Metal O.D. wall type Ensures improved fitting retention between the seal O.D. and the housing bore.
The selection of the right high pressure oil seal is critical

• High eccentricity-following lip shape

Next comes the molding stage. The cured rubber is placed into a mold that corresponds to the specific shape of the oil seal. The mold is closed and subjected to high pressure and temperature, causing the rubber to take on the mold's shape. For seals with metal components, these are either pre-inserted into the mold or added later through a bonding process For seals with metal components, these are either pre-inserted into the mold or added later through a bonding process

Meanwhile, rubber-cased oil seals are used under conditions where a metal-cased seal can fail (for example, because of thermal expansion). Unlike the metal-cased type, these seals do not rust. Moreover, they can seal a lightly damaged housing better than metal-covered seals since, in high temperatures, rubber can provide a more stable sealability.
Nitrile oil seals offer several advantages over other types of seals. Their excellent resistance to hydrocarbons, such as gasoline, diesel, and lubricating oils, makes them ideal for automotive engines and transmission systems. Moreover, they exhibit good compression set resistance, ensuring a long-lasting seal even under constant pressure. Their ability to maintain their integrity in both cold and hot conditions further enhances their versatility.

Oil seals go by many names, such as shaft seals, dirt seals, grease seals, lip seals, and many other variations of these. They are essentially simple devices used in rotary shaft equipment to prevent lubricant from escaping and for excluding contaminants such as dust, dirt and water. An oil seal’s most important function, however, is that it protects every type of ball, sleeve and roller bearing in the rotating shafts. The seals also prevent the integration of two different fluids that shouldn’t mix, such as oil and water.
