Abstract: In a tapered roller bearing in which a segment holder divided into a plurality of segments in a circumference direction is used in an inner ring assembly, which is incorporated into an outer ring, guide claws are provided on an outer-diameter side of adjacent columnar portions of each pocket of a holder to allow the tapered rollers to be inserted into the pockets from an inner-diameter side of the segments. An engaging portion is provided on a large-diameter-side lateral-surface of a large-diameter-side arc-shaped portion of the segment. A connecting member, which is to be wound around on a large-diameter side of the segments arranged in a ring shape, is made to pass through the engaging portion, and ends of the connecting member are removably connected together by a fastening member, so that adjacent segments are butted together and fixed.

Abstract: An axial bearing assembly is provided having a first washer forming a first raceway and including a radially inner retention flange, and a second washer forming a second raceway axially spaced apart from the first raceway, with the second washer including a radially outer retention flange. A cage including a radially inner rim, a radially outer rim, and a plurality of segments extending between the radially inner and outer rims defining a plurality of rolling element pockets is located between the first and second raceways. Rolling elements are located in at least some of the pockets. The radially outer rim of the cage includes a circumferentially extending groove on a radially outer surface. Outer retention tabs extend from the radially outer retention flange into the circumferentially extending groove.

Abstract: Provided is a method of manufacturing a resin retainer having two annular sections. A fixed-side cavity forming mold has a first axial mold surface that is in contact with an axial end surface of a first annular section of the annular sections of a resin retainer having two annular sections, and a first protruding portion protruding from the first axial mold surface. A movable-side cavity forming mold has a second axial mold surface that is in contact with an axial end surface of a second annular section of the annular sections of the resin retainer, and a second protruding portion protruding from the second axial mold surface. A slide core sliding step is performed in which slide cores are slid toward an outer diameter and pocket-forming protruding portions of the slide cores are extracted from a pocket of the retainer, and then a mold opening step is performed in which the movable-side cavity forming mold is opened relative to the fixed-side cavity forming mold.

Abstract: A rolling bearing cage includes axially spaced side rings, cage webs connecting the side rings, cage pockets, and first and second cage ends. The cage webs have rolling element guides projecting radially inwards and the cage pockets are formed between the rolling element guides. The first cage end has a closing element formed by an axial groove at a radial web surface of a cage web that is reinforced relative to the other cage webs and delimits a penultimate cage pocket. The second cage end has a closing element formed by a partial cage web connecting the end portions at the second cage end to one another. The partial cage web is arranged to hook into the axial groove to form a cage lock that secures the second cage end to the first cage end against unintentional loosening in a peripheral direction and in both radial directions.

Abstract: A bearing module that supports adjacent ends of coaxial shafts, includes an outer ring having first and second axially adjacent raceways and first and second flanges located at the respective ends. A first group of rolling elements rolls on the first raceway, and a second group of rolling elements rolls on the second raceway. A first cage retains the first group of rolling elements circumferentially spaced apart from one another, and a second cage retains the second group of rolling elements. An axial bearing is retained axially between the first and second groups of rolling elements, and has axial bearing rolling elements that are configured for rolling contact with (a) facing axial side raceways on first and second inner rings supported respectively on the first and second groups of rolling elements, (b) the adjacent ends of the two coaxial shafts, or (c) integral washers of the axial bearing.

Abstract: A bearing cage assembly comprises multi-group rollers (2), each group has multiple rollers, and each roller is a barrel roller, multiple rollers are stacked together to form a group of rollers, and the end surfaces of each two adjacent rollers contact with each other. Multiple groups of pockets (11) are formed in the cage, and each group of pockets has multiple pockets. The pockets in any group are distributed along the circumference direction of the said cage, and a group of rollers is disposed in each pocket. Multi-group rollers can roll in circumferential direction of the cage. During the rolling process, a great number of contact points are distributed on the raceways, thus the load capacity of the bearing is improved, the friction resistance is low, suitable for the fields where high speed operation is necessary. A planar thrust bearing, a radial bearing and a conical radial-thrust bearing are provided.
