Products Description
Bearing dust cover NBR TC oil seal is a high-performance bearing seal component that effectively protects bearings from external contamination and damage. It is widely used in bearing protection of various mechanical equipment, such as motors, pumps, gearboxes, etc. It can effectively extend the service life of bearings and reduce maintenance costs, and it is particularly advantageous when used in harsh environments.
Bearing Dust Cover NBR TC Oil Seal-Mechanical Sealing Solutions
Structural Features
- Skeleton structure: TC oil seals are usually made of a metal skeleton, which provides the necessary strength and shape retention for the oil seal.
- Rubber coating: The skeleton is covered with rubber material, usually NBR (nitrile rubber), with good elasticity and sealing performance.
- Main sealing lip: This is the part of the oil seal that contacts the rotating shaft and is responsible for preventing the leakage of lubricating oil. The main sealing lip is usually designed with a certain angle to adapt to different working conditions.
- Spring: The spring integrated into the main sealing lip provides continuous and uniform pressure to the sealing lip, ensuring good contact with the rotating shaft and maintaining sealing performance even at high speeds.
- Dustproof lip: This is another important component of the oil seal. It is located opposite the main sealing lip and is used to prevent dust and other contaminants from entering the interior of the machine.
- Double lip design: Some TC oil seals adopt a double lip design, in which one lip is responsible for sealing and the other lip is responsible for dust prevention, thus providing double protection.
- Material diversity: Depending on the application environment, TC oil seals can use different materials, such as NBR, FKM, silicone, ACM, HNBR, etc., to adapt to different temperatures, chemical media, and pressure conditions.
