Description auto oil seals and Grease Seals Information
auto oil seals and grease seals have a flexible lip that rubs against a shaft or housing to prevent the leakage or ingress of fluids and dirt.
For proper installation, the seal lip should point towards the medium being contained. Some auto oil seals and grease seals have a spring to help keep the lip in contact with the shaft.
Oil and grease seals are used to retain or separate lubricants or fluids. These seals are primarily used for rotary applications only.
auto oil seals and Grease Seals Information Types
The seal type for oil seals and grease seals can be auto oil seals or other types. An oil seal can also called flexible lip, radial lip, or rotary shaft seal. Common configurations include single lip, double lip, triple lip, and four or more lips. rubber sealing.
Bearing Isolator
Bearing isolators are dynamic seals designed to protect bearings from outside contaminants. They are comprised of a rotor (rotating) and stator (stationary) member. Some bearing isolators are of labyrinth construction while others use O-rings or other positive seals.ring seal.
Other types of auto oil seals and grease seals include:
Metal cased
All rubber or polymer
Internal orientation
External orientation
Axial orientation
Spring-energized

The sealing orientation and direction is important to consider for auto oil seals and grease seals.Description auto oil seals Grease Seals Information.nok seal.
Rod seals, also referred to as shaft seals, are radial seals. The seal is press-fit into a housing bore with the sealing lip contacting the shaft.
Piston seals are radial seals. The seal is fit onto a shaft with the sealing lip contacting the housing bore. V-rings are considered external lip seals.
A symmetric seal is symmetrical and works equally well as a rod or a piston seal.Description auto oil seals Grease Seals Information.
An axial seal seals axially against a housing or machine component.
