A bearing cage and a bearing are provided. The invention relates to the technical field of bearing, by designing a bearing cage with a conical arc structure at the bottom between pockets and a groovestructure at the bottom, the technical problem of reducing the service life of the bearing due to factors such as instability of the cage during high-speed operation, uneven distribution of internal lubricating grease, instability of the pocket shape and the like existing in the prior art is solved. The bearing cage includes a cage body provided with a plurality of pocket holes and a groove structure at the bottom of the cage; the bottom between adjacent pockets is provided with a conical arc structure. The bearing cage is used for the bearing, can keep the stable running of the bearing cage.The grease is distributed uniformly, the wall thickness between the arc surface at the bottom of the outer diameter and the inner surface of the pocket is consistent (close) with the wall thickness between the arc surface at t
