An Oil Seal (also known as a Shaft Seal, Lip Seal or Elastomeric Lip Seal), is a simple device for excluding dust, dirt, water or any other contaminant whilst retaining lubricant in rotary shaft equipment. Generally, Oil Seals have been developed as a means of protecting the bearings of rotating shafts.
R21 Oil Seals have a metal body which is rubber coated and contains a single sprung lip. R23 Oil Seals have an extra lip called a 'Wiper Lip', and are sometimes referred to as 'Double Lip'.

The rotary shaft seal(pictured) is constructed with a metal casing which is coved in a rubber material and can be used on any size of shaft.
The rubber covering prevents the mental casing from rusting and helps prevent damage to the housing during assembly.
This &#;standard&#; rotary shaft seal comes either in single or double lipped style. The single lip seal (SC/R21 or VC/R26) seals against internal media whereas the double lipped seal (TC/R23 or KC) seals against the internal media and offers an auxiliary lip which provides protection against dirt and dust.

The DC/R22 style rotary shaft seal is a double lipped and double sprung seal. This style offers a seal against two medias. It&#;s as simple as that!
The VC/R26 and KC style rotary shaft seal have the same lip features as the SC/R21 and TC/R23 styles but do not contain a garter spring.
This design is often used where space is at a premium or when a low friction application is required.
