In addition to preventing oil leakage, oil seals for rotating shafts also help to keep out contaminants such as dirt, dust, and water. This is important for maintaining the cleanliness of the machinery and preventing damage to the moving parts. By creating a secure barrier against external elements, oil seals help to prolong the life of the machinery and reduce the need for maintenance and repairs.

Wheel bearing grease seals, often referred to simply as grease seals, are fitted between the stationary and rotating parts of a wheel bearing assembly. They create a barrier that prevents grease from leaking out while simultaneously keeping dirt, dust, moisture, and other contaminants at bay. Typically made from durable materials such as rubber or synthetic compounds, these seals are engineered to withstand high temperatures and pressures, which can occur during operation.
