These seals are used where it is desirable to have a back-up seal incorporated into one seal case or shell. 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 seals generally do not perform well at low operating speeds. Nitrile is not resistant to weathering and ozone. ERIKS has tested the heat resistance at 250°C for 70 hours with perfect results. Good resistance to sunlight, weathering and ozone. Material: NBR (Natural Rubber), Plain Steel case, Spring Steel spring. These seals are primarily used for rotary applications only. They offer a high degree of oil, ozone, UV, and weather resistance along with good low temperature flexibility. User may specify either, both, or neither of the limits in a "From - To" range; when both are specified, matching products will cover entire range. VIASY, BABSL V, AS-P Viton Specs: Radial shaft seal with rubber covered O.D. B1SL, TB, WBS, BC. An axial seal seals axially against a housing or machine component. Oil seals are functional parts used to seal oil. Max Temperature: -40°C/-40°F – 100°C/ 212°F. Metal cased seals are often coated with rubber. 1.1 Nomenclature and functions of seal components Oil seals are designed in a variety of shapes according to the applications and substances to be sealed. We have 2000 standard, ISO 6194-1 sizes available from stock. The meniscus acts as an interface between the outside air and the fluid. Suggested operating temperature (-45° to 230° F). A split rigid (metallic) seal is similar in functionality to a piston ring. A Block Vee seal is more compact and has better performance characteristics under high pressure than a U-ring. Suggested operating temperature (-25° to 350° F). Metal Cased Oil Seals. Download Rotary Seals . 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. Seal is symmetrical and works equally well as a rod or a piston seal. An oil seal that has two flexible sealing lips. This Seal handbook contains complete product data for the selection of SKF shaft seals, Speedi-Sleeves ®, … The gap must be larger than the radial clearance of the bearing being sealed. Polyacrylate elastomers are well suited for use with extreme pressure (EP) lubricants and have high resistance to oxidation and ozone. Oil seals and grease seals have a flexible lip that rubs against a shaft or housing to prevent the leakage or ingress of fluids and dirt. Piston seals are radial seals. In machine components, oil seals help prevent abrasives, corrosive moisture and other harmful contaminants from entering machinery. matches as specified. Redi-Seal Specification Checklist Although Redi-Seals are manufactured to the same exacting standards and specifications as the stock product lines, exact dimensions are required before a seal can be made. Various lip materials are also available to best suit design requirements such as temperature and chemical resistance. © ERIKS nv, 2021. Oil thickness must be between 1 and 3 um to avoid leakage. Seal is spring-energized by addition of a garter spring, meander spring, canted coil spring or helical seal spring. Polyacrylates are not recommended for dry running applications. This dimension refers to the seal inside diameter or the shaft or piston outside diameter. 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. Suggested operating temperature (-100° to 350° F). We develop any material required in our own laboratories. HOW TO USE THIS CATALOG The seals listed in this catalog are arranged by shaft size and part number. Oil seals are used to retain grease in a case or housing.

Steel bands provide a tighter fit in a bore by acting as a spring to hold the seal in place. V-ring seals are all rubber seals used primarily to exclude dirt and other contaminants. V-rings stretch over a shaft and seal against the side of a housing or other machine component. Today's industries operate under extreme conditions. There are many different styles of clearance, or labyrinth seals. In addition, the operating speed and temperature must be considered when using a labyrinth seal. This is the full required range of ambient operating temperature. They also prevent the entry of dust from the outside. Acetals suffer from outgassing problems at elevated temperatures, and are brittle at low temperatures. Metal cased seals are often coated with rubber.
