Metal cased seals are often coated with rubber. Consult with manufacturer for proprietary material specifications. In precision bearings, oil seals help prevent lubricants from escaping the bearings or a specific area. RubberTechnology.info » Rubber products » Seals » Viton oil seal specification. As each country has different regulations for the use of steel, we make two tables to let you understand easier. Also called U-packings or Block Vee packings. Suggested operating temperature (-45° to 230° F). Studies have shown this area to be one of the major causes of premature seal failure. Products returned as matches will meet all specified criteria. It has poor resistance to petroleum oils and fuel. Nitrile has good mechanical properties when compared with other elastomers and high wear resistance. All matching products will have a value greater than or equal to the specified value. Today's industries operate under extreme conditions. Plastics and elastomers are polymers. This Seal handbook contains complete product data for the selection of SKF shaft seals, Speedi-Sleeves ®, … Some bearing isolators are of labyrinth construction while others use O-rings or other positive seals.

Viton seals are well known for excellent heat resistance. In machine components, oil seals help prevent abrasives, corrosive moisture and other harmful contaminants from entering machinery. Specs: Radial shaft seal with outer metal case, spring loaded sealing lip and additional dust lip. 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). national oil seal. "Required" and "Must Not Have" criteria limit returned Suggested operating temperatures from (-40° to 300° F). The most commonly used oil seals in most applications are rubber cased or metal cased oil seals. They are available in imperial and metric dimensions for both single- and double-lip design. Acetal polymers are semi-crystalline. All products with ANY of the selected attributes will be returned as matches. These seals generally do not perform well at low operating speeds. The mechanical and physical properties are very similar to silicone. Neoprene remains useful over a wide temperature range, displays outstanding physical toughness, and resists burning inherently better than exclusively hydrocarbon rubbers. An oil seal that has one flexible sealing lip. User may specify either, both, or neither of the "At Least" and "No More Than" values. A wide variety of oil seal specification options are available to you, such as electric. These seals are primarily used for rotary applications only. ), Labyrinth Oil Seals - Big MTBF & MTBPM Increases, Video: CinchSeal Rotary Shaft Seal Overview, View More Product Announcements for Oil Seals and Grease Seals.

They also help stop intermixture of two different mediums, such as lubricating oil and water. A synthetic rubber that resists degradation from sun, ozone, and weather. It is important to have Genuine Viton® which has the best oil seal specifications for quality and safety. (NOTE: The urethanes of the plastics industry are so named because the repeating units of their structures resemble the chemical urethane.) Many solutions can be found in this ERIKS technical oil-seal manual. Material: NBR (Natural Rubber), Plain Steel case, Spring Steel spring. New ACEA oil specifications were issued in 1998, 1999, 2002, 2004, 2007, 2008, 2010, 2012 and 2016. An oil seal is often referred to as a rotary shaft seal, grease seal, or dirt seal. Common configurations include single lip, double lip, triple lip, and four or more lips. The actual seal width is approximately 0,4 to 0,8 mm (0.016 to 0.032 in.) This dimension refers to the axial cross section, or thickness, of the seal. VIASY, BABSL V, AS-P Viton Specs: Radial shaft seal with rubber covered O.D.
