The life expectancy is discussed of freight car roller bearings which have seen extensive service. The meanings of the terms life expectancy and B-10 life as defined by the AAR are given. A typical bearing life expectancy curve is shown. A group of used bearings which are carefully inspected according to manufacturer's recommendtions should perform with reliability very nearly the same as new bearings. For maximum economy, such bearings should be reused based upon normal inspection and maintenance practices.
