They are available with either a single or double sealing lip.\r\n\r\nThe primary lip retains oil or grease around a rotating shaft to prevent lubricant loss, as rotating shafts often feature lubricant to reduce friction. In double lip designs, the secondary lip acts as an excluder to keep contaminants such as dust, moisture, and debris from entering the system. Oil seals for use on external applications are available upon request.\r\n\r\nSee\u00a0 our case study on how double lip oil seals combined with the appropriate sealing material improved an electric race car motor’s performance at high rotational speeds and temperatures: Improved Engine Performance with Double Lip Oil Seals<\/a>\r\n
