Abstract: A bearing and bearing system includes a raceway with a first and a second radial flange, a cylindrical cage with openings placed between the first flange and the second flange, and rolling elements disposed in at least some of the openings. The cage is cut by a radial plane forming first and second circumferential edges so that in a first dynamic condition the cage has a first diameter and in a second dynamic condition the cage has a second diameter.

Abstract: A cage for rolling elements of a radial roller bearing is provided having first and second axial flanges spaced from each other by cage bars that extend therebetween that form a plurality of roller pockets. Retention scallops that extend axially inwardly are defined in each of the first and second axial flanges, generally centered about the cage bars, and the cage bars are located radially inwardly of a pitch circle of the rolling elements. The retention scallops extend axially inwardly at a position radially outward from the pitch circle to a position where portions of each of the retention scallops axially overlap end portions of adjacent rolling elements. A method of forming the cage and cage-roller assembly are also provided.

Abstract: A method for manufacturing a bearing ring is provided. The method includes punching out a blank from sheet metal. A radially extending groove is formed in the blank. The blank is stamped in a cup-shaped die which creates an axially extending side wall and a bottom wall, with a first undercut being formed by the radially extending groove located at a juncture between the side wall and the bottom wall at a first axial end portion of the bearing ring. A second axial end portion of the side wall is thinned. The second axial end portion is then bent creating a flange with a second undercut located at a juncture between the flange and the side wall.

Abstract: A shaft seal includes a body portion and a radially protruding lip portion. The body portion has a radial wall with at least one radial groove. The lip portion is integrally formed with the body portion and deflectable for sealing engagement with a shaft. In an example embodiment, the seal is a single piece manufactured by injection molding. In an example embodiment, the seal includes nylon or carbon filled polyamide 46.

Abstract: 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.

Abstract: 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.

Abstract: A tandem roller bearing having circumferential inner and outer races each having first and second contact surfaces with convex profiles is provided. Rolling elements are arranged between the inner and outer races, each of the rolling elements having a concave profile corresponding to the convex profiles of a respective pairing of the first contact surfaces of the inner and outer races or of the second contact surfaces of the inner and outer races.

Abstract: 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.
