Abstract
A seal case for a bearing seal includes (a) an inner case encircling a rotation axis of the bearing seal, (b) an outer case encircling the rotation axis and including a ring-shaped frame and a rubber gasket over-molded on the frame, and (c) a plastic wafer clamped between the inner case and the outer case, and secured at least by the rubber gasket. A method for manufacturing a bearing seal includes over-molding a rubber gasket onto a ring-shaped frame to form an outer case, placing a plastic wafer between the rubber gasket and an inner case, and securing the inner case to the outer case to form a seal case.
