Timken 12S42500 Commercial Vehicle Standard Seal

Oversized double-walled metal outer diameter helps prevent the seal from spinning or walking out of the hub bore. Heavy-duty construction of outer wall enables effective heat transfer away from the sealing lip. Unique contaminant exclusion system utilizing three nitrile lip contact barrier points helps prevent seal lip damage and provides protection across a broad temperature range (-20F to 225F / -29C to 107C). Corrosion-proof spacers feature multiple vent holes, enabling the free flow of lubricant to sealing lip to help extend service life. Wide shoulder coverage provides protection on worn or damaged axle shoulders.
