Abstract
A bearing seal is provided having inner and outer frames capable of forming a tight fit with a bearing inner ring and with a bearing outer ring respectively. The frames adjacent to each other, at least one of the two formed with an axial lip abutting an inner surface of the other in an axial direction and a radial lip abutting an inner surface of the other in a radial direction, for sealing an axial gap and a radial gap. A flexible convolute structure formed on the radial lip, and the convolute structure is initially formed with at least two hinge points. The hinge points are points of connection and intersection between adjacent bend surfaces in the convolute structure, being the locations of the principal regions where the material actually deforms by bending between adjacent bend surfaces. Predetermined bend angles are formed at the hinge points between adjacent bend surfaces.
