The surface roughness of the counterface on the shaft of rotary applications should lie between Ra 0,2 and 0,8 µm, if the maximum permissible circumferential speeds are to be used. Sealing is provided by the surface tension of the hydrodynamic oil film between the seal flattened area and the shaft. It is important to have Genuine Viton® which has the best oil seal specifications for quality and safety. The spring helps keep the sealing lip in contact with the shaft. Good heat and compression set resistance. SHAFT BORE WIDTH PART NO. Quality assurance for the best materials is a musthave. The split in an elastomeric seal facilitates assembly. Garlock Oil Seals by Shaft Size All dimensions are in inches. PEEK has superior chemical resistance, is inert to all common solvents and resists a wide range of organic and inorganic liquids. Other material available on inquiry only. To achieve a reliable seal and sufficiently long service life, the surface of the seal counterface should have a hardness of at least 55 HRC or 600 HV.

V-ring seals are all rubber seals used primarily to exclude dirt and other contaminants. An oil seal can also called flexible lip, radial lip, or rotary shaft seal. Where possible, these materials have been categorized into the generic equivalent or material family. Good resistance to sunlight, weathering and ozone. Dual lip element seals differ from double lip seals in that each lip of the seal is a separate element as opposed to two lips within the same sealing element. This dimension is commonly used for seals such as V-rings, back-up rings, piston rings, and pipe seals.

Oil seals work to prevent leakage of sealed objects such as lubricants from inside and also to prevent the entry of dust and contaminants from outside. Nitrile has good mechanical properties when compared with other elastomers and high wear resistance. Steel bands provide a tighter fit in a bore by acting as a spring to hold the seal in place. This dimension refers to the housing bore diameter or the seal outside diameter. Some bearing isolators are of labyrinth construction while others use O-rings or other positive seals. Trade names include Therban® (Mobay), Tornac® (Polysar), and Zetpol® (Nippon Zeon Company). Seal may have a garter spring, however. Copyright © 2021 ERIKS nv. Specification test for Viton oil seal. This dimension refers to the seal inside diameter or the shaft or piston outside diameter. Many labyrinth seals are comprised of a rotor (rotating) and stator (stationary) member with a radial gap between the two members. Four or More Lip Oil Seal U-ring / Block Vee Ring Also called flexible lip, radial lip, or rotary shaft seals. Widely used with most oils, hydraulic fluids, and alcohol. Viton is a synthetic rubber and fluoropolymer elastomer used in O-rings, seals and other moulded products. Nylon, comprising several grades of polyamides, is a general-purpose material in wide use; it is tough and resistant and has good pressure ratings. (NOTE: The urethanes of the plastics industry are so named because the repeating units of their structures resemble the chemical urethane.) Metal cased seals are often coated with rubber. V-rings are considered external lip seals. Any break in the meniscus will result in leakage. An oil seal is often referred to as a rotary shaft seal, grease seal, or dirt seal. The actual seal width is approximately 0,4 to 0,8 mm (0.016 to 0.032 in.) Neoprene also offers resistance to damage caused by flexing and twisting. Also referred to as a shaft seal.

Metal cased seals are often coated with rubber. Brand names include: Celcon (Hoechst Celanese), Delrin (DuPont), Thermocomp (LNP), Ultraform (BASF). API FA-4 oils are designed to provide enhanced protection against oil oxidation, viscosity loss due to shear, and oil aeration as well as protection against catalyst poisoning, particulate filter blocking, engine wear, piston deposits, degradation of low- and high-temperature properties, … Specs: Radial shaft seal with outer metal case, spring loaded sealing lip and additional dust lip. Metal Cased Oil Seals. Oil seals are functional parts used to seal oil. The seal is fit onto a shaft with the sealing lip contacting the housing bore. Another form of labyrinth seal is a laminar sealing ring, which uses a series of flat metal washer-like rings of varying diameters to create a labyrinth seal. Suggested operating temperature (-45° to 230° F). Maximum operating speed is generally given as ft/min or m/sec. Double Lip Rubber Cover (High Pressure) Viton ® Oil Seal. The one thing they all have in common is that they all operate on a principle of positive clearance (i.e., no rubbing against the shaft or housing). These features make the Seal handbook your most valued tool in the selection, application, trouble detection and specification of SKF fluid sealing devices. This is the full required range of ambient operating temperature. Imperial Oil Seals.
