Abstract
A face seal assembly for a gas turbine engine includes a seal body having a seal face defining a contact area disposed between tapered sides. The seal body defines an axial width between a back surface of the seal body and the seal face. A decrease in the axial width from wear increases the contact area. A bearing assembly and method are also disclosed.
