Abstract: A deep groove ball bearing providing an inner ring, an outer ring and a plurality of balls being arranged between the inner ring and the outer ring. The inner ring and the outer ring each include a raceway for the plurality of balls. Each raceway encompasses the plurality of balls symmetrically. The deep groove ball bearing is lubricated by a lubricant being arranged on each axial side of the plurality of balls. The raceways are offset in the same axial direction from the axial center of the inner ring and the outer ring such that the raceways are offset to the axial side of the deep groove ball bearing where the shear rate acting on the lubricant is higher than on the other axial side of the deep groove ball bearing.

Abstract: A rolling bearing assembly includes an inner ring, an outer ring, at least one row of rolling elements disposed between raceways provided on the inner and outer rings, and an annular housing having at least one of the rings is arranged. The one ring includes two half ring parts, each half ring part having a radial portion and an inner and an outer axial cylindrical portions extending from the radial portion towards the outside. The inner axial cylindrical portion extend from the radial portion by a toroidal portion defining the raceway, each of the two half ring parts, defining with the annular housing, a closed space. A closed space or spaces can store lubricant and a passageway through at least one half ring part enables lubricant to pass from the closed space to the raceways. A magnetic and/or an electronic element is mounted inside at least one closed space.

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.
