Abstract
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.
