(1) In order to make a gap in the radial direction between the bearing retainer and the bearing ring is set larger than the eccentric amount of the internal structure has been improved;
(2) the use of FEM analysis, by the shape and thickness were optimized to improve the strength of the holder;
(3) In order to prevent reduce surface damage caused by lubricating oil in the bearing ring in the design of the guide groove.
