The integrated combined structure (box oil seal structure), the inner and outer components of the oil seal form a self sealing, and the inner and outer components cooperate with each other to realize the sealing of lubricating oil and the protection of external foreign matters;

The main sealing lip is matched with the shaft surface of the inner framework to form a seal for the lubricating oil. Since the oil seal is self matched to form a seal, it is conducive to quality control and reduces the requirements for the surface roughness and hardness of the oil seal seat ring;

The inner and outer oil seal components cooperate with each other to form a labyrinth protection channel, extend the protection channel and multi-channel protection lips, which can effectively prevent the invasion of external foreign matters;

The labyrinth channel is conducive to the storage of grease, and the protective lip is optimized to ensure long-term protective effect with low wear during operation;

The foreign body protection lip is a combination of radial seal and axial seal, which improves the reliability of protection;

The integrated combined structure improves the self-protection ability of the oil seal and reduces the possibility of oil seal pollution and damage in the storage, transportation and assembly of the oil seal;

Since the oil seal is a self sealing structure, the requirements for relevant mating parts are reduced and the oil seal seat ring is not damaged. Even if the oil seal is replaced later, the sealing performance will not be affected.
