It ‘epends upon the kind of machine tool, whether iti. special purpose machine working under constant working conditions oF luniversal machine tool where the machining conditions, are regularly varying, It also depends upon the position in which the bearing is used and the ease with which it can be replaced. The life ‘expectancy of the bearing may coincide withthe life expectancy of themachine or be only apart ot for example itmay be equal tothe ‘overhauling period decided by experience. However. the li expectancy of a bearing used in machine tol working continuously for 8 hours a day at constant load and speed is choosen between LIFE CALCULATION OF neARINGS 39 20,000 to 30,000 hours. A value between 50,000 to 60,000 hours is selected for machines working continuously all the 24 hours of the ay. Very often the bearings used in machine tols are subjected to varying loads and work at varying speeds. In these circumstances, it is necessary to make an estimate of equivalent required life which will ultimately give the bearing a life expectancy as chosen above. For this it s necessary to estimate from previous experience with such machines the values of different loads that wil act and periods asa percentage of total time these loads wil act.
