It is used in wheel seal applications and is frequently used in centrifuges. Applications: FKM Fluorocarbon oil seals distinguish a great resistance to solvents and petroleum oils. Oil and Gas Seals Explosive Decompression Resistant O-rings (Norsok M-710 Seals, NACE TM0297 Seals) Automotive Fuel and Oil Seals Military Applications (MIL Spec Compliant Seals) Good Wear Resistance Good Compression Set Resistance Good Short-Term Resilience Good Permeation Resistance : Viton® (Fluorocarbon Type A) Order O-rings Online What are Oil Seals? between the sealing lip and the dust lip may also be filled See the range. Applications are the same as type RST, when the requested type is not available. This type is frequently replaced by type R. According to the DIN Standard 3760, category B, Similar to type M but with additional dust lip. It minimizes wear and friction in certain applications. The support ring is used to prevent the seal ring from being deformed under pressure. Prevent damage to your O-ring from improper use. In exceptional cases, it is also used to seal other fluids, gases and powdered or granular solids. What are Oil Seals – A guide to Oil and Rotary Shaft Seals. The gasket material fills the imperfections of the metal surfaces. Engineers Hub; Register; Login; Seal Wizard +44 (0)1254 295400. Smaller sizes only for applications such as needle bearings and grease seal. Furthermore, Nitrile oil seals incorporate exquisite reluctance to hydraulic oils, water, silicone greases, petroleum-based oils and fluids, and alcohols. The Viton® used in the manufacture of Oil Seals is produced by DuPont Performance Elastomers. Seals low pressures as well. Lip Materials Nitrile Buna-N 70 durometer compound is the standard material for our seals and is recommended for a majority of common applications. In some cases, it needs to be used with a supporting ring (also called a retaining ring). … This in combination with a high quality galvanised steel garter spring gives the ERIKS Oil Seal an optimum life. Applications: Fluorosilicone (FVMQ) oil seals incorporate a good low and high-temperature persistence of Silicone (VMQ) and Fluorocarbon’s resistance to solvents, oil, and fuel. Temperature range: between -55°C and +135°C. Radial oil seals are designed for sealing shafts and spindles. Information has been gained from manufacturing partners. Furthermore KLINGERSIL ® is easy to cut, handle and fit.. Material Types This type has to be mounted on the shaft, and has the seal lip on the outside. There are different types of oil seals that fit a different application and surroundings and are made out of different materials. In the following chapter we will give an overview over the most important oil seals and their applications and specifications. Figure 8-13. Metal-cased oil seals are used when installed to a housing bore made of the same material. When the requested R-Duo type is not available, two R-types can be fitted back to back. Applications: Simriz® oil seals are created of an elastomer, which has the widest chemical resistance our of all elastomer materials. Applications: Oil seals produced from Hydrogenated Nitrile (HNBR) present superior sour gas and petroleum oils resistance. Applications: FEP oil seals are an excellent option for static and slow intermittent dynamic applications. Seals pressures to 10 bar (1MPa) depending on the circumstances because it is more compact than type RST. The outside diameter, with inner metal reinforcement case, allows press-fitting in the housing, with sufficient interference on the rubber to provide static sealing. Temperature range: between -10°C and +205°C (intermittent/compound specific between -20°C and +250°C). 1) create an account2) see product prices3) place your order. Some oil is lost along various paths causing oil consumption. The sealing lip with spring provides interference on the shaft for effective sealing. PPE Precision Polymer Engineering - Rubber Seals and Gaskets - Elastomer Seals. M Barnwell Services endeavours to make sure all the content is correct. Also known as a Rotary Shaft Seal, Shaft Seal, Lip Seal, Elastomeric Lip Seal or any variation of these. This is generally used for sealing lubricating oil or grease in rotary shaft applications. Oil seals are rotary shaft seals that close a gap between stationary and moving components and prevent lubricant to escape and thus stop contamination through the clearance. Rubber-cased oil seals are the most common oil seal execution, used when a metal-cased seal has the potential to fail (for example because of thermal expansion). FEP is interfered by a poor memory at low temperatures. Totally enclosed metal casing for extra reinforcement, and a vulcanised rubber sealing lip. Generally, it has been developed as a means of protecting the bearings of rotating shafts. Providing long-lasting sealing efficiency, they consist of a rubber sealing lip, metal case and a spiralled tensioning spring. Oil Seals are also known as a Rotary Shaft Seal, shaft seal, lip seal, elastomeric lip seal or any variation of these. OC-Type oil seals have a sealing lip placed on the outer periphery and they are best used for rotating housing structures. Not available from stock. 1/32″thick sheet is reinforced with graphene for extra solidity. Not yet an ERIKS customer? The piston rod seal , also called U-cup, is the main piston rod seal and is installed inside the end cover of the hydraulic cylinder to prevent leakage of hydraulic oil. Oil seal with flexible reinforced textile-rubber back and rubber sealing lip with garter spring. It is an oil seal with a rotating housing structure and best used for sealing grease. Temperature range: between -15°C and +85°C (intermittent/compound specific between -50°C and +100°C). Here is an overview of other commonly used oil seals with an outside rubber surface: Contact our specialistsWe understand that every application is different and that every project is a fresh challenge. QLFY-TYPE Types of oil seals. Smaller sizes of Type M - only for applications such as needle bearings and grease seal. Temperature range: between -60°C and +180°C (intermittent/compound specific up to +200°C). The DIN 3760 standard specifies dimensions and requirements for materials, marking, use and installation of rotary shaft lip seals used for retaining fluid or grease in unpressurized equipment, Available with or without external dust lip, they are self-retained in an open groove to ISO 6194 and DIN 3760. The sealing element is produced from a high performance Nitrile rubber. It is a simple device for excluding dust, dirt, water or any other contaminant whilst retaining lubricant in rotary shaft equipment. Nitrile rubber - The commonly used material for oil seals Silicone – Used in specific applications where only light loads are applied. In the following chapter we will give an overview over the most important oil seals and their applications and specifications. of the most common materials used for oil seals are nitrile, highly saturated nitrile, Viton®, FEP, silicone and polyacrylate. They are made from a variety of materials to meet the demands of process gas or fluid, temperature and pressure. According to the DIN Standard 3760, category BS. The material has a tensile strength of 3500 psi and can sustain temperatures as high as 325 F. It is made using Hydrogenated Acrylonitrile Butadiene (HNBR) which shows excellent resistant to most oil based chemicals. diameters for example in heavy industry such as roller bearings. M Barnwell Services is the UK’s largest independent stockist, manufacturer, and distributor of fluid sealing products and services.
