摘要： A tapered roller bearing (31a) has a plurality of retainer segments (11a, 11d) each having a pocket to house a tapered roller (34a), and arranged so as to be continuously lined with each other in a circumferential direction between an outer ring (32a) and an inner ring (33a). The retainer segment (11a, 11d) is formed of a resin containing a filler material to lower a thermal linear expansion coefficient. In addition, a clearance (39a) is provided between the first retainer segment (11a) and the last retainer segment (11d) after the plurality of retainer segments (11a, 11d) have been arranged in the circumferential direction without providing any clearance. Here a circumferential range (R) of the clearance (39a) is larger than 0.075% of a circumference of a circle passing through a center of the retainer segment (11a, 11d) and smaller than 0.12% thereof at room temperature.

摘要： A roller bearing includes an inner ring having an inner-ring raceway surface on an outer periphery of the inner ring, an outer ring arranged concentric with and peripherally outside the inner ring, and having, on an inner periphery of the outer ring, an outer-ring raceway surface that faces the inner-ring raceway surface, a plurality of rollers interposed between the inner-ring raceway surface and the outer-ring raceway surface in a rollable manner, and a cage that holds the rollers at predetermined intervals along a circumferential direction. Opposite end portions of the outer-ring raceway surface in an axial direction serve as guide surfaces or which rotation of the cage is guided. Or an outer periphery of the cage, slidable contact surfaces are formed which slidably contact the guide surfaces and which are arranged to thee the respective guide surfaces across a labyrinth clearance.

摘要： A cage for a rolling bearing having a film, formed on a surface thereof, which wears little over a long period of time from an initial stage of sliding contact between the film and rolling elements as well as other members and does not peel off the surface of a base material of the cage or dissolve in lubricating oil containing a sulfur-based additive and a rolling bearing having the cage. A cage (2) retains needle rollers (3) which are rolling elements of a needle rolling bearing (1). Of an entire outer surface of the cage (2), a tin alloy film consisting of tin and a metal other than the tin is formed on at least a sliding-contact surface of the cage (2) to be subjected to sliding contact with the needle rollers (3) and a sliding-contact surface thereof to be subjected to sliding contact with other members.

摘要： Surface indentation and oil film shortage on rollers is prevented and longer service life of a roller bearing is achieved, by preventing wear debris from being caught and accumulated in pockets of a holder of the roller bearing. Positions and dimensional relations of the diameters of inner and outer ring raceways, the inner and outer diameters of the holder, and inner and outer protrusions which are provided to pillar parts of the holder to prevent the rollers from coming off are defined such that the inner and outer protrusions of the pillar parts always do not come into contact with the outer circumferential surfaces of the rollers in the state where the rollers and the holder are incorporated between inner and outer members. As a result, lubricant oil is smoothly circulated in gaps formed between the outer circumferential surfaces of the rollers and the pillar parts of the holder.

摘要： A rolling-element bearing includes an inner ring made of steel and having an inner-ring raceway, an outer ring having an outer ring raceway, and ceramic rolling elements which roll on the inner-ring raceway and on the outer-ring raceway. The inner ring has been subjected to a heat treatment to harden it. The heat treatment is concluded with the performance of a final heat-treatment step at a predetermined temperature. In the inner ring, compressive residual stresses are formed in an outer layer by cold working in the region of the inner-ring raceway. The inner ring also has been subjected to a bluing treatment.

摘要： A tapered roller bearing (1) with two coaxial bearing rings (2, 3) and a multiplicity of tapered rollers (4) which are arranged between the bearing rings (2, 3), are guided in a cage (10, 11, 12) and roll on raceways (7, 8) on the bearing rings (2, 3), with a rim (9) at the large diameter of the inner bearing ring (3), wherein the cage (10, 11, 12) is formed of side rings (10, 11) and webs (12) which connect them, with the formation of pockets (13) for the tapered rollers (4), and elastic projections (14) are arranged on one side ring (10), which projections (14) interact with the rim (9) and prestress the cage (10, 11, 12) with the tapered rollers (4) axially against the rim (9). In order to achieve play-free and constraint-free setting of the tapered rollers against the guide rim and to make it possible to apply or introduce active or passive transmission elements to the individual components of the tapered roller bearing, fewer projections (14) than pockets (13) are arranged on the side ring (10) which is close to the rim, preferably only in the region of every second pocket (13) in the case of an even number of pockets (13). An active or passive transmission element (20, 21, 22) is arranged on the rotating bearing ring (2, 3) and/or on the cage (10, 11, 12) and/or on at least one of the tapered rollers (4), and at least one sensor is arranged on a stationary component, which sensor interacts with said stationary component for monitoring the state of the kinematic conditions of the bearing (1) during operation.
