A retaining element for retaining a component within a receiving part, the retaining element including: a neck portion to be received within a notch formed in the receiving part; a first head portion coupled to the neck portion end and defining a first shoulder; a second head portion coupled to another neck portion end and defining a second shoulder, wherein the first and second shoulders oppose one another and are to abut first and second surfaces of the receiving part so as to engage the retaining element with the receiving part; wherein the first and/or second head portions include a retaining tab having a retaining surface, wherein the retaining tab has a receiving position for receiving the component and retaining position for retaining the component; wherein, in the retaining position, the retaining tab extends beyond the neck portion so the retaining surface abuts the component surface to retain the component.

A sliding contact surface-forming material includes a reinforcing base impregnated with a resol-type phenolic resin having polytetrafluoroethylene resin dispersed therein. The reinforcing base is composed of a woven fabric formed by using, respectively as the warp and the weft, a ply yarn which is formed by paralleling at least two strands of a single twist yarn spun from fluorine-containing resin fiber and a single twist yarn spun from polyphenylene sulfide fiber, and by twisting them in the direction opposite to the direction in which the single twist yarns were spun. Also, a multi-layered sliding contact component having the overall shape of a flat plate or a circular cylinder includes the sliding contact surface-forming material so as to configure at least the sliding-contact surface thereof.

Embodiments of the invention are directed to compact bearing assemblies configured to operate in small spaces and/or in harsh environments, bearing apparatuses including such bearing assemblies, and method of operating such bearing assemblies and apparatuses. For instance, one or more compact bearing assemblies may at least partially rotatably secure a shaft of a power generation unit to a housing thereof. Also, a first compact bearing assembly may connect or couple to the shaft and may rotatably engage a second compact bearing assembly, which may be connected or otherwise secured to the housing.

A cap for a motion guide apparatus which can reduce generation of a burr and can also increase the fixing force. The cap of the present invention is for blocking a fastening member insertion hole of a guide rail of a motion guide apparatus. The cap includes a disc-shaped top surface portion, a cylindrical side surface portion hanging down from the top surface portion, and a plurality of protrusions provided on an outer peripheral surface of the side surface portion. The plurality of protrusions is apart from each other in a circumferential direction on the outer peripheral surface of the side surface portion, and is present at an upper end portion, or from the upper end portion to an axially middle portion, of the outer peripheral surface. A thickness of the side surface portion between the protrusions is less than a thickness of the top surface portion.

Embodiments of the present disclosure are directed to an adhesive layer, bearing including the adhesive layer, and methods of forming. The adhesive layer can include a mixture of a first polymer, a second polymer, and a third polymer, wherein the third polymer is a modified fluoropolymer of the second polymer. In a particular embodiment, a weight ratio of a weight content of the second polymer to a weight content of the third polymer in the mixture can be at least 12:1. In another particular embodiment, the adhesive layer can have a normalized peel strength of at least 4.8 N/in/microns.

A bearing including a substrate and a low friction layer, where the bearing includes an annular shape including a radial bearing portion in the form of an axially-extending base region, and an axial bearing portion in the form of a radially-extending flange, where the axial bearing portion terminates in a deep drawn axially extending lip, and at least one of a radial coining region or an axial coining region, where the radial coining region is positioned along the radially-extending flange and forms an annular depression, where the axial coining region is positioned along the axially-extending base region, and where the axial coining region is deformed so as to be non-parallel to a longitudinal axis of the bearing.

An end stop cap for a rolling bearing for mounting in a railway axle box of a respective support device. The cap being a concave disc delimited by a lateral wall having a symmetric axis, coaxial with a bearing's symmetric axis by an end wall, transverse to the symmetric axis, and by an elbow-shaped transition connecting the end and lateral walls. Holes extend through the end wall for fastening screws. The lateral wall terminates on the side opposite the end wall in an annular frontal surface which rests against a bearing ring.
