Abstract
A contamination-resistant bearing assembly includes an outer ring mounted within a housing and an inner ring rotatably supported from the outer ring. Inboard and outboard seal structures are disposed within a bearing space defined between the rings and prevent contaminants from entering a rolling element lubrication zone. A surface seal may also be included to protect the spherical interface between the housing and outer ring. The improved structure allows dynamic alignment of the bearing assembly when acted on by outside forces and also allows for extended operation under maintenance free conditions with no need for relubrication.
