A split bearing cage for a rolling-element bearing assembly includes a first bearing cage segment and a second bearing cage segment each having two side ring sections axially spaced apart by a plurality of bridges. Adjacent pairs of the bridges define rolling-element receiving pockets for receiving rolling elements of the rolling-element bearing assembly and for holding the rolling elements spaced apart from each other and for guiding the rolling elements. The first bearing cage segment is connected to the second bearing cage segment via a swivel joint that may be formed of a bolt element on a first end of the first bearing cage segment and an at least partial eyelet on the first end of the second bearing cage segment.

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

The invention relates to a roller bearing cage comprising: a first annular ring; a second annular ring; at least one retainer portion attaching the first annular ring to the second annular ring to form the first and second annular rings in a cylinder-type structure; and a plurality of resilient tangs on each of the first and second annular rings, each tang protruding from the circumference of the respective annular ring at an angle with respect to the plane of the respective annular ring and toward the other annular ring.

A spherical roller bearing having an outer ring providing at least one inner raceway, an inner ring providing a first and a second outer raceway, a plurality of roller elements arranged in a first and second roller row in-between the at least one inner raceway and the respective first and second outer raceway is provided. The bearing provides a cage for guiding the roller elements in the first and second roller row, the cage includes a plurality of cage pockets, wherein in each cage pocket one of the roller elements is disposed. The bearing further presents a specific pitch circle diameter (PCD), and the cage is essentially in-pitch roller centered in relation to the pitch circle diameter (PCD) when there is an axial force acting on the bearing. In addition, the present invention regards a bearing arrangement and a wind turbine bearing arrangement.

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.

A bearing assembly includes a split inner race ring configured to be installed on a shaft and defines two raceways for supporting rolling elements. A split clamping band is configured to be installed over the split inner race ring to secure the split inner race ring on the shaft. A split seal wear ring is configured to be installed on an outer diameter surface of the split clamping band. An engagement interface between the split clamping band and the split seal wear ring includes a boss on one of the split clamping band and the split seal wear ring, and an aperture on the other one of the split clamping band and the split seal wear ring. The aperture is sized and configured to receive the boss for positioning the split seal wear ring on the split clamping band.

An improved bearing cage is disclosed herein. The bearing cage assembly generally consists of two cage halves that are connected, fixed, or joined to each other directly via mating components formed integrally with the two cage halves. The cage halves are joined to each other via engagement of integrally formed sockets and posts defined on radially extending arms of the cage halves.

A bearing assembly (100) includes a split inner race ring (115) configured to be installed on a shaft (25) and defines two raceways (135, 140) for supporting rolling elements (150,155). A split clamping band (170) is configured to be installed over the split inner race ring (115) to secure the split inner race ring (115) on the shaft (25). A split seal wear ring (290, 295) is configured to be installed on an outer diameter surface of the split clamping band (170). An engagement interface between the split clamping band (170) and the split seal wear ring (290, 295) includes a boss (340) on one of the split clamping band (170) and the split seal wear ring (290, 295), and an aperture (355) on the other one of the split clamping band (170) and the split seal wear ring (290, 295). The aperture (355) is sized and configured to receive the boss (340) for positioning the split seal wear ring (290, 295) on the split clamping band (170).
