Abstract
An apparatus has: a first member (); a shaft () rotatable relative to the first member about an axis; and a seal system (). The seal system has a seal carrier () having: an axially-extending wall () having an inner diameter (ID) surface (); and a radially-extending wall () having a first surface (). A seal () is carried by the first member and has: an outer diameter (OD) surface (); and a seal face (). A seat () is carried by the shaft and has a seat face () in sliding sealing engagement with the seal face. One or more springs () bias the seal carrier relative to the first member so as to bias the seal face against the seat face. A key () spans an interface between the seal carrier and the seal.
