摘要： The invention relates to a bearing cage including a bearing cage main body made of a polymer material and having pockets for receiving at least one row of rolling elements of a bearing. The cage is provided with a passive resonant circuit including an antenna coil attached to the cage main body. It is proposed that the antenna coil is formed as a conductive layer directly attached to the cage material of the bearing cage main body and is designed so as to have a breaking point less than or equal to a breaking point of the cage material. Thus, a rupture in the cage main body ruptures the antenna coil, changing the resonance behaviour of the passive resonant circuit.

摘要： A bearing cage assembly (100) comprises a plurality of discrete bridge elements (206) disposed between adjacent rolling elements (112) and coupled between first and second axially spaced cage support wire rings (102, 104) which are appropriately tensioned. Spacers (110) are disposed between adjacent bridge elements and engage the bridge elements in a piloted engagement. The bridge elements maintain a separation between rolling elements, retain the rolling elements within the bearing assembly, and function as a lubrication reservoir for grease lubricated bearings. Profiled surfaces on the bridge elements position the bearing cage assembly on at least one axial end of the rolling elements.

摘要： An object of the present invention is to prevent breakup of segments which constitute a split type retainer for a tapered roller bearing, when the tapered roller bearing is being mounted on target equipment, thereby improving operability in the mounting process. A segment for a tapered roller bearing is provided with a predetermined number of posts between a small-diameter-side end fringe which constitutes a small-diameter-side circumferential edge of a split type retainer and a large-diameter-side end fringe which constitutes a large-diameter-side circumferential edge thereof. Pockets are formed between the posts. At least the large-diameter-side end fringe, out of the small-diameter-side end fringe and the large-diameter-side end fringe, is provided with a large-diameter-side engagement piece. When the bearing is mounted, the large-diameter-side engagement piece is engaged with the large-diameter engagement member fitted and fixed onto the bearing's inner ring, whereby the segment is prevented from breaking up.
