mine says 7 19 on one side and 720 on the other I suspect those are lot numbers. keep in mind all the information on the seal is just information for the seal. that's why you want and use the number on the box ... although searching the number on the seal may find somebody else who is using the number that's on the seal for the same bearing you're looking for...
