While there are several variations, the two most frequent types defined in the standard are:

Combines the rigid fit of the Type B design with the exclusion capabilities of the dust lip. Type C (Reinforced Metal Casing)

A tension spring that ensures the sealing lip maintains constant pressure against the rotating shaft. Common Design Types din 3760 pdf

Similar to Type B, this variant features a metallic outer diameter paired with an integrated dust lip for enhanced protection against harsh environment contaminants. Type C (Form C)

If you work in mechanical engineering, automotive design, or maintenance, you have likely encountered the term . It is one of the most referenced standards for rotary shaft seals—critical components that keep oil in and contaminants out of machinery.
