Rubber Oil Seal

Our produce oil seal is an improvement of TC. The features are:

1,the outside annular thread:

Refer to technical academic crystal of Europe (Germany)=> strengthen the theory of preventing outside leakage to design and produce.Easy and convenient to install
Annular multilayer seal---multi-checkpoints and line-contact. The sealing effect is much better than others.
The design angle of ring-like thread and other questions about annular threads are our intellectual property rights. They are unopened temporarily.
2,the inside three-lips mouth:

To prevent from leaking inside more efficiently.
When the axle rotates, it can increase its fitness and stability of oil seal and improve the effect of sealing.
The micro-contact auxiliary lip is added in the middle (increasing not much resistance).To protect the primary lip (function)
According to the standpoint of structural mechanics, this design may support the primary lip, and makes it not turn over and swing easily (the sealing strength of the lips is more centralized, which increases stability of sealing and prolongs its life)
The auto-stripping production makes the primary lip more stable. This also is another breakthrough.
