These seals are designed to fit snugly around the shaft of the machine, preventing oil from leaking out while also keeping dirt, dust, and other contaminants from entering.
The healthcare sector benefits from the antimicrobial properties of some specialized white rubber formulations. In hospitals and clinics, gaskets are used in medical equipment to prevent contamination and maintain sterile environments. Their non-porous surface inhibits the growth of bacteria and makes cleaning and disinfection easier. The composition of nitrile rubber, which is a blend of acrylonitrile and butadiene, gives it its unique properties. The percentage of acrylonitrile (nitrile) in the compound determines the oil resistance and temperature range of the seal. A higher nitrile content generally indicates better resistance to oils and solvents, while a lower content provides better flexibility at low temperatures. For instance, a nitrile oil seal with 50% nitrile content is suitable for general-purpose applications, while seals with 70-90% nitrile content are specifically designed for high-temperature and oil-resistant environments.
JTEKT provides special seals for use in a wide variety of machines and applications.
Table 5 lists the major special seals, their shapes, and their features.
Oil seals or shaft seals are an integral part in any rotating and moving part assembly. Oil seals find great deal of usage in gearboxes, hydraulic cylinders, etc. The usage of the seals in areas concerned with motion also earns them a name of “Dynamic Oil Seals.”
Shaft oil seals are used in a wide range of industries, including automotive, industrial, and aerospace
. In automotive applications, they are commonly used in engine crankshafts, camshafts, and differentials, where they help to prevent oil leaks and maintain optimal lubrication levels. In industrial applications, shaft oil seals are used in pumps, compressors, and other rotating equipment to protect bearings and other critical components from damage.The range of uses of peroxydically cross-linked EPDM includes in hot water and steam seals. EPDM is also very resistant to ageing and ozone. Compared with the usual types of synthesis natural rubber it has good resistance to cold temperatures. EPDM is not resistant to aliphatic or aromatic hydrocarbons or mineral oil products. Resistance to chemicals, and also to oxidising agents, is very good. Temperature range from -50 °C to +140 °C depending on type.
A loose or missing valve cover gasket bolt can lead to a variety of issues. An oil leak can contaminate the spark plugs, affect the air-fuel ratio, and lead to misfires. Moreover, leaked oil can pool on hot engine parts, posing a fire hazard Moreover, leaked oil can pool on hot engine parts, posing a fire hazard
