Conventional oil seals are the traditional seals, which can be recognised by a spring on the inside. These oil seals are made of a metal housing that contains a rubber seal. This part is often made of elastomer and comes into contact with the surface of the rotating shaft.
Multiple materials and compounds are used to make oil seals. Some of the oldest materials still used today include felt and leather compounds. However, the trend in mass production has experienced a shift towards synthetic elastomers or rubber.
