Flange bearings mainly bear radial loads, but also bear radial and axial loads at the same time. But for the life of flange bearings are not very well understood, the following three measures to extend the life of bearings:
(1) In order to make the clearance between the bearing retainer and the bearing ring in the direction of radius larger than the eccentricity, the internal structure is improved;
(2) The strength of the retainer is improved by optimizing the shape and plate thickness through FEM analysis;
(3) In order to prevent the surface damage caused by the reduction of lubricating oil, the guide groove is designed in the bearing ring.
