摘要： A double-row spherical roller bearing, comprising an outer ring including at least one spherical inner raceway on a radially inner peripheral surface, an inner ring including a first and second axial end and at least one outer raceway on a radially outer peripheral surface. Spherical roller elements are located in first and second roller rows interposed in-between the inner and outer raceways. A first flange is located at the first axial end, extending in a circumferential direction of the outer peripheral surface. The inner ring is subjected to an axial load in a first axial direction wherein the first flange approaches the first roller row. An axial extension of the first flange extends without contacting any first roller row roller elements during bearing operation, when an axial load is acting on the inner ring in the first axial direction. The bearing can be integrated into a wind turbine.

摘要： A bearing arrangement for low speed rotating machinery includes a shaft and at least one double row spherical roller bearing supporting the shaft. The bearing has an inner ring providing a radially outer circumferential surface having a first and a second inner raceway and an annular portion separating the first and second inner raceway in an axial direction. An outer ring provides a radially inner circumferential surface with at least one outer raceway. Spherical rollers are located in a first and a second roller row, the first and second roller row disposed between the at least one outer raceway and the first and second respective inner raceway. A cage has a central portion located between the roller rows. The central portion provides a radially inner circumferential surface and axial protrusions to separate at least two rollers in one of the first and second rollers rows.

摘要： A double-row spherical roller bearing comprising an outer ring which presents a first and a second spherical raceway on a radially inner peripheral surface, an inner ring which presents a first and a second outer curved-shaped raceway. Moreover, roller elements are arranged in a first and second roller row being axially displaced from each other, and arranged in-between the respective first and second inner raceways of the outer ring and the first and second outer raceways of the inner ring. The outer ring includes a first groove on the radially inner peripheral surface located in-between the first and second inner raceways, extending radially outwardly and in the circumferential direction of the ring. The first and second inner raceways have hard turned surfaces. The first groove presents a hardened surface which has not undergone any post-hardening machining operation. The double-row spherical roller bearing can be a wind turbine bearing arrangement.
