A roller bearing includes inner and outer rings, and a plurality of rolling bodies configured to roll in two rows on corresponding raceways on the inner and outer rings. At least one of the inner ring and outer ring is split radially to form at least two ring portions. The raceway in an abutment region between the at least two ring portions has a ground recess locally deepening the raceway. Each ground recess on the outer ring has an arcuate course extending transversely to the abutment region, the greatest radial depth of the ground recess lies in the abutment region, and each ground recess extends in the circumferential direction of the raceway of the outer ring over a length which is at most the circumferential distance between the contact point of a first rolling body and the contact point of a second rolling body.

Roller bearing

A rolling bearing has an inner and an outer bearing ring. Each bearing ring has an inner and an outer shell surface. The roller bearing has rolling elements, which roll on raceways provided on the respective shell surfaces of the bearing rings, and a sealing disc connected to one of the bearing rings and operatively connected in a sealing manner to the other bearing ring. To connect the sealing disc to the bearing ring, one of the shell surfaces of the one bearing ring includes a first connecting means and the sealing disc includes a second connecting means. The first connecting means provide a rotating engagement in which the second connecting means engage in a connected state of the bearing ring and the sealing disc.

Roller bearing with a seal

A cage of a roller bearing includes at least two cage segments, wherein each cage segment is formed from two side pieces, which are disposed at an axial distance from one another, and from a plurality of webs that are circumferentially distanced from each other and that connect the side pieces in the axial direction, wherein each cage segment forms an arc of a given arc length, the plurality of webs includes a center web, which maintains a distance of half the given arc length from the circumferential ends of the respective cage segment, and wherein the center web is penetrated by a bore the center axis of which approximately runs through the center of gravity of the cage segment, and which is configured to accommodate a radially outwardly directed moving device in a releasable manner.

Cage

A roller bearing cage for guiding rolling bodies in a rolling body bearing, which has multiple rolling bodies, two cage side elements, between which the rolling bodies are arranged, and which have multiple web appendages to guide the rolling bodies, and multiple connection elements that connect the two cage side elements. The azimuthal position of the connection elements defines a connection area. Exactly one connection element and at least one web appendage are arranged in a connection. The connection element and web appendage are arranged in sections inside a radial interior of the respective cage side elements, the border of which is defined by the positions of the rotation axes of the rolling bodies.
