Oil seals are called rotary shaft seal or radial lip also.
A wide range of industries rely on oil seals to ensure optimal operation of mechanical assemblies. Components in the industrial and automotive fields, such as pumps, fans, electric motors, and other rotating or moving parts, use oil seals to maintain lubrication and keep contaminants from entering the shaft. Seals are especially useful in applications exposed to extreme environmental temperatures and pressures.
3. Seal types and numbering system
Unthinkable in the list of seals are oil seals, which provide a seal against splashing oil. The most important oil seals are used for rotating shafts and valve stem seals. Oil seals are intentionally never completely sealed to lubricate the seals and prevent wear.
There are four general motor oil types:
Its sealing edge comes in full contact with the shaft surface in order to provide excellent sealing performance.
(See Figure 3.)

The simplest way is to know either the preferred manufacturers part number, the overall sizes of shaft diameter, housing diameter and bore depth.Many of the old traditional names of seal manufacturers have either changed or disappeared in this age of “acquisitions”. If no longer available, we will advise you and offer a suitable alternative seal, from stock whenever possible. If your concern is getting the right seals for the job, you will need to know something about the application as well as the overall sizes. If you have any doubts – contact us, we will help in your seal selection.
