- TC oil seals are a type of radial shaft seal that plays a crucial role in preventing fluid leakage and protecting machinery from contaminants. - A TC oil seal consists of a rubber-coated metal cage, a main sealing lip with an integrated spring, and an additional sealing lip. The function of the rubber seal is to prevent leakage of the medium along moving parts. - TC oil seals are used by machinery to seal oil. Based on sealing function, characteristics, structure type, working state, and sealing mechanism, skeleton oil seals can be divided into various forms and different names, including the TC type. - These oil seals are made of NBR (nitrile rubber). NBR is the most commonly used sealing material and offers strong heat resistance along with strong resistance to oils, salt solutions, hydraulic fluids, gasoline, diesel, and other gasoline products. Applications: Gearboxes, hydraulic systems, engines, industrial machinery, and related equipment.
