Abstract
An fuser apparatus for minimizing heat transfer between an end of a fuser roll and a fuser bearing includes a generally cylindrical fuser collar positioned between one end of the fuser roll and one of the fuser bearings and having an outer surface contacting the fuser bearing and an inner surface contacting the fuser roll. A plurality of protrusions are formed on either the inner surface or outer surface of the collar to reduce the heat transfer between the fuser roll and fuser bearing. Grooves supporting O-rings may also be formed in the collar or in an end of the fuser roll for allowing the fuser roll to move axially relative to the collar.
