These factors apply for both inch and metric calculations. See engineering section for instructions on use.<br />
(3)<br />
Geometry constant for Lubrication Life Factor a 31 is found in the Bearing Ratings section of the Engineering Manual (order no. 10424).<br />
(4)<br />
See thermal speed ratings in the Engineering Manual (order no. 10424).<br />
Note: Where EJ and EM/EMB have different load ratings, the more conservative one was taken to use for both assemblies.<br />
NOTE: Tolerance and shaft diameters are shown in tables E-2 and E-3 on pages E-5 and E-6 as variances from nominal bearing bore.<br />
