Toroidal bearing i.e. single-row radial roller bearing, has cage comprising two cage side plates and bolt that penetrates through axial through holes, where bolt is connected with side plates in form-fit and/or force-fit manner

摘要

The bearing (1) has barrel-shaped rolling bodies (7) for rolling between two curved paths (3, 5) of respective outer and inner rings (2, 4) around a bearing axis (8). A cage (9) comprises two cage side plates (10, 11) and a bolt (12) that penetrates through axial through holes (13), where the bolt is connected with the plates in a form-fit and/or force-fit manner. The bolt and/or the plates are made of metal, and the rolling bodies are arranged at a distance from each other. The plates are formed by metallic annular disks. A groove (15) is formed on a front side of the plates.
