seal which is stamped into place in the outer ring of the bearing to reduce the possibility of being pushed out from over-lubrication. The first seal makes contact with the inside of the slinger which provides the first line of defense against contamination. The next seal makes contact with the inner ring to provide another level of contamination resistance. An additional level of protection exists in the extra non-contact inward facing lip which allows grease to flow back towards the balls and raceways during operation thereby improving lubrication performance and extending bearing life.

FYH FloBack seal design allows for excellent bearing outer ring roundness which maintains the FYH “J” fitting tolerance with all housings and mounting configurations.
Allowable rotating speed is same as the previous seal design.
