A dust lip seal, often made of elastomers or polymers, is designed to fit closely around rotating shafts or in applications where parts move relative to one another. The primary function of this component is to create a barrier against external contaminants while allowing internal lubrication to remain intact. Typically, dust lip seals feature an outer lip that provides the necessary seal against particles and a secondary inner lip that retains lubricants within the assembly.

In summary, the 20x35x7 oil seal is more than just a small component; it represents a fundamental element of modern machinery and equipment. Its ability to prevent fluid leaks while protecting against contaminants underscores its significance across various industries. Choosing the right oil seal not only improves the performance and longevity of machinery but also contributes to overall operational efficiency. Whether in automotive applications, industrial settings, or aerospace, the 20x35x7 oil seal is poised to remain an indispensable part of engineering solutions for years to come.

Typically made from elastomeric materials like nitrile rubber (NBR), fluorocarbon rubber (FKM), or silicone, oil seals are engineered to withstand varying temperatures, pressures, and chemical environments. The choice of material affects their performance characteristics, including resistance to wear, deformation, and aging. The design of the oil seal includes a sealing lip, which provides a barrier against leaks while maintaining a low coefficient of friction against the shaft.
