Oil seals

Of all the types of rotary shaft seals, oil seals, also referred to as Viton oil seals, are the best known. Contrary to what the name suggests, a oil seal is also often used in applications involving a medium other than oil. These seals are sometimes called Simmering seals, based on a brand name used by Freudenberg.

When purchasing a oil seal, you must always consider the shape and size, and the material used for the product.

Types of oil seal

Most oil seals are designed in accordance with the DIN 3760 standard. This standard includes several models. For example, there are oil seals with and without a dust sealing lip. A dust sealing lip prevents dirt ingress from the outside. A useful feature as it reduces contamination in your application, which in turn results in a longer service life.

Our range includes oil seals in various sizes. Always keep in mind the dimensions of the groove where you will install the oil seal. Once you know the shaft diameter, groove diameter and groove width, you can easily select the right product.

Lip materials

Most oil seals consist of (1) an outer metal jacket, or a metal insert inside a rubber jacket, and a sealing lip. The metal outer jacket or insert acts as a base and determines the shape and size of the product. In most cases, the sealing lip and the jacket or insert are made of different materials. A brief summary of the most popular lip materials and their properties is included below.
