Read ReviewsThe sealing part, the metal case, and the spring are the standard three parts of an oil seal. The sealing component aims to prevent fluid leakage between the shaft and housing. The metal case will offer stiffness and strength as the seal is retained in the bore or recessed groove. The garter spring maintains radial force on the shaft and constant pressure, flattening the sealing edge to a specified width. In addition, the garter spring maintains the sealing lip's radial force around the shaft surface. The environment the oil seal will operate must be considered when choosing any material.
An appropriate unit load must be kept at the seal-shaft interface for these seals to work as intended. These seals can withstand 15 psi of pressure, and their performance is influenced by factors such as shaft diameter, speed, operating temperature, service circumstances, etc. Any rotating and moving parts combination must include oil or shaft seals. Oil seals are widespread in hydraulic cylinders, gearboxes, etc. The seals are also known as "dynamic oil seals" since they are used in places where motion is an issue.
Along with the standard sealing lip, this also has an auxiliary lip. This type is advised for usage in polluted areas because the additional dust lip shields the main sealing lip from dust and other fine solid pollutants. Again, a sufficient lubricant should be used between the two sealing lips to achieve a long lifespan.
Occasionally, two distinct fluids will mix after leaking from one chamber to another. This kind is advantageous in this case. This duplex-type oil seal with metal inserts is suggested for use on assemblies where it's important to avoid mixing different fluids.
This kind of oil seal may tolerate only very little speed and friction. It is advised in locations that must be sealed off from thick fluid or grease. For challenging applications, this is not advised.
Nitrile synthetic rubber is used to make oil seals, and steel stiffener rings are used. Other rubbers like Viton™, silicon, neoprene, or poly acrylic can be utilized for particular uses. For example, brass or stainless steel stiffener rings may be used when sealing extremely corrosive fluids. For corrosion resistance, most springs are composed of spring steel that meets IS 4454:Gr.ll standards, stainless steel, or bronze.
The interference fit between the flexible sealing element, often strengthened by spring pressure, and a shaft leads to the sealing of lip-type seals in most cases. Fluid retention is determined based on the precise amount of lip contact pressure. Most lip seals experience increased lip contact pressure on the shaft due to higher fluid pressure in the sealed area.
Metal-cased oil seals are used when affixed to a housing bore of the same material. Due to the materials' ability to operate with equal levels of contraction and expansion, leakage is prevented. Generally speaking, rubber seals cost more than metal-cased seals.
Rubber-cased oil seals are the most widely used oil seal implementation when a metal-cased oil seal has a probability of failing (for example, because of thermal expansion). In contrast to oil seals with metal casings, rubber-cased oil seals cannot rust. Additionally, oil seals with rubber cases are much more effective in sealing a housing with little damage than oil seals with metal cases. Fast-expanding rubber can provide a tight fit and more stable sealability at high temperatures and pressures.
The one that is used frequently is Type R. This kind has a carbon steel insert and a rubber outside diameter. Rubber has a great sealing ability even if the housing is not entirely within tolerance. The sealing lip with spring produces obstruction on the shaft for effective sealing. The outside diameter and inner metal reinforcement casing enable press-fitting in the housing with adequate interference on the rubber to ensure static sealing.
The sealing part is made out of nitrile rubber. Thanks to this and a high-quality galvanized steel garter spring, this oil seal has the longest lifespan conceivable. To prevent leaks brought on by a hydrodynamic pumping action, the sealing lip contact area on the sleeve or shaft must be devoid of any indications of machine life.
Type “B” oil seals resemble an "A" style seal. But, on the other hand, this has a metal case outside. This type is preferred with rugged housing, hot environments, and demanding jobs.
The outer layer of the skin often varies depending on how the oil seal is applied. Here are some materials used to make this oil seal's exterior skin.
Several conditions must be met for the oil seals to function properly. These factors are:
