<p>A rotary seal for dynamically sealing against a surface of a shaft includes a seal body having a sealing surface and an outer surface. The sealing surface has a fir st side edge and a second side edge. The sealing surface has discrete fluid pockets positioned between the first side edge and the second side edge. The discrete fluid pockets trap and use clean lubricating fluid to provide a hydrodynamic film between the seal surface and rotating shaft.</p> |
