The invention relates to a roller (10a, 10b) for treating nonwoven, textile, plastic or paper material webs, comprising a roller body (11), which forms a working periphery (15) and at each of the two axial end regions of which a roller journal (12, 12') offset from the working periphery (15) axially protrudes, on which roller journals respective bearing receptacles (30, 30') are arranged in order to support the roller (10a, 10b). At least one coupling element (31, 32), which can be coupled at least to a lifting means (40) in such a way that an interlocking connection is formed, is formed on the bearing receptacle (30, 30').
