A roller assembly for the high-temperature transport of articles, including a ceramic roller with a longitudinal axis and two ends; at least one generally cylindrical metal end cap at one or both ends of the roller; and means arranged between the roller end and the end cap for rotationally interconnecting the end cap and the roller (2), axially securing the end cap (4) to the roller (2), and centring the roller (2) relative to the end cap (4). The means (10) for centring the roller relative to the end cap (4) are separate from the means (12) for rotationally interconnecting the end cap and the roller (2) and for axially securing the end cap (4) to the roller (2). The means (10) for centring the roller relative to the end cap (4) may consist of bimetallic members (14) or longitudinal or radial resilient members (16).
