Abstract
A bearing seal assembly is provided for sealing a sealing gap defined by a first race and a second race of a bearing. The bearing seal assembly includes a resilient seal having a cross-sectional profile, wherein the profile defines a flexing portion, and the resilient seal further has a first pressure-bearing side and a second side opposite the first pressure-bearing side. The flexing portion is configured to flex to form an energized seal that seals the sealing gap when a pressure is applied to the first side of the resilient seal, wherein the cross-sectional profile is symmetric about a horizontal axis and asymmetric about a vertical axis. The cross-sectional profile specifically may be a K-shaped profile, and the flexing portion comprises arms defined by the K-shaped profile. The assembly may include a wear strip section positioned outside of the profile of the resilient seal, with a removable blast shield.
