Application area for radial shaft seals
Applications that require perfect sealing and protection between the shaft rotating in an oily or greasy medium and the outside use radial shaft seals, also known as simering or shaft/oil seals. These seals are essential to prevent leakage of fluids, oils and other substances while allowing the shaft to move.
In addition to the traditional NBR material radial shaft seals, KTT Sealing Technologies also manufactures seals in FKM (FPM, Viton), HNBR, EPDM, silicone (MVQ, VMQ) and can also provide customized solutions for our customers.
When choosing a seal, an important consideration is the choice of material for the specific operating medium, temperature, oil pressure and shaft circumferential speed. We recommend Silicone (VMQ) and Viton (FKM, FPM) materials for high-speed applications. Below are some typical applications.
Automotive
Radial shaft seals are used in engines, transmissions and wheel axles to prevent oil leakage.
Mechanical industry
These seals are used in many parts of industrial machines and equipment, for example in the shafts of pumps, compressors and rotating machines.
Food industry
In the food industry, especially in machines where hygiene and a clean environment are important, radial shaft seals are used, for example, in the shafts of mixers and packaging machines. The FDA means in product name the fulfillment for regulation of Food and Drug Administration and these products are surely applicable in food industry.
Proper selection and maintenance of oil seals is key to ensuring efficient and reliable operation of machines.
