Abstract
A shaft seal 10 and method for sealing fluids in applications with excessive shaft-to-bore misalignment or dynamic shaft runout, including a seal 10 having a mounting section 22, a sealing element 24, and a convoluted flex section 26 which allows radial movement of the sealing element. The sealing element 24 includes a bearing member 42 having a liner 46 with a low friction, cylindrical bearing surface adjacent the lip 38, for causing the lip 38 to follow any radial movement of the shaft, and to prevent the lip 38 from taking an oval shape and leaking.
