摘要： The invention concerns a bearing assembly comprising an inner ring, an outer ring and rolling elements, the inner ring and outer ring being rotatably coupled by means of the rolling elements. The rolling elements are disposed on opposing raceways within a bearing cavity and are retained in a cage. The bearing is provided with a lubricant and further comprises at least one sealing element, mounted in an annular gap between the inner and outer ring. To prevent the lubricant adhering to predetermined surfaces within the bearing cavity which do not require lubrication, at least one of these predetermined surfaces is provided with an oleophobic coating. One advantage of the invention is that the lubricant ages less quickly, leading to improved bearing service life.

摘要： Cage 4 for a ball bearing, comprising an annular heel 7 and a substantially axial portion 8 provided with claws 11 defining pockets 9 for balls and connected to the heel 7, the substantially axial portion 8 extending axially over a part of the pockets 9. The substantially axial portion 8 has an outside diameter smaller than the outside diameter of the heel 7, the outside diameter of the substantially axial portion being somewhere between the pitch circle diameter of the cage reduced by half the radial thickness of the heel and the pitch circle diameter of the cage increased by half the radial thickness of the heel.

摘要： Retaining cage for balls of a rolling bearing, comprising an annular shoulder (16) extended axially by projecting portions (18) defining between them sockets (15) for the balls, emerging radially on either side of the cage. The cage was made from a metal and the surface of each socket (15) is designed to cooperate with one of the balls and is defined by an imaginary cylinder with an axis oriented radially and cut by the plane axially delimiting the cage on the side opposite the shoulder (16) so as to form an axial opening of the socket, the width of this opening being smaller than the diameter of the said imaginary cylinder.
