摘要： The bearing seal assembly (50) includes a metal shield (70) and a resilient multi-lip sealing gasket (60) secured to the metal shield. The metal shield is supported in use by an outer ring (20) of a rolling contact bearing and includes a diagonally extending central portion (72). The sealing gasket (60) provides a number of contacting lips (62-64) facing an inner ring of the rolling contact bearing. A first, main contacting lip (66) exerts a first radial load on the inner ring. A second contacting lip (62) extends from the first lip (66) and exerts a second radial load on the inner ring lower than the first radial load. A third contacting lip (64) is on the opposite side of the second lip (62) with respect to the first lip (66) and exerts a third radial load on the inner ring lower than the first radial load but greater than the second radial load.
