Descriptions of oil seals

Oil Seals: Designed to aid trouble-free operation of your equipment, providing an excellent barrier against the escape of oils and greases and preventing the ingress of foreign matter.
Benefits: Excellent wear resistance, good running properties, high resistance to chemicals and petroleum based fuels including petrol, diesel and LPG.

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. This is mainly achieved by the sealing element. Nitrile Rubber (NBR)
NBR is the most commonly used seal material. It has good heat resistance properties, good resistance to oils, salt solutions, hydraulic oils, and gasoline. Operation temperatures are recommended from -40deg C to 120deg C. It also functions well under dry environment, but only for intermittent periods.

The TC Oil Seal is specifically designed to keep out water and dirt. The rubber coated outside diameter creates an optimum seal at the hub. The steel garter spring guarantees constant pressure on the axle shaft over the life of the seal. Great for replacing your damaged oil seal.

Construction The seal cases are made from SAE 1008-1010 Carbon Steel and are often coated in a very thin layer of Nitrile rubber to assist sealing in the housing. The principle function of the metal case is to impart rigidity and strength to the seal.
The spring is made from SAE 1050-1095 Carbon Spring Steel which has a protective zinc coating. The principle function of the spring is to maintain an even gripping pressure around the shaft

Resistance to temperature extremes:

Heat

withstands high temperature and simultaneously retains its good mechanical properties better than most other elastomers. Oil and chemical resistance also are relatively unaffected by elevated temperatures. Compounds of remain usefully elastic indefinitely when exposed to laboratory air oven aging up to 204°C (400°F) or to intermittent test exposures up to 260°C (500°F). High temperature service limits are generally considered to be:

3,000 hr. at 232°C (450°F)
1,000 hr. at 260°C (500°F)
240 hr. at 288°C (550°F)
48 hr. at 316°C (600°F)

Cold

1. is generally serviceable in dynamic applications down to -18° to -23°C (0° to -10°F), although special formulations permit its use in static applications down to -54°C (-65°F). Also, has proven to be satisfactory for static seals used under conditions approaching absolute zero.

2. Resistance to degradation by a greater variety of fluids and chemicals than any non-fluorinated elastomer, providing the best proven fluid resistance of any commercial rubber. Excellent resistance to oils, fuels, lubricants, and most mineral acids.

3. Extremely low permeability to a broad range of substances, including particularly good performance in oxygenated automotive fuels.

4. Resistance to many aliphatic and aromatic hydrocarbon fluids that act as solvents for other rubbers.

5. Exceptionally good resistance to compression set, even at temperatures which can embrittle other non-fluorinated elastomers.

6. Exceptionally good resistance to atmospheric oxidation, sun, and weather. Excellent resistance to fungus and mold.

7. Good electrical properties in low voltage, low frequency applications.

8. Low burning characteristics; inherently more resistant to burning than other non-fluorinated hydrocarbon rubbers.

Features of oil seals

Commonly known as an oil seal, shaft seal, or lip seal.

These are used to exclude dust, dirt and water on one side

whilst keeping the lubricant in on the other.

Generally they have been developed as a means of protecting the bearings

The most common Oil Seals are Double lipped which are R23 or TC

and Single Lipped which are R21 or SC
