1. A roller assembly for transporting articles at high temperatures comprising:

  • a ceramic roller having a longitudinal spindle and two ends;

    at least one generally cylindrical, metallic fitting mounted to at least one end of the roller, at least one end of the roller including a planar surface;

    means for linking in rotation the fitting and the roller, for axially retaining the fitting with respect to the roller; and

    means for centring the roller relative to the fitting, the means for linking in rotation the fitting and the roller and for axially retaining the fitting with respect to the roller being separate and independent of the means for centering the roller relative to the fitting, said means for linking being able to compensate the differential thermal expansion of the fitting with respect to the roller at said high temperature, wherein said means for linking in rotation the fitting and the roller and for axially retaining the fitting with respect to the roller consist of a bimetallic, elastic leaf fixed to the fitting and applied to said planar surface on said at least one end of said roller.
