Dynamic bearing load คือ
WebWhen specifying the average lifespan of a bearing, I suggest using the American Bearing Manufacturers Association’s (ABMA) preferred method, calculating for L10 life. In the simplest terms, L10 life is calculating, with 90% reliability, how many hours a bearing will last under a given load and speed. There is a 10% probability that at the ... WebWhen F a /F r ≦e for single-row radial bearings, it is taken that X=1, and Y=0. Hence, the dynamic equivalent load rating is P r ＝F r. Values of e, which designates the limit of F a /F r, are listed in the bearing …
