A roller bearing cage includes the following features: The cage comprises an annular circumferential element, from which bridge elements branch off, roller bodies of the roller bearing being disposable between the bridge elements, the circumferential element comprises a plurality of uniform section elements, and the initially-loose section elements and bridge elements are connected with each other to form the cage.

Rolling bearing cage

A bearing support is configured to retain at least two bearings disposed closely adjacent to each other in a parallel relationship. Each bearing includes a bearing outer ring having a cylindrical outer circumferential surface. The bearing support comprises at least first and second portions that are connected together. The first portion is formed as a component that has cylindrical openings configured to receive or seat the respective bearing outer rings and to surround the entire circumference of the respective bearing outer ring. The second portion is formed as a support plate. A bearing assembly includes the bearing support with a bearing seated in each of the respective cylindrical openings.

Bearing support

A bearing assembly comprises at least two adjacently-disposed bearings. Each bearing includes a bearing outer ring having a cylindrical outer circumferential surface. A bearing support retains the at least two bearings such that respective rotational axes of the at least two bearings extend in parallel. A spacer has at least two cylindrical openings configured to receive the respective cylindrical outer circumferential surfaces of the bearing outer rings such that a circumferential inner surface of each opening covers at least a portion of a width of the bearing outer ring received therein and surrounds an entire circumference of the bearing outer ring received therein. The bearing support is not fixedly connected to the spacer.

Bearing arrangement

A process for mounting an outer bearing ring involves press fitting a stamp into the outer ring so that the inner peripheral surface of the outer ring assumes the shape of the stamp. Using the stamp, the outer ring is then press fitted into the recess of a machine part so that the contour of the external peripheral surface of the outer ring is plastically molded through axial stretching into the machine part. To mount an inner ring, a stamp with a bore is press fitted onto the inner ring so that the inner peripheral surface of the inner ring pressing against the stamp assumes the shape of the bore of the stamp. Using the stamp, the inner ring is then press fitted onto the machine part and the contour of the inner peripheral surface of the inner ring is plastically molded through axial flow forming into the machine part.

Process for mounting bearing rings

A cylindrical roller bearing includes an outer bearing ring, an inner bearing ring and cylindrical rollers located between the outer and inner bearing rings. One of the rings has side rims forming an axial stop for the cylindrical rollers. The bearing ring on which the side rims are not provided is formed with at least one groove outside the axial extension of the cylindrical rollers. A ring of spring-elastic material is positioned in the groove to form an axial stop for the cylindrical rollers. The periphery of the ring has no interruptions. To improve the running behavior of the cylindrical roller bearing, the ring possesses a V-shaped cross-section with two legs.
