Seals are an essential component of any machine that utilises rotary shaft equipment. At their most basic, a seal is a straightforward device that excludes dirt, water, dust and other contaminants while retaining the lubricant that is critical for the efficient operation of the shaft. Thus, various types of industrial seal have been developed to protect rotary shafts and their bearings, reducing the number of machine faults and extending the life of manufacturing equipment.

In industry jargon, rotary shaft seals are also known as oil seals, shaft seals and elastomer lip seals.
