Beschreibung
Zusammenfassung:	A roller assembly having a roller tube, a fixed shaft inside the roller tube, a bearing mounted on the shaft, an inner casing mounted on the bearing and rotatable with respect to the shaft, an outer casing fixedly mounted on the shaft, a shield cap mounted on the inner casing, and a seal member mounted between the roller tube, the shield cap and the inner casing for sealing the roller assembly. Facing walls of the inner casing and outer casing define inner cells and a first labyrinth path for reducing migration of contaminants through the inner cells. Facing walls of the outer casing and shield cap define outer cells and a second labyrinth path for reducing migration of contaminants through the outer cells. The facing walls of the outer casing and shield cap are provided with gel for further reducing migration of contaminants through the outer cells.
