Abstract: 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.

Abstract: A cage for a ball bearing comprising a body of generally annular shape and clamps, the body comprising a heel of substantially annular shape and a substantially axial portion being connected to the heel and wherein recesses are arranged for the balls, the substantially axial portion supporting said clamps on the side axially opposite to the heel, the cage comprising an axial partition placed between the recesses and extending axially from the end of the heel opposite to the clamps toward the clamps while radially delimiting external free spaces and internal free spaces situated radially on either side of said partition.

Abstract: 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.

Abstract: 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.

Abstract: A cage 4 for a ball bearing comprising a body 5 of generally annular shape and clamps 6, the body 5 comprising a heel 7 of substantially annular shape and a substantially axial portion 8 being connected to the heel 7 and wherein recesses 9 are arranged for the balls 3, the substantially axial portion 8 supporting said clamps 6 on the side axially opposite to the heel 7, the cage 4 comprising an axial partition 14 placed between the recesses 9 and extending axially from the end of the heel 7 opposite to the clamps 6 toward the clamps 6 while radially delimiting external free spaces 16 and internal free spaces 15 situated radially on either side of said partition 14.

Abstract: A rolling bearing device comprising two races 10, 11 able to rotate relative to one another and at least one seal 13 attached to one of the races and provided with an active portion 16 designed to interact with a sensor element to detect a parameter of rotation of the active portion, characterized in that it comprises, at least on one side of the rolling bearing, a groove 20 made in the outer race 10 and a groove 21 made in the inner race 11, said grooves being substantially coplanar, the seal 13 being mounted in one of the grooves of one of the races and interacting with at least a portion of the other groove of the other race in order to provide a dynamic seal.
