Abstract: To provide good cage guidance in a window cage for a preferable flangeless spherical roller bearing in order that the bearing might achieve higher loads, the cage includes two annular axially spaced apart ribs and transverse ribs that extend between the annular ribs and define cage pockets. At least one and preferably two and preferably opposite pockets of the cage are loading pockets. The annular ribs are radially outside the pitch circle of the bearing, but at the loading pockets, those ribs are recessed inward nearly on the pitch circle of the bearing and preferably outward thereof about the thickness of the rib material. The angle between the center of the loading pocket and the adjacent pocket is larger than the angle between the centers of other adjacent pockets to facilitate loading of the loading pockets.

Abstract: In a self-aligning roller bearing providing an outer race, an inner race, a plurality of barrel-shaped rollers, and a pair of cages, guide surfaces formed on outward flange portions of the cages for guiding the barrel-shaped rollers are caused to come closer to ends of the barrel-shaped rollers, so that the barrel-shaped rollers can be guided without fail even if an axial load is received. Therefore, the barrel-shaped rollers are prevented from being skewed, from increasing in torque required for rotating the barrel-shaped rollers, and from seizing up the barrel-shaped rollers.

Abstract: A segmented roller clutch cage is comprised of loose jointed modules that combine good clutch race conformance with easy assembly, as well as allowing for selective module disassembly axial parting motion.Each of a plurality of separately molded elements is joined to the next with identical male and female fasteners that fit together with a simple straight line push, along the cage axis. A slide and rail combination on one end of each module fits into matching grooves on the other end of each module. The grooves are created by undercut, radially opposed beam pairs, the radially outboard one of which is more flexible. A barb on the slide-rail unit is designed to snap or latch past the flexible beam. The slide and rail fit into the grooves with enough clearance to give freely expanding and contracting joints, so that between race conformance is very good. The joints may even be disassembled with a compound radial bending and axial parting motion.

Abstract: A roller-bearing cage prevents bearing rollers from falling out of the cage when the outer ring of the bearing is away from the cage, for example, when the outer ring is removed, the cage is removed or the cage is swung out from the outer ring. The rollers are held in place by holding knobs formed on a radially outwardly directed cage flange located at the axial end of the rollers. The knobs are located radially outwardly of the pitch circle of the rollers, are spaced circumferentially apart sufficient to be out of contact with the rollers when the rollers are in the operating position of the bearing in contact with the outer and inner ring, yet are spaced close enough together that the space between two holding knobs is less than the diameter of the roller lying opposite the knobs. The knobs are formed on a resilient, outwardly directed cage flange which moves resiliently upon the snapping in and out of the rollers in the cage. The knobs may be hemispherical or frustoconically shaped.

Abstract: A needle roller bearing is directed to avoid a possibility that an inner peripheral surface of a bore in a housing may be ground or scraped by an edge defining a peripheral lip region of an opening in an outer race when a needle roller bearing is to be press-fitted into the bore in the housing and also to eliminate the need to adjust the position of a roller retainer while increasing a physical strength of the roller retainer.

A plastic needle separator housing element provides a race and is in axial registration with the frangibly attached needles. A shaft (on which a sprocket of a web feed device or tractor is mounted), upon axial insertion through the member to which the needles are attached, frees the multiple needles from the frangible attachment to the member and ejects the member from the cover leaving the needle bearings captured by the race in the cover.

The roller mechanism includes a plurality of roller members and a plurality of frangible connector links for initially connecting each roller member to an adjacent roller member. The roller members and the connector links are integrally molded together. The cage member includes a circular flange and a plurality of spacer pegs extending perpendicular from the flange in a circular configuration. The pegs are spaced apart from one another and each peg includes a tip having a hollow chamber adapted to receive and store a connector link.

The severed roller members are then free to independently rotate within the cage member.
