Each beam includes, at a lateral end, a protuberance of concave outer form and intended to come into contact with the outer surface of at least one roller, two protuberances being opposite in the circumferential direction for each through pocket.

A lubricant injector includes a lubricant inlet, a lubricant outlet, a control piston and a metering piston. The control piston is configured to conduct lubricant from the lubricant inlet to the metering piston, and the metering piston is configured to pump the lubricant provided by the control piston to the at least one lubricant outlet. The metering piston includes a first metering chamber and a second metering chamber that are each connected to the at least one lubricant outlet. The lubricant injector further includes first and second lubricant channels, and in a first switching state of the control piston the lubricant inlet is connected via the first control space to the first lubricant channel and the second metering chamber, and in a second switching state the lubricant inlet is connected via the second control space to the second lubricant channel and the first metering chamber.

The invention relates to a rolling element bearing cage formed of one or more segments, each segment comprising: a supporting frame having a plurality of spaced apart openings each for accommodating a rolling element; and a reinforcing frame, inserted within the supporting frame, having a corresponding plurality of openings each for aligning with the openings of the supporting frame.

First and second bearing cage halves each having an annular base body and a plurality of pins extending from the base body and a plurality of pin receptacles, the first and second cage haves forming a bearing cage when the pins are received into the pin receptacles. A body of sacrificial material is located on the pins and/or in the pin receptacles which body is configured to be melted ultrasonically to join the first cage half to the second cage half and form the bearing cage.

A rolling bearing includes an inner ring having an outer surface, an outer ring having an inner surface, a plurality of rolling elements rotatably disposed between the inner ring and the outer ring, and a retainer for retaining the rolling elements. The retainer is made of a resin material and is positioned with respect to the inner surface of the outer ring or the outer surface of the inner ring. The retainer includes a pair of annular portions axially arranged in parallel and a columnar portion coupling the annular portions. Then, the rolling bearing satisfies the following expression: .[.AI=LH.sup.3/dm≥0.025.]. .Iadd.LH.sup.3/dm.sup.2≥0.025 mm.sup.2 .Iaddend.in which H is a radial length of a section of the annular portion, L is an axial length of the same, and dm is PCD of the rolling element.

A roller bearing for a pod joint comprising an inner race, an outer ring assembly, a race that runs along a bell section and is disposed on the outer surface of the outer ring assembly, a plurality of rolling elements, wherein the plurality of rolling elements are disposed between the inner race and the outer ring assembly and are formed as rollers, and a cage assembly, wherein the rolling elements are disposed in the cage assembly, wherein the cage assembly is formed as a central cage, wherein the rollers pass through the central cage in a middle area, and the running areas thereof project outward from both sides of the central cage.

A bearing cage assembly is disclosed. The assembly includes a stiffening ring formed from a first material, and a cage formed from a second material that is different than the first material. The cage includes a plurality of arms extending axially away from a base rim. The plurality of arms define a plurality of rolling element pockets therebetween. Each of the plurality of arms defines a slot dimensioned to receive a portion of the stiffening ring, such that the stiffening ring is secured to the cage via engagement within the slots of the plurality of arms.

A method and device for fitting an angular contact roller bearing, including an inner bearing ring having an inner race arranged on the outer peripheral surface of the inner bearing ring and inclined with respect to the axis of rotation of the bearing, and a rim delimiting said race at the smallest diameter thereof, an outer bearing ring having an outer race arranged on the inner peripheral surface of the outer bearing ring and inclined with respect to the axis of rotation of the bearing, and a rim delimiting said race at the greatest diameter thereof, and also including a plurality of roller bearing elements arranged between the bearing rings and roll on the races and are held at uniform distances from one another in the circumferential direction by a bearing cage. The outer peripheral surface of the inner bearing ring and the inner peripheral surface of the outer bearing ring are in each case cylindrical and extend outside the races at least in some sections coaxially with respect to the axis of rotation of the bearing, and the races of both bearing rings are in each case integrated conically into the cylindrical peripheral surfaces, such that the rims which are produced and in each case delimit the races on one side are in each case formed in one piece with the bearing rings. The fitting of the angular contact roller bearing takes place according to an eccentric pivot fitting method the deep groove ball bearing eccentric fitting method.
