Abstract
A roller for use in a fuser assembly of a reproduction apparatus adapted to operate at an elevated temperature up to in the range of approximately 750° F. The roller includes a generally elongated substantially cylindrical tube. End gudgeons are provided for sealing the ends of the cylindrical tube. Each of the end gudgeons is respectively associated with an end of the cylindrical tube such that after a weld joint is formed between the cylindrical tube and the end gudgeon, the end gudgeon provides a compression joint to prevent the cylindrical tube from separating from the end gudgeon, due to material creep, at elevated operating temperatures.
