  • Method for lubricating a rolling element bearing
    Patent number: 9964150
    Abstract: A method for lubricating a rolling element bearing, the method comprising a step of providing a bearing cage for retaining rolling elements when the bearing cage is in use, the bearing cage having at least one first ring structure to which at least one first cage bar is connected. The at least one first cage bar is constructed so that a diameter of the bearing cage is largest at one of a point or a region along the length of the at least one first cage bar so as to improve lubricant flow towards the rotational center of rolling elements when the bearing cage is in use.

  • Bearing cage and rolling element bearing
    Patent number: 9394943
    Abstract: A bearing cage for retaining rolling elements of a rolling element bearing, the bearing cage having at least one first ring structure to which at least one first cage bar is connected. The at least one first cage bar comprises a side surface that is arranged to extend along an outer surface of a rolling element when the bearing cage is in use, whereby the side surface comprises a radially outer edge and a radially inner edge. The distance between the radially outer edges of two adjacent cage bars between which a rolling element is located when the bearing cage is in use is greater than the distance between two adjacent radially inner edges of the two adjacent cage bars.
