Rotary Shaft Sealing

Rotary shaft seals are typically used to seal a rotating shaft or rod and are designed to protect bearings and internal components from dirt, water and other media that might cause premature failure of the equipment. These seals also play the important role in retaining the bearing lubricant. The different sealing arrangements can be found in washing machines, industrial gear boxes, electric motors, pumps, wind turbines, automotive components, hydraulic systems and many other applications.

The most common types of rotary shaft seals are; oil seals, grease seals, lip seals, bearing seals, labyrinth seals and v-seals or v-rings. Depending on the application, a radial shaft seal can be rubber encased or metal encased, with different lip styles and elastomer types.

The outside lip is called a dust lip and inside lip (with spring) is the sealing lip. The extra dust lip helps prevent contaminants from getting to the sealing lip and in turn extends the life of the system it is protecting.

Oil Seal Installation

When installing an Oil Seal, lead-in chamfers or round edges should be used on the shaft to avoid damage to the sealing lips. A thin protective sleeve made of plastic or aluminum can be used to assist. Use a press or clamp to ensure a uniform load on the seal.
