ABSTRACT:
Apparatus for inserting a substrate surrounded by a compressible mat into a compartment of a housing of an exhaust treatment device includes an insertion member having a bore shaped substantially identically to a shape of an opening to the housing compartment and a fluid bearing generator establishing a compressed fluid bearing at a surface of the bore. The fluid bearing is operative to reduce a coefficient of friction between the compressible mat and a surface of the bore when the substrate/mat combination is moved axially in the bore into the compartment opening.
