Abstract:
A torque-resistant dual face seal includes a seal ring having an L-shaped cross-section including an axially-extending flange and a radially-extending flange, the seal ring including an annular seal face and an opposing loading surface. The seal ring includes a plurality of deformations formed in a spaced apart arrangement circumferentially around the axially-extending flange. An axial cross-section through the axially-extending flange and intersecting one of the plurality of deformations includes a stepped geometry. The plurality of deformations allows a load ring to squeeze into the plurality of deformations to increase a surface area contact between the seal ring and the load ring.
