Consequently, it is clarified that the mean value of the retainer revolution component calculated *in* all locations of *balls* decreased *with* increasing number of *balls* *in* *a* rolling bearing. ...
The nonrepetitive runout (NRRO) value of retainer revolution is caused mainly by the diameter differences of *balls* mounted *in* *a* bearing. ...
, (r 0 , *a* *rn* , φ *rn* ), (R 0 , *a* *Rn* , φ *Rn* ) and (r bk0 , *a* bkn , φ bkn ) are coefficients *in* the Fourier series expansion. ...
