Purpose of the Metal Plate on Unitized Trailer Hub Grease Seals
Updated 10/28/2015 | Published 10/27/2015
Question:
I would like to know why your 10-63 unitized seal for dexter axles have an extra piece of metal or metal washer on the inside side of seal? Dexter does not have this on the inside, it is an open seal. Is this better or what and why. Can not find any information on the web about either way.

Expert Reply:
The unitized seal part # 10-63 has a metal plate that attaches and stays fixed to the spindle and the outer rubber piece will rotate with the hub. This is the kind of seal that is used on oil bat hubs and this particular one is for 8k rated Dexter hubs.
