The bearing assembly concept includes a floating seal arrangement. In one form, a bearing assembly comprises a first bearing member and a second bearing member that is oriented adjacent to the first bearing member. A plurality of bearings is positioned between the first bearing member and the second bearing member. A shield is engaged with the first bearing member, and a floating seal is slidably engaged with the shield and the second bearing member. The shield captures the floating seal adjacent to the second bearing member.

The bearing assembly of claim 8, wherein the arcuate bearing face of the floating seal is coated with at least one of a chrome plating and a ceramic coating. 12. The bearing assembly of claim 11, wherein: the first bearing member rotates relative to the second bearing member about the longitudinal axis; andthe shield face is substantially planar and oriented substantially perpendicular to the longitudinal axis. 13. The bearing assembly of claim 8, wherein: a groove is formed in the first bearing member; andthe shield is captured in the groove. 14. The bearing assembly of claim 8, wherein the shield defines a contoured profile configured to bias the floating seal toward the second bearing member. 15. A bearing assembly, comprising: an outer ring having an outer race;an inner ring having an inner race, the inner ring oriented radially inward of the outer ring;a plurality of bearings positioned between the outer ring and the inner ring, the plurality of bearings seated in the inner race and the outer race;a shield coupled to the outer ring; anda floating seal slidably engaged with the shield and the inner ring during operation of the bearing assembly, the floating seal made of at least one of a metallic material and a ceramic material;wherein the floating seal defines an arcuate bearing face engaged with the inner ring, a radial face positioned radially outward from the arcuate bearing face, and a flange extending radially outward from the radial face defining an axial shield face that is engaged with the shield;wherein the arcuate bearing face engaged with the inner ring extends longitudinally beyond axial ends of the shield; andwherein the shield restrains the floating seal adjacent to the shield and the inner ring allowing the floating seal to glide relative to the shield and the inner ring during operation of the bearing assembly. 16. The bearing assembly of claim 15, wherein the floating seal is made of at least one of an alloy steel and a stainless steel. 17. The bearing assembly of claim 15, wherein: the inner ring rotates relative to the outer ring about a longitudinal axis; andthe shield face is substantially planar and oriented substantially perpendicular to the longitudinal axis. 18.
