A bearing cage segment for a rolling-element bearing includes at least one sliding surface on which a surface of at least one rolling element of the rolling-element bearing is rotatable, a first support element, such as an axial projection on an axial side of the cage segment having a radially open radially facing channel, at a first radial position for supporting a first band section of a band clamp during an assembling of the rolling-element bearing, and at least one second support element at a second radial position different from the first radial position for supporting a second band section of the band clamp.

A socket for a ball joint having a socket body with an opening and a hollow space, which comprises a concave inside peripheral surface that delimits the hollow space and extends around a longitudinal axis, and which is axially divided into two body halves which merge together in a transition zone, each of which comprises an inside peripheral surface half. A first body half comprises a first inside peripheral surface half which lies on a spherical surface and is closed, in the circumferential direction, and a second body half which comprises the socket opening, at least one slot extending axially and a second inside peripheral surface half which is closed in the circumferential direction, or closed apart from the slot. The second body half is designed such that the second inside peripheral surface half lies outside the spherical surface at least an axial distance away from the transition zone.

A difference between a maximum value and a minimum value of arithmetic mean roughness Ra of an annular surface region in contact with a larger flange surface, in a larger end face of the tapered roller, is not greater than 0.02 μm. A value of a ratio R/R.sub.BASE is not smaller than 0.75 and not greater than 0.87 where R represents a set radius of curvature of the larger end face of the tapered roller and R.sub.BASE represents a distance from a point which is an apex of a cone angle of the tapered roller to the larger flange surface of the inner ring. A ratio R.sub.process/R is not lower than 0.5 where R.sub.process represents an actual radius of curvature after grinding of the larger end face of the tapered roller and R represents a set radius of curvature.

A rolling bearing includes a cage formed by coupling a first and a second division pieces into which the cage is divided in an axial direction. At least the first division piece is provided with a protruding portion extending in an axial direction toward the second division piece and having a locking portion formed at a tip of the protruding portion with the locking portion protruding toward a radially outer side. The second division piece is provided with a locked recessed portion in which the locking portion is locked. On an inner peripheral surface of the first division piece, an avoiding recessed portion is formed which allows avoidance of interference of the inner peripheral surface of the first division piece with an inner ring when the first division piece is tilted toward a radially inner side in order to lock the locking portion in the locked recessed portion.

The invention relates to a bearing arrangement for a drilling head, through which flushing liquid flows, of a deep drilling device, having multiple radially outer and radially inner bearing rings, wherein the radially outer bearing rings are arranged coaxially over the radially inner bearing rings, wherein, radially between the bearing rings, there are arranged balls which roll in raceways of the bearing rings, and wherein the raceways are delimited axially on both sides by shoulders with mutually opposite shoulder surfaces which run parallel to a bearing longitudinal axis. In order for a bearing arrangement of this type, which, as per the prior art, is adjoined in an axial direction by at least one plain bearing, to be designed to be of short axial extent and in order to simplify the construction, the internal diameter (Di) of the shoulder surfaces of the radially outer bearing rings and the external diameter (Da) of the shoulder surfaces of the radially inner bearing rings are dimensioned such that said shoulder surfaces perform the function of parallel radial plain bearings with a radial clearance (S).

A hub-bearing unit is provided with: a rotatable hub, with an axially outer flange portion configured for engagement with a rotatable element of a motor vehicle, a bearing unit provided with a fixed radially outer ring, configured for engagement with a fixed element of the motor vehicle, a first, axially outer, crown of rolling bodies, and a second, axially inner, crown of rolling bodies, interposed between the radially outer ring and the hub. The hub also assumes the function of the radially inner ring of the bearing unit and the bell of a constant velocity joint. The hub-bearing unit is designed so that the axial distance between the center of the axially inner crown of rolling bodies and the rolling center of the constant velocity joint lies within a predetermined range according to the following formula:

[00001]$\{\begin{array}{cc}\mathrm{with}.Math..Math.L\ge 0,& 0.4\le \frac{P_B}{S+A+L}\le 4\\ \mathrm{with}.Math..Math.L<0,& 0.5\le \frac{P_B}{S+A}\le 4.Math.\end{array}\hspace{1em}$

A roller bearing includes an outer raceway, an inner raceway, and a roller positioned between the outer and inner raceways. The roller bearing also includes a relief contour between the roller and at least one of the outer and inner raceways. The relief contour defines a slope along its length. The slope of the relief contour defines at least one inflection region.

A turbocharger includes a turbine, a compressor, and a bearing housing forming a bearing bore. A bearing arrangement is disposed between a shaft interconnecting the turbine and compressor wheels, and the bearing housing. The bearing arrangement includes first and second bearings formed between an outer bearing race element disposed within the bearing bore an inner bearing race element disposed within the outer bearing race element and between the outer bearing race element and the shaft. The inner bearing race element includes a flared portion extending radially outwardly to provide torsional and bending rigidity to the shaft.

Provided is a resin cage for a tapered roller bearing in which a mold parting line which is extended in an axial direction is formed in a pillar portion defining a pocket. On facing surfaces of adjacent pillar portions, on an outer diameter side from the mold parting line, a first conical surface which slides in contact with an outer peripheral surface of a tapered roller is formed, and a first flat surface in a radial direction is formed in a portion on the outer diameter side from the first conical surface. On an inner diameter side from the mold parting line, a second conical surface which slides in contact with the outer peripheral surface of the tapered roller is formed, and a second flat surface in a radial direction is formed in a portion on the inner diameter side from the second conical surface

A bearing component can include a metal substrate layer, shaped so as to include a generally annular sidewall having a central axis and defining a first and a second opposite ends in an axial direction; and a radial flange bent so as to extend in a radial direction from one of the first and second ends of the generally annular sidewall, wherein, in a pre-shaped state, the metal substrate layer includes at least two flange segments extending in the axial direction and defining a gap extending toward an opening.
