Metal Dust Lip Skeleton Oil Seal Rubber NBR FKM Oil Seals Rotary Shaft Oil Sealing

Structure
TB oil seals usually consist of a metal housing that provides strength and stiffness. An internal spring-loaded sealing lip ensures tight contact with the shaft.

Materials
Common materials used for TB oil seals are nitrile rubber (NBR) and fluoroelastomer (FKM). NBR has good mechanical properties and abrasion resistance, while FKM has excellent chemical and heat resistance and is suitable for use in high-temperature environments.

Features
TB oil seals have good sealing performance and can effectively prevent oil leakage. It is adaptable to machine vibration and spindle eccentricity. Small axial dimensions, easy machining, and compact machine structure.

Application areas
They are widely used in automotive engines and transmissions as well as in industrial machinery such as pumps and motors. In the automotive field, they prevent oil leaks and keep engines and transmissions running properly. In industrial machinery, they ensure proper operation by preventing lubricant leakage.

Advantages and disadvantages
The advantages are simple structure, easy to manufacture, light weight and low material consumption. They also have a long service life. However, in some extremely harsh environments, such as extreme high temperatures or high pressures beyond the rated range, their sealing performance may be compromised. In addition, in certain corrosive environments, the metal outer cage may corrode if not properly protected.
