearing Life. An alarming amount of bearing failures are due to debris that has found its way into the bearing from improper care before, during, or after assely. Contamination can interfere with the operation of the bearing by eventually working its way into the lubriion. Once the lubriion is affected, a gradual wearing
