摘要： PURPOSE:To make the number of service pieces of rolling elements in each row be equal in case of a single row ball bearing as well as to secure such a constitution as capable of reducing the cost of manufacturing. CONSTITUTION:A double row ball bearing 1 is provided with two sets of inner and outer rings 2, 3 and 4, 5 to be installed adjacently in the axial direction, plural groups of rolling elements 6 to ne interposed between two sets of these inner and outer rings, and a single cage 7 holding these two-row groups of rolling elects 6 at the same time. In brief, these inner and outer rings usable in common with the single ball bearing are formed into two sets, whereby even if a cage for two rows is used, assemble in a state that the number of service pieces of rolling elements at each row is made to be equal to the single ball bearing is made achievable and, what is more, the whole body consisting of separate parts is formed inseparable.

摘要： PURPOSE: To simplify the manufacturing and assembling of a cage by forming axially outward-pointing projections on a cage segments having the pockets to hold the rolling elements, and forming the openings to hold the connecting elements on the projections. CONSTITUTION: The rolling elements 2 are fitted in the cage segments 1a-1d in such manner that they are connected to one another by the cage rings 3, 4. The axially outward-pointing projections 7, 8 are formed at both sides of the cage segments 1a-1d, and these projections 7, 8 comprise the openings 9 to hold the cage rings 3, 4 at both end face sides thereof. When a cage is to be assembled, the cage segments 1a-1d are fitted to the rolling elements 2 and then the cage rings 3, 4 are fitted to the openings 9 of the projections 7, 8 like a snap. The cage segments 1a, 1b are axially alternately directed in the opposite directions, so that the projection 7, or 8 of one of the cage segment 1a and the projection 8 or 7 of the adjacent cage segment are alternately connected by the cage ring 3 or 4 of one side.
