GENERAL INFORMATION
Oil seals are employed for sealing rotating shafts. They are manufactured in a wide range of forms and materials, depending on working conditions. In this catalogue, you will find our standard range of oil seals, although other sizes, designs or materials can be supplied if the quantities justify it.
The basic design of an oil seal comprises a metal frame A which gives some consistence and allows assembly and fixing. The closing lip B is the only part subjected to relative movements and, therefore, subject to wear. Spring C which provides a constant force between lip and shaft. And finally a membrane D, which is the most important element in the assembly, since all rotating shafts have to cope with small but constant vibrations.Once the right contact pressure is achieved between the lip and the shaft, through the spring that allows the development of a lubricant film, these vibrations can increase the thickness of this film up to such degree that oil leakage occurs.
(fig.1)
The only way to avoid this leakage is trying to maintain the film thickness more or less constant, which means that the membrane has to be sensitive enough to “accompany” the vibrating shaft.
DEVELOPMENT OF LUBRICANT FILM
The lubricant film develops a few seconds after work has started as a capillarity effect but it may not occur if the shaft surface or the pressure of the seal is inadequate.

TEMPERATURE INCREASE ON THE LIP
Due to friction, the temperature in the lower area of the lip increases.This increase can have a negative effect on the life of the seal as it can wear the seal material quickly. In this case, the oil dissipates the heat and reduces the heat leap between the area on the lip and the temperature of the rest of the oil.For this reason the properties of the fluid as well as the quantity in contact with the seal are very important. In you will see the temperature increase under the lip with respect to the overall temperature and depending on the shaft diameter at a speed of 3000 rpm.It also shows what influence the lubricant type and quantity have over this increase.

In both areas the upper curve indicates the value when the oil level just gets to the shaft, and the lower curve, when the seal is totally dipped in oil. You will also see the temperature increase with respect to the shaft diameter and speed. (figure B).
THE SHAFT
Material, finishes and tolerances
The best shaft materials are steel or cast iron, with a surface hardness of 50 HRC or higher. For special applications hard chrome plating or ceramic sleeves can be employed. Machining is done through front feeding. Surface finish must be Ra 0,2 - 0,8 µm.Recommended shaft tolerance ISO h11 (see table)

For easier assembly and in order to avoid damage to the seal, shafts should have the following chamfers.

The shaft should rotate concentrically with respect to the housing. The following graphic shows the maximum value of shaft runout the oil seal can withstand at different speeds.

In order to assure a good performance of the seal the following details should be observed:
ASSEMBLY
The side where the spring is installed normally faces the oil to be sealed.
Check the shaft and eliminate any roughness, remains from machining, as well as any surface impurities. Sharp edges must be rounded or chamfered. If this is not possible, a sleeve with rounded edges and a slightly bigger diameter than that of the shaft must be provided. Any small cut in the sealing lip during assem-bly will cause leakage.
When installing the seal into its housing a uniform pressure must be applied all around. Also make sure to install the seal in a perfectly perpendicular position to the shaft.
Assembly tools of the types shown in are recommended. The outer diameter of
the tool must be a little smaller than the housing diameter (0,1 to 0,4 mm ).
The outer diameter of the seal must be greased before installation.

Before installation make sure seals are clean and in good condition.
Apply grease to the sealing lip. If it also has a dust lip, apply grease between both lips.
Check the proper installation of the spring into the housing.
