Basic information:

Oil seal is often called grease, fluid, dirt or lip seals. Oil seal is an integral part in any rotating and moving part assembly. They close spaces between stationary and moving components in mechanical equipment. In most applications, the seal is either partially or temporarily immersed or is simply exposed to splashing lubricant, particularly in engines, transmissions, gearboxes or axles. They are vital components of almost every type of machine and vehicle in operation. An oil seal normally consists of three basic components: The Sealing Element (the nitrile rubber part), the Metal Case, and the Spring. It is a widely used sealing component. The function of a seal is to prevent the leakage of medium along the moving parts.

Oil seals are often called dirt, fluid, or grease seals, and they serve to close spaces between stationary and moving components within mechanical machinery. They are designed to prevent the escape of lubricant necessary for proper function. They also serve to keep various contaminants from entering machinery. Oil seals are used wherever shafts rotate and bearings require lubrication to work effectively. 

 

KDIK's National Oil Seal line of O-ring seal boast the coverage necessary for the gamut of popular applications. These handy oil seals serve to close spaces between stationary and moving components in mechanical equipment, also helping to prevent lubricant from escaping the system. They also serve to block harmful contaminants from entering machinery, especially within severe environments. National Oil Seals are great for thousands of applications across many different industries like automotive, manufacturing, power transmission, and more.

Advantages of National Oil Seal:

 

1.Rugged Durability: Oversized double-walled metal outer diameter helps prevent the seal from spinning or walking out of the hub bore (includes

black bore sealant).Heavy-duty construction enables effective heat transfer away from the sealing lip.

2. Extended Seal Life: Corrosion-proof spacers feature multiple vent holes,enabling the free flow of lubricant to the sealing lip to help extend service

life.

3. Innovative Protection: Unique contamination exclusion system utilizing three nitrile (NBR) lip contact barrier points helps prevent seal lip damage

and provides protection across a broad temperature range (-20ºF to 225ºF [-29ºC to 107ºC]).

4. Impressive Sealing: Wide shoulder coverage provides protection on worn or damaged axle shoulders.

5. Stronger Value: Meets or exceeds the performance of major industry competitors.

6. Simplified Installation: Steer, drive and trailer axle seals are available with tools designed to simplify accurate installation.

FAQ

 

What is the purpose of an oil seal?

An oil seal has three main functions&#; to prevent lubricants from leaking outside the seal even under high pressure, to serve as a barrier to retain lubrication material, and to prevent dirt and contaminants from entering the unit.

 

What types of oil seals are there?

There are many different types of oil seals including single and double lip, rubber or polymer, metal cased, spring loaded, and internal, external, and axial oriented.

 

What are the benefits of nitrile

rubber oil seals

? 

Oil seals made from nitrile rubber offer good heat resistance properties, and are also resistant to salt solutions, oils, hydraulic oils, and gasoline They also operate well in dry environments for intermittent periods.

How is an oil seal constructed? 

Oil seals generally consist of three basic components including the sealing element, the metal casing, and the garter spring.

 

Why do oil seals fail?

Severe cold can crack seals and cause them to fail. Other seals such as brake, transmission, and axle seals can be damaged due to extreme temperatures as well. Dirt and contaminants can also cause seals to slowly break down over time allowing for leaks and eventual failure.
