I am not sure of your application, but if it is an open driveshaft, the answer is yes. The bearing retainer holds the seal, there is also a piece of felt (never have found replacements for the felt so don't mess it up) trapped between the flange and seal to catch the heavy debris. The original seal is fairly stout and will take considerable coercion to drive out. Make certain to use a sealant on the outside of the new seal where it mates to the flange.
