ABSTRACT:
A bearing assembly includes an inner ring and outer ring defining opposed raceways having a plurality of bearing elements disposed therebetween. The bearing assembly includes an improved sealing arrangement having multiple primary seals for providing sealing with the rotating inner ring. In preferred embodiments, the multiple seals include a rolled riding seal and an oblique contact seal having a center lip therebetween. Unlike the other two primary sealing lips, the center lip preferably provides no more than light engagement with the bearing inner ring. Flingers or configured mounting collars may also be provided to further enhance sealing characteristics
