ABSTRACT:
A bearing arrangement for a harvesting machine, including a bearing configured to couple a rotatable shaft with a chassis of the harvesting machine, a first element coupled with the shaft so as to be rotatable therewith, and a second element coupled with the chassis of the harvesting machine. Additionally, at least a portion of the second element is substantially concentrically enclosed by the first element and the first and second elements cooperate to define a contactless seal configured to substantially prevent contamination of the bearing. The shaft is coupled with a product treating element, such as a crop feeding and/or processing element that is driven or idle rotating.
