Abstract
A spacer device for roller elements of a toroidal roller bearing includes an inner ring and an outer ring. The toroidal roller bearing allows for axial and angular displacement between the inner and outer rings. The spacer device comprises a first roller element-contacting surface and a second roller element-contacting surface on opposite sides thereof. First and second roller-contacting surfaces are arranged to separate two adjacent roller elements in a tangential direction of the toroidal roller bearing when the spacer device is in use. Each of the first and second roller element-contacting surfaces has a concave shape adapted to conform to respective convex contacting surfaces of the roller elements. The spacer device comprises end members that have projections that extend outwards from first and second roller-contacting surfaces and which are arranged to extend at least partly over the ends of two adjacent roller elements when the spacer device is in use.
