High-Pressure Rotary seals that are used for high-pressure applications have a solid cross-section, are developed to seal a pressurized lubricant, and possess hydrodynamic waves that encounter the pressurized lubricant. These fluid waves pump lubricant into the engaged sealing interface when the shaft spins.

An oil seal is designed to perform three major functions: to prevent lubricants from leaking outside the seal even under high pressure, to act as a barrier to retain the lubricating oil, and to prevent dirt and other contaminants from entering the unit.

The oil seal is generally composed of three basic components: sealing element, metal shell and clamping spring.Types of oil seals include single and double lips, rubber or polymer, metal housing, spring loaded, and internal, external and axial guides.

Oil Seals which are also known as rotary shaft seals are used to prevent lubricants from leaking and escaping. They protect key components of the machinery from being damaged from various fluids, dirt and dust from getting inside the machines. Oil Seals are a vital component in preventing harmful interactions between moving and static parts. Without using them you could cause expensive damage and halt whole operations. Using our 6 Guidelines for oil seals will help your buying decision. You can read about the different Oil Seals we stock here.

Oil seals close spaces between fixed and moving parts and protect all kinds of ball and roller bearings. They keep rotating shafts and bearings from pollution and corrosive materials, and also prevent lubricants, oils, and liquids from leakage. An oil seal can have a single lip, double lip and even triple lip, so single lip seal is one lip to seal around the shaft, double lip seal is two lips sealing around this, and triple lip seals have three lips to seal.

The skeleton oil seal is a typical representative of the oil seal. Generally speaking, the oil seal refers to the skeleton oil seal. The function of the oil seal is generally to isolate the parts that need to be lubricated in the transmission parts from the output parts, so as not to allow the leakage of lubricating oil. The skeleton is like the steel bars in the concrete member, which acts as a reinforcement and enables the oil seal to maintain its shape and tension.

Acrylate-natural rubber is its excellent heat and hot oil resistance. ACM is resistant to motor oils with modern additives, gearbox oil, lubricants etc. In addition there is the high oxidation and ozone resistance of a saturated polymer chain. Temperature range from -20 °C to +175°C.

Seals are essential to protecting the bearings of any rotating shaft assembly -They prevent contaminants such as dirt, dust and water, while also preserving the system’s lubricant.

A standard oil seal consists of an outer circular metal disk with an inner flexible rubber which is affixed to the metal during vulcanization. The bonded seal has no loose parts to allow leakage of oil or ingress of any contaminants. This kind of seal is more accurate, and can easily be fitted into a smaller space. An example is shown in Figure 2.9.
