A bearing isolator having a simple design and made from low-cost materials but which performs comparably to other higher-cost bearing isolators is described. The bearing isolator generally includes a rotor having a snap fit feature protruding from a radially-oriented flange and a stator having a snap fit feature recess for receiving the snap fit feature to thereby join together the stator and rotor without need for, e.g., a separate unitizing element. Furthermore, the rotor and/or stator can be made from lost cost material, such as a nylon/moly material. In some embodiments, the stator further includes a lip seal biased against the radially-oriented flange of the rotor, which, when combined with the labyrinth passage formed at least in part by the snap fit feature and snap fit feature recess, helps to prevent egress and ingress of lubricant and/or contaminates.

A propeller shaft assembly including a first shaft that presents a plurality of external splines, and a second shaft that has an internal wall which defines an axial bore. The axial bore receives the first shaft and presents a plurality of internal splines that are interleaved with the external splines of the first shaft for providing relative axial movement between the first and second shafts while rotationally fixing the first and second shafts to one another. At least one thrust ring is positioned against the internal wall of the second shaft and surrounds the external splines of the first shaft. The at least one thrust ring has at least one contact portion that is radially deformed in a bending manner against the external splines for causing a radial preload against the external splines. The at least thrust ring extends between a pair of ends that are disposed in spaced relationship with one another to define a gap between the ends.

Provided is a slide bearing of lower cost that is capable of preventing the intrusion of dust, muddy water, etc. and has good sliding performance. In a ring-shaped space (5) formed by assembling an upper case (2) with a lower case, a ring-shaped outer dust seal part (42), which bends with one end (420) contacting the upper case (2) and the other end (421) contacting the lower case, is disposed on the outside of a ring-shaped thrust bearing part (40), and the outer dust seal part (42) is connected to the thrust bearing part (40) by connecting parts (43) that extend radially outward from the outside of the thrust bearing part (40), integrating the two as a dust seal-integrated center plate (4). Disposed between the thrust bearing part (40) and the upper case (2) is a ring-shaped lubrication sheet (6), which has surfaces (62, 63) that slide on the mating surfaces facing same.

Slide-bearing assemblies capable of enabling sliding of a load-carrying implement relative to a load-supporting structure, having first and second load-carrying surfaces, respectively, are disclosed. In one embodiment, the slide-bearing assembly includes substantially nonmetallic first and second elongate bearing elements extending in parallel to support the first load-carrying surface of the load-carrying implement slidably upon the load-supporting structure. One of the bearing elements being composed of multiple elongate pieces each shorter in length than a length of the other of the bearing elements. The slide-bearing assembly additionally includes a post that extends from a surface of each of the multiple elongate pieces, which is a surface that is opposed to the second load-carrying surface, each post is sized to fit in a respective recess of the second load-carrying surface. The slide-bearing assembly further includes at least one coating on the first load-carrying surface made of high-performance thermoplastic material(s).

The present disclosure discloses a sliding bearing comprising a fluorination-treated bonding layer, the sliding bearing comprising a sliding layer, a backing layer and a bonding layer with at least one fluorination-treated surface. The present disclosure further provides a method for preparing said sliding bearing. While maintaining bonding stren gth between sliding layer and backing layer in the sliding bearing, the present disclosure provides a bonding layer of a lower content of fluorine and thereby minimizes the cost of raw materials and influences to the environment.

A ball bearing retainer holds balls disposed between an inner ring and an outer ring, in pockets formed at a plurality of portions, in a circumferential direction, of an annular body. The annular body includes: annular parts disposed on both sides in an axial direction; and pillar parts that are disposed at a plurality of portions in the circumferential direction and that connect between the annular parts. The pockets are formed by the annular parts and the pillar parts adjacent to each other in the circumferential direction, and allow ball guide. First contact portions of the pillar portions, which contact portions contact with the balls in the circumferential direction, are formed by first planes that extend along the axial direction, and the balls are guided by the first planes.

A rolling bearing for a sliding door includes an inner ring, an outer ring, a plurality of rolling elements arranged in a rollable manner in an annular space between the inner ring and the outer ring, and a jacket member formed of a resin composition and provided so as to cover the outer peripheral surface of the outer ring. The resin composition contains polyamide 66 and glass fiber. The polyamide 66 has a number average molecular weight of 34000 to 60000. The number average molecular weight is measured by gel permeation chromatography using hexafluoroisopropanol (HFIP) as a solvent and poly (methyl methacrylate) (PMMA) as a reference material. The content of the glass fiber is 10 to 40 mass %.

A sliding member of the present embodiment includes a bearing alloy layer and a coating layer provided on a sliding surface side thereof. The coating layer has a resin binder with sulfide particles dispersed therein. A covering portion is provided over specific particles and is made of metal oxide comprising the same metal element as a metal element constituting the sulfide particles. When measured by an X-ray photoelectron spectroscopy and an X-ray diffraction method, a ratio of a peak height of the metal oxide to a peak height of metal sulfide by the X-ray photoelectron spectroscopy is from 0.10 to 0.50, and a ratio of the peak height of the metal oxide to the peak height of the metal sulfide by the X-ray diffraction method is 0.10 or less.

The column portions of the cage includes roller holding portions which restrain the cylindrical roller on an outer diameter side and an inner diameter side thereof. The roller holding portions are formed such that a radial movement amount of the cage with respect to the cylindrical roller from a state where a revolution center of the cylindrical roller coincides with an axial center of the cage is configured so that an outer diameter side movement amount<an inner diameter side movement amount, and an outer diameter side opening width of the pocket portion>an inner diameter side opening width of the pocket portion. The column portion includes an inner diameter side protrusion which protrudes to an inner diameter side than inner circumferential surfaces of the annular portions and which configures the roller holding portions.
