               ball  to  the  outer  race  and  ultimately  onto  the  bearing  housing.  This
               style  is  not  suitable  for  tilting  moments  such  as  may  result  from  shaft
               misalignment  difficulties.
               With  the  Back  to  Back  arrangement,  the  load  lines  diverge  as  they
               approach  the  bearing  centerline,  and  this  one  can  also  accommodate
               axial loads  in  both  directions.  In  this  arrangement,  it is the  first  bearing
               that  transfers  the  load  from  the  inner  race,  through  the  ball,  to  the
               outer  race.  It is this  arrangement  that  is normally  used  in process  pumps
