摘要：Roller bearing device for shafts, in particular, motor shafts, comprisign a tandem bearing, with an inner and an outer roller bearing when viewed in the axial direction of the shaft, operated under radial preload. Each bearing has an outer ring, both roller bearings (3a, 3b) being housed in a common bush (7) or similar and a device (11) is provided for compensating for the thermal changes to radial preload, comprising an expanding tapered ring (12) which may be axially displaced on the outer ring (6a) of the inner roller bearing (3a) which is axially preloaded by means of a tensioning element (18) which runs with the tapered surface (14) thereof on a further annular tapered surface (15).
