(1)
Maximum shaft or housing fillet radius that bearing corners will clear.
(2)
These factors apply for both inch and metric calculations. See engineering section for instructions on use.
(3)
Geometry constant for Lubrication Life Factor a 31 is found in the Bearing Ratings section of the Engineering Manual (order no. 10424).
(4)
See thermal speed ratings in the Engineering Manual (order no. 10424).
Note: Where EJ and EM/EMB have different load ratings, the more conservative one was taken to use for both assemblies.
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.
