Abstract
A spacer device for roller elements of a toroidal roller bearing includes an inner ring with an inner ring raceway and an outer ring with an outer ring raceway. The toroidal roller bearing allows for axial and angular displacement between the inner ring and the outer ring. The spacer device comprises at least one centering element that is arranged to extend in between adjacent roller elements in a longitudinal direction of the roller elements when the spacer device is in use. The at least one centering element is arranged to make contact with at least one of one point or a region of one of the inner ring raceway or the outer ring raceway when the spacer device is in use, whereby the spacer device is centered on the one of the inner ring raceway or the outer ring raceway.
