摘要： The bearing cage has a first flange, a second flange, and a plurality of cage bars extending between the first flange and the second flange so as to form and define outer boundaries for a plurality of pockets. The first flange and the second flange are each bent inward toward the pocket and then extend parallel in a vertical direction, forming a contact surfaces. The contact surfaces are in contact at each end of the rollers arranged in the pocket. The contact surfaces of the bearing cage present a large contact area between the ends of the rollers and the ends of the pockets where there is a lubricant film. Also, the surface of the contact surfaces is smooth.

摘要： The bearing cage with high speed features has a pocket with a first flange and a second flange which defines the outer boundaries of the pocket. The first flange and the second flange each have a plurality of inwardly directed protrusions facing each other. The protrusions are contactable at each end of rollers, which are arranged in the bearing cage. The protrusions can be dome shaped, creating a small area of contact between the rollers and protrusions. The point of contact between the rollers and the protrusions is at the center of the rollers, which reduces the relative speed between the ends of the pockets and the rollers.

摘要： A cage for a radial roller bearing of limited width availability, which has a first flange, a second flange spaced from the first flange, and cage bars that extend between the first flange and the second flange so as to form a plurality of roller pockets. The cage bars, together with the first flange and the second flange form an S-shaped or a Z-shaped contour. The cage aids in properly guiding roller elements in bearings of limited widths. The cage prevents rolling elements from overrunning or under running the cage bar. The cage also provides for proper contact of the rolling elements to push the cage around the radial bearing. Further, the cage allows for inner retention, outer retention, or both inner and outer retention of the rolling elements.

摘要翻译： 一种用于具有有限宽度可用性的径向滚子轴承的保持架，其具有第一凸缘，与第一凸缘间隔开的第二凸缘以及在第一凸缘和第二凸缘之间延伸以形成多个滚筒凹部的保持架。 笼杆与第一凸缘和第二凸缘一起形成S形或Z形轮廓。 保护架有助于在有限宽度的轴承中正确引导滚子元件。 笼子可以防止滚动元件超驰或运行笼子杆。 保持架还提供滚动元件的正确接触，以将保持架推向径向轴承。 此外，保持架允许滚动元件的内部保持，外部保持或内部和外部保持。
