Y-ring is divided into several categories?Y-shaped ring of the Y-shaped cross section, which is a typical lip seals.Their section and high aspect ratio, wide, narrow, Yx type can be divided into several categories; Two lip height are equal, can be divided into the shaft holes universal type Y-shaped contour lip contour lip seals and shaft seals and holes of the Y-shaped with a Y-shaped ring. Y-ring so special?Y-ring characteristics can be summarized as follows:1) reliable sealing performance2) small friction, smooth motion.3) the pressure is good, use a wide range of pressure.4) The structure is simple and inexpensive.5) ease of installation. Scope of the use of the Y-shaped ring?Y-ring seals are widely used in reciprocating seals, its service life is higher than the O-ring.  working pressure: ≤40MPa; working temperature : -30 to 80 ℃;Operating speed range: used for the production of nitrile rubber is 0. 01 ~ 0. 6m s

The [DIN 3771" standard for O-rings is produced by the Duetsches Institut für Normung (German Institute for Standards). The [DIN 3771" specification describes 258 O-rings. Each size is designated by the ID × cross-section. Optionally, this designation may be followed by a letter indicating the quality level ([N" - normal quality; [S" - special quality. Subsequent to the letter indicating the quality level, the rubber polymer and IRHD hardness may be specified. In contrast to the AS 568 A inch system, the nominal and physical dimensions of metric O-rings match precisely. That is, a 1 mm O-ring will have a cross-section of 1 mm. The space that is being filled must be about 10% to 15% smaller than the cross-section of the O-ring in order for O-ring to seal properly.

A silicone O ring offers excellent resistance to extreme temperatures, ranging from -150°F to +500°F, for various sealing applications. However, its poor tensile strength and susceptibility to tearing and abrasions, has made it unsuitable for dynamic sealing applications.

X-Rings have a double sealing function as compared to an O-ring and can be used in a wide variety of static and dynamic sealing applications.The four-lobed design provides twice the sealing surface in comparison to a standard o-ring. The double-seal action requires less squeeze to maintain an effective seal. This reduction in squeeze means less friction and improved seal life.Additionally, X-Ring parting lines are between the lobes, away from the sealing surface. This eliminates the issue of leakage often resulting from a parting line`s irregular surface as found on an O-Ring. X-Rings are also designed to outperform a standard O-Ring in rotary seal applications. The four-lobed configuration creates a more stable seal to avoid spiral twisting. This allows the use of a narrower groove width than a standard O-Ring groove, but can also be used in a standard O-Ring groove. Advantages of X-Rings vs. O-Rings:·Avoid twisting in the groove. The seal does not tend to roll in the groove during reciprocating movement.·Low friction. It requires less radial squeeze than a comparable O-ring.·Less friction means less wear, and thus a longer service life.·Very good sealing efficiency due to it special profile.·A lubricant reservoir formed between the sealing lips improves start upw

They also stop harmful contaminants from entering machinery, particularly in severe environments. Vital components of practically every type of machine and vehicle in operation, oil seals protect all types of precision-constructed, close-fitting ball, sleeve and roller bearings. In precision bearings, oil seals help prevent lubricants from escaping the bearings or a specific area. In machine components, oil seals help prevent abrasives, corrosive moisture and other harmful contaminants from entering machinery.

Material DescriptionNitrile rubber (NBR), also known as Buna N, is one of the most commonly used sealing elastomers due to its resistance to petroleum-based fuels and lubricants and its relatively low price. Nitrile elastomers are copolymers of acrylonitrile and butadiene. There are a number of common variations of nitrile compounds.Acrylonitrile ContentThe acrylonitrile (ACN) content of the polymer chains can vary from 18% to 50%. Lower ACN content gives better low-temperature properties but inferior resistance to fuels and polar lubricants. Higher ACN content gives lesser quality low-temperature properties but improved fuels and polar lubricants resistance. Standard NBR typically have 34% ACN content.Temperature Range:Standard Low Temp: -40°C (-40°F) Standard High Temp: 100°C (212°F).

An SC type 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 petrol, diesel and other gasoline products. Operation temperatures are recommended from -40deg C to 120℃. It also functions well under dry environment, but only for intermittent periods. Cross section of an R21 SC style oil seal.

Oil seal consists of three parts: the seal body, strengthen the skeleton and the self-tightening spiral springs.The role of oil seal of the transmission components in general is in need lubrication components and parts output isolation, and typically used for rotating shaft is a rotary shaft lip seal. It can be divided in the seal, the outer seal, the inner and outer exposed skeleton oil seal. VBG type oil seal characteristic:Lip ring with spiral spring for radial preloading. Interference fit on outer diameter. Cut sealing edge for high dynamic sealing effect. Elastomeric outer case for high static sealing effect. An additional protective lip(dirt lip) prevents intrusion of dirt particles and thus increases functional reliability. Easy installation. For use in extremely dirty ambient conditions, we recommend our special VY design with two dust lips. Range of application Primarily for sealing oil- and grease-lubricated shaft ducts with little exposure to external(ambient) dirt.
