Difference between TA oil seal and TB oil seal
TA oil seals and TB oil seals are rotary oil seals, which are mainly used to prevent the leakage of lubricants and prevent the intrusion of external pollutants, but there are some differences in structure and application scenarios between them: Structural features: TA oil seal: has a double lip design, that is, there are two sealing lips, one of which is the main lip to prevent the leakage of lubricants, and the other is the secondary lip to block the entry of external contaminants. TA oil seal is installed with a spring inside, and adopts a double iron shell structure (that is, the outer iron shell wraps the inner shell), such a design increases the outer diameter rigidity of the oil seal, especially for large caliber applications. TB oil seal : Also designed for two lips, equipped with mounting spring, but unlike TA oil seal, TB oil seal only has a single shell iron shell, no inner shell wrap. Such a structure may not be as rigid as TA oil seals in outer diameter, but may have adv
