Disclosed is a cylindrical roller bearing for absorbing axial and radial forces. The roller bearing includes a first bearing ring and a second bearing ring, which are arranged concentrically about an axis of rotation extending in an axial direction. The second bearing ring has a groove, which is open in a radial direction and in which a projection of the first bearing ring engages. The roller bearing further includes a first radial bearing row and two axial bearing rows spaced in the axial direction that are arranged between the projection and the groove, wherein the first radial bearing row supports the first bearing ring against the second bearing ring in a first radial direction. The roller bearing also includes a second radial bearing row that supports the first bearing ring against the second bearing ring in a second radial direction that is opposite to the first radial direction. The first bearing ring is divided in the axial direction into at least one first ring part having the projection and one second ring part, wherein the second radial bearing row is arranged between the second ring part and the second bearing ring at an axial distance from the projection.

1. A cylindrical roller bearing for absorbing axial and radial forces, comprising: a first bearing ring having an axis of rotation running in an axial direction (x), said first bearing ring being divided, in the axial direction, into at least one first ring part having a lobe protruding therefrom, and a second ring part disposed adjacent said first ring part;a second bearing ring concentrically disposed about an outer periphery of said first bearing ring, said second bearing ring having a groove defined therein that is open in a radial direction and into which groove said lobe of said first bearing ring is positioned;a first axial bearing row and a second axial bearing row, each disposed between said lobe of said first bearing ring and said groove of said second bearing ring, said first and second axial bearing rows being spaced apart from each other in the axial direction;a first radial bearing row disposed between said lobe of said first bearing ring and said groove of said second bearing ring, said first radial bearing row being configured to support said first bearing ring against said second bearing ring in a first radial direction; anda second radial bearing row that is, disposed between said second ring part of said first bearing ring and said second bearing ring,disposed either above or below said first and second axial bearing rows so that it does not project in the radial direction beyond said first and second axial bearing rows, andspaced axially apart from said lobe,said second radial bearing row being configured to support said first bearing ring against said second bearing ring in a second radial direction that is opposite said first radial direction. 2. The cylindrical roller bearing of claim 1, wherein said second ring part and said second bearing ring each have a projection that respectively engage behind one another in the axial direction (x) and in the radial direction, and wherein said second radial bearing row is arranged between said respective projections of said second ring part and said second bearing ring. 3. The cylindrical roller bearing of claim 2, wherein said respective projections of said second ring part and said second bearing ring each have an L-shape with a radial limb and a free axial limb. 4. The cylindrical roller bearing of claim 1, comprising a face surface defined, in the axial direction (x), by said second ring part. 5. The cylindrical roller bearing of claim 1, wherein said second radial bearing row does not project in the radial direction beyond the region in which said axial bearing rows and said first radial bearing row are arranged. 6. The cylindrical roller bearing of claim 5, wherein said second radial bearing row does not project in the radial direction beyond said axial bearing rows. 7. The cylindrical roller bearing of claim 1, wherein said second bearing ring is divided in the axial direction (x) in a region of the groove. 8. The cylindrical roller bearing of claim 1, wherein said first bearing ring and said second bearing ring each have, distributed around a circumference thereof, passage holes for fastening screws. 9. The cylindrical roller bearing of claim 1, wherein said first bearing ring forms an inner ring and said second bearing ring forms an outer ring. 10. The cylindrical roller bearing of claim 1, wherein at least one of said first bearing ring or said second bearing ring have radial supply ducts for lubricant.
