Abstract
A sealing system is provided with a construction which permits easy mounting in a bearing assembly, and which provides improved sealing functions by enhancing the ability to engage in a groove in the bearing assembly. The sealing system comprises a sealing device including a supplemental metal ring having a portion folded-over into a U-shape and a marginal end portion extending from the folded-over portion also folded-over into a funnel shape. When the sealing device is mounted in the bearing assembly, the marginal end portion may be expanded deformably to a greater diameter, to thereby allow it to engage in the groove and secure the sealing device in position in the bearing assembly.
