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 axial needle bearing includes a sheave and a cage. The sheave includes a radially outer sheave section having a rolling body race, a connecting angled thrust rib, and a ring section which is connected to the thrust rib and axially offset with respect to the sheave section. The disc-like cage retains bearing needles in pockets rolling on the rolling body race. The cage is fixed in position axially by a plurality of retaining sections extending radially from the ring section over the thrust rib and engaging over the cage, beneath each of which retaining sections a recess is provided in the sheave. The recesses beneath the retaining sections have a U-contour as they are worked into the sheave and are designed to extend with the web of the U-contour into the sheave section and with the ends of the U-contour into the ring section.

An outer ring includes an outer ring small-diameter part extending toward one axial side with respect to the outer ring raceway, a radial wall part extending from an axial end portion of the outer ring small-diameter part toward an inner diameter-side, and a folded-back part extending from a radially inner end portion of the radial wall part toward the other axial side. The folded-back part radially overlaps the inner ring small-diameter part with a radial gap therebetween. The radial gap of an inner diameter-side entry formed by an axial end of the folded-back part and the inner peripheral surface of the inner ring small-diameter part is smaller than the radial gap of an inner diameter-side exit formed by an axial end of the inner ring small-diameter part and an outer peripheral surface of the folded-back part.

A pulley device configured to support a belt of a chain tensioning idler or runner roller includes a bearing having a rotatable outer ring and a coaxial fixed inner ring and a pulley having at least one C-shaped pulley part that has an inner portion with an inner surface mounted on an outer cylindrical surface of the bearing outer ring, an outer cylindrical portion having an outer cylindrical surface configured to contact the belt or the chain, and a radial intermediate portion between axial outer ends of the inner and outer cylindrical portions and an axial outer end of the outer cylindrical portion, wherein a ratio between a radial material thickness of the outer cylindrical portion and a radial material thickness of the inner cylindrical portion is strictly greater than 1.

A sheet-metal bearing cage segment has a first ring section, at least one second ring section and a plurality of bridges connecting the first ring section and the at least one second ring section to each other such that a pocket for receiving at least one rolling element is formed between each circumferentially adjacent pair of the bridges. The first and/or second ring section includes at least one recess on the radially inner side and/or the radially outer side.

A roll-forming manufacturing method of a roller bearing seal case includes (a) roll-forming, from a cylindrical ring, a first profiled ring having a first section extending along cylinder axis of the cylindrical ring and a second section extending from the first section inward toward the cylinder axis, (b) applying outward pressure to the first section, in direction away from the cylinder axis, to round the first section, and (c) roll-forming a second profiled ring from the first profiled ring.

A manufacturing method of a slinger, includes steps of: molding an annular blank material from a dull-finished steel sheet material through sheet metal press working or the like; and burring the blank material to mold a slinger. The values of the arithmetical mean roughness Ra of faces, of a burring mold, which individually come into contact with first and second slide-contact surfaces of the slinger, are set to 0.03 mRa0.07 m. A ratio of pressure application force for holding the blank material between the faces to the 0.2% proof stress of the dull-finished material, is set to 1.0 or more and 1.53 or less. A clearance for the burring mold is set to T(0.9 to 0.7) where T represents the sheet thickness of the blank material.

Methods and apparatus for manufacturing a circular laminated component are disclosed herein. In one embodiment, a method comprises stamping an inlet stock of material to form a line of arc segments, the line of arc segments having: a plurality of notches along a first edge; a first longitudinal end; and a second longitudinal end opposite the first longitudinal end; wrapping the line of arc segments to form a circular segment having the first edge along an inner-circumferential diameter of the circular segment; joining the first longitudinal end to the second longitudinal end to form a circular laminate layer; and stacking a plurality of circular laminate layers to form a laminate disc.

A thrust roller bearing includes rollers, a cage that holds the rollers in a manner that allows the rollers to roll, and a washer including a raceway surface on which the rollers roll. The washer includes a raceway portion that has the raceway surface and is disposed on a first axial side of the cage, and hook portions that extend toward a second axial side. Each of the hook portions includes a first projecting portion that extends toward the second axial side from the raceway portion, a second projecting portion that extends radially toward the rollers and toward the second axial side from an end portion of the first projecting portion on the second axial side, and a third projecting portion that further projects radially toward the rollers from an end portion of the second projecting portion on a side opposite to the first projecting portion.

A roll-forming manufacturing method of a roller bearing seal case includes (a) roll-forming, from a cylindrical ring, a profiled ring including a first section extending at least along a cylinder axis of the cylindrical ring and a second section extending from the first section inward toward the cylinder axis, and (b) trimming the second section to expand the first aperture to achieve location and geometry according to design parameters. A roll-forming manufacturing method of a roller bearing seal case includes (a) roll-forming, from a cylindrical ring, a first profiled ring having a first section extending along cylinder axis of the cylindrical ring and a second section extending from the first section inward toward the cylinder axis, (b) applying outward pressure to the first section, in direction away from the cylinder axis, to round the first section, and (c) roll-forming a second profiled ring from the first profiled ring.
