A radial rolling bearing () with rolling bodies () which are received in at least one cage () and which are arranged between an inner ring () and an outer ring (). The radial rolling bearing () is radially separable, and the radially multipart inner ring () can be fixed on a shaft () using two clamping rings () which are attached to the axial ends of said inner ring. The inner ring () is designed without rims on the axially outer sides, and the clamping rings () take on the function of inner ring rims, the rolling bodies () running against inner run-on surfaces () of the clamping rings () in the axial direction. On the basis of the at least partial positioning of the clamping rings () axially below the cages () or the outer ring (), the clamping rings () take on two additional functions in addition to the actual clamping ring main function of fixing the inner ring () on the shaft (). Firstly, the clamping rings () form a cage guide in the radial direction, and secondly, the clamping rings assist the axial guiding of the rolling bodies () by the inclined inner run-on surfaces (). The radial rolling bearing additionally has a reduced axial installation dimension due to the special arrangement of the clamping rings () in the radial rolling bearing.

Radial roller bearing

A sealed anti-friction bearing (), including an annular sealing washer () which seals a rolling-body chamber () in the axial direction, wherein the sealing washer () has a fastening section () for connecting it fixedly to a bearing ring () of the anti-friction bearing () so as to rotate with it, and wherein the sealing washer () is anchored with its fastening section () in a circumferential groove () of the bearing ring. According to the invention, it is provided that the fastening section () has a first clamping element in the form of a barb () and a second clamping element in the form of an annular bead (), and that the barb () and the bead () enter into a non-positive connection with oppositely lying surfaces of the groove ().

Sealed anti-friction bearing

A toroidal bearing () including a multiplicity of barrel-shaped rolling bodies () which roll about a bearing axis () between an outer ring () having a raceway () and an inner ring () having a raceway () is provided. According to the invention, on a circumferential surface () facing away from the raceway () thereof, the outer ring () and/or the inner ring () has at least one lubricating groove (), wherein the lubricating groove () is connected to the raceway () via at least one lubricating bore ().

Toroidal bearing

Radial self-aligning rolling bearing including an outer ring, an inner ring, and balls which are arranged to roll in the raceways of the rings, and also spherical rollers together as rolling elements, which are all guided in a cage. The balls are larger in diameter than the spherical rollers, so that the balls exclusively take up the entire bearing load when the bearing load is small and both the balls and the rollers take up a larger bearing load.
