The invention relates to a transport roller, comprising at least one supporting tube (20a, 20b), which is mounted rotatably about an axis on a first end by means of a first rolling bearing (30) and is mounted rotatably about the axis on a second end by means of a second rolling bearing (40), wherein the first and second rolling bearings provide a fixed/floating bearing arrangement in that, on an inner ring (31, 41) or outer ring (32, 42) of the first or second rolling bearing, an axial relative movement is provided between the supporting tube (20a, 20b) in relation to the axis in both axial directions by an appropriately displaceable mount of an inner ring (31, 41) or outer ring (32, 42) in relation to the axis or supporting tube (20a, 20b), and the inner rings (31, 41) of the first (30) and second (40) rolling bearing are disposed on a shaft, which is mounted rotatably about the axis by means of the rolling bearings and the supporting tube (20a, 20b) is connected to said shaft (10) in a torque-proof and axially non-displaceable manner. In a transport roller according to the invention, a sliding bushing (33, 43) is disposed such that the axial relative movement takes place between the inner ring (31, 41) or outer ring (32, 42) and the sliding bushing (33, 43). |
