A seal includes an at least partially cylindrical annular body defining a radial direction, an axial direction, and a circumferential direction. The at least partially cylindrical annular body has a radially outer flange, a radially inner ring, and a resilient intermediate portion joining the radially outer flange to the radially inner ring. The radially outer flange defines a seal outer diameter and a flange axial thickness, and a ratio of the seal outer diameter to the flange axial thickness ranges from 14.0 to 15.0.
