There are a variety of oil seals used in a variety of applications to help close the space between a stationary and a moving part. By closing the space it prevents any lubricants from escaping. Additionally, oil seals help create a seal that prevents any contaminants from entering machinery which can cause a host of problems. Mechanical equipment and machinery require different size or type oil seals to ensure that there is a superior and precise seal. Because oil seals help reduce contamination or mixing of materials it prolongs the life of machinery and helps ensure a more reliable performance.

The sizes of industrial oil seals typically range from 0–33cm. These varieties are designed for temperature fluctuations. If your seal matches the intended equipment, the machine will perform optimally.

Purpose of an Oil Seal

Rotary shaft or oil seals are placed between moving and stationary pieces of machinery to ensure that contaminants, moisture, corrosive materials and abrasives do not damage the various components. They can also prevent unwanted mixing of fluids, including water and oil combining within a machine.
The major cause of extrusion and nibbling is stress caused by high pressure. This is commonly noticed when the oil seal has a chipped or nibbled look. In fact, in some cases, the surface of the seal tends to peel on its own, which makes it have a shaved look. What the stress does is that it increases the clearance gap between the mating edges, which causes the seal to get entrapped, and then leads to severe physical damage.
The basic principle of sealing is straightforward – the flexible lip is held against the rotating part (usually the shaft) whilst the casing (or O.D.) is pressed into the housing or bore and holds the seal in place. The sealing lip needs some form of lubrication to avoid overheating and is usually energized by means of a garter spring.
The seal shown in Fig. 14.2 is a relatively simple design; most automotive seals are more complex. Dust lips are often used to keep outside contaminants away from the oil lip seals; such seals thus have undercuts that make demolding more difficult. Fluoroelastomer compounds used for such undercut shapes must have reasonably high elongation at break at molding temperatures to avoid tearing the part during demolding. The metal insert is often U-shaped, and stock may be molded to form a thin layer over the outside of the insert. Since both compression and injection molding methods are used, suppliers of fluoroelastomers for shaft-seal applications often must provide different versions of the same polymer composition-medium to high viscosity for compression molding, and low to medium viscosity for injection molding. Different precompounds may be necessary to accommodate relatively long compression-molding times at low temperature and very short injection-molding times at high temperature.

Fundamental things and its importance
In this post, we’ll go over the fundamental things you need to know as a DIYer when working with oil seals.
HID (High Intensity Discharge)
Generally, an oil seal is made up of an outer circular metal part and a bonded inner flexible material (often nitrile rubber) that does the actual sealing.
Sealing process

In addition to these standardised types, the following special types are also available:
What are Oil Seals and how should they be ordered?
Out of all of the elastomers, silicone offers you the widest range of working temperature ranges. Renowned for its flexibility and low compression set capabilities, silicone is the optimal choice for o rings and other moulded seals.

rotary shaft oil seal. It is important to choose a high-quality seal that is compatible with the requirements of the system to ensure optimal performance and longevity.
Choosing the wrong materials for an oil seal may result in premature wear, lip hardening, cracks, swelling, and subsequent expensive damage to the machinery in which the seal is used. It is therefore vital to gather all relevant data and consult with experts before purchasing to match the right type of oil seal with your application.
