Oil Seals

Oil Seals, Radial Oil Seals Oil Seals, also known as radial oil seals, radial shaft seals or rotary shaft lip seals, are round sealing devices used to seal between two machine parts that rotate relative to each other. They are used to seal lubrication in and contamination out, or to separate dissimilar media. Oil Seal Design Although there are many styles of Oil Seals, they all generally consist of a flexible rubber lip bonded to a rigid metal case. Most also contain a third element – a garter spring – fitted into the rubber lip to provide additional sealing force, both initially and over the life of the seal. The total radial force of the sealing lip is a function of the rubber pre-tension, coupled with the tensile spring force. The sealing lip may be lathe cut or ready molded, and may feature molded-in hydrodynamic aids to assist sealing in demanding applications. The metal case may be exposed or have rubber molded around it for ease of assembly or improved static sealing. Yimai Sealing Solutions offers state-of-the-art Oil Seal design standards based on many years of experience in a wide range of application fields. Radial Oil Seal Radial oil seals are designed for sealing shafts and spindles. Providing long-lasting sealing efficiency, they consist of a rubber sealing lip, metal case and a spiralled tensioning spring. Available with or without external dust lip, they are self-retained in an open groove to ISO 6194 and DIN 3760. Versions come without the spring for grease applications, for use as a scraper or for helical movement.
