Claim:
A seal ( 2 ) for a bearing ( 6 ) that rotatably supports a shaft ( 14 ) extending through a housing opening ( 8 ) of a housing element ( 10 ) that limits, at least partially, a lubricant-receiving chamber ( 4 ), the seal comprising a sealing disc ( 26 ) retainable between the housing element ( 10 ) and the shaft ( 14 ); and a limiting element ( 28 ) forming, together with sealing disc ( 26 ), an annular gap ( 30 ), the sealing disc ( 26 ) having aeration recesses ( 34 ) which connect the annular gap ( 30 ) with the lubricant-receiving chamber ( 4 ), wherein the sealing disc ( 26 ) is formed by an impeller-like disc connectable with the shaft ( 14 ) for a joint rotation therewith, and wherein the limiting element ( 28 ) is fixedly connected with the housing element ( 10 ), wherein the annular gap ( 30 ) is formed between a radially outer rotational surface ( 32 ) of the sealing disc ( 26 ) and the limiting element ( 28 ), wherein the aeration recesses ( 34 ) open into the rotational surface ( 32 ) of the sealing disc ( 26 ), and wherein the aeration recesses ( 34 ) are substantially identical and are spaced from each other by a same angular distance (α).
