Cage with storage space for a lubricant

A roller bearing comprising a cage with a storage space for a lubricant having an axis of rotation along an axial axis of said cage, said cage comprising:

• two chambers configured to house two rotating elements, each of the two chambers having an opening on a first side of the cage, a line perpendicular to a surface defining the opening being substantially parallel to the axis of rotation of the cage;
• and
• at least one storage space for lubricant between the two chambers, said storage space comprising an inner wall, two lateral walls, an outer wall and at least one outlet for the lubricant, wherein the at least one outlet is oriented substantially parallel to the axis of rotation and has an opening on the same side of the cage as the openings of the two chambers, and wherein a first closed conduit is provided from the at least one storage space to one of the two chambers and a second closed conduit is provided from the a least one storage space to the other of the two chambers.

A cage with a storage space for a lubricant having an axis of rotation along an axial axis of said cage, said cage comprising:

• two chambers configured to house two rotating elements, each of the two chambers having an opening on a first side of the cage, a line perpendicular to a surface defining the opening being substantially parallel to the axis of rotation of the cage;
• and
• at least one substantially closed storage space for lubricant between the two chambers, said storage space comprising an inner wall, two lateral walls, an outer wall, a bottom, an opening, and at least one outlet for the lubricant, wherein the at least one outlet is disposed on the outer wall extending from an edge portion of the outer wall adjacent to the opening toward the bottom, wherein the at least one outlet comprises a slot having a first portion with a first width adjacent to the bottom and a second portion with a second width adjacent to the opening, and wherein the first width is greater than the second width.

A cage with a storage space for a lubricant having an axis of rotation along an axial axis of the cage, the cage comprising:

• a storage space for lubricant between a first chamber configured to house a first rotating element and a second chamber configured to house a second rotating element, the storage space comprising a first lateral wall, a second lateral wall, a first closed conduit having an elongated tubular shape, and a second closed conduit having an elongated tubular shape, wherein an end of the first closed conduit opens into the storage space through the first lateral wall and the other end thereof opens into the first chamber, wherein an end of the second closed conduit opens into the storage space through the second lateral wall and the other end thereof opens into the second chamber, and lubricant from the space is supplied to the first and second chambers via each of the closed conduits.
