Oil Seal

Lubricating grease and oil seals are both essential components in machinery, but they serve different purposes and have distinct characteristics.

Lubricating grease is a semi-fluid substance used to reduce friction between moving mechanical parts. It is typically composed of a base oil, a thickener, and additives. The base oil provides the lubrication, the thickener gives the grease its consistency, and the additives enhance performance under specific conditions.

On the other hand, oil seals, also known as shaft seals, are used to prevent the leakage of lubricants from gaps within machines and bearings. They are typically made from materials like rubber, silicone, or polyurethane and are designed to fit tightly between rotating and stationary components.

In summary, while lubricating grease is used to minimize friction and wear, oil seals are used to prevent the escape of lubricants and the ingress of contaminants. Both are crucial for the efficient operation and longevity of machinery.
