ABSTRACT:
An insulating roller cover is now disclosed that provides a highly desirable combination of features. The cover is free from asbestos and is therefore of more desirable construction for handling and use. For the roller cover, at least substantially ceramic fiber is highly compressed, providing a dense and refractory, elevated temperature resistant insulating cover. The cover may itself serve as a load bearing surface; or may provide a foundation or protective media for annular discs or sleeve members made of various, load bearing materials. These load bearing materials may be unable to resist direct contact with the shaft due to thermal shock or the differences in their respective expansion and contraction rates. Where impregnant is utilized with the highly compressed fiber, such will often comprise a colloidal substituent.
