　　Skeleton oil seals also known as radial shaft seals, play a pivotal role in various mechanical systems. They prevent the leakage of lubricants and the intrusion of contaminants. But what sets skeleton oil seals apart? This article aims to explore the unique structural characteristics of skeleton oil seals.

　　Understanding Skeleton Oil Seals:

　　Skeleton oil seals are named for their distinctive structure, which includes a metal casing or “skeleton” that provides rigidity and shape to the seal. This metal casing is usually coated with an elastomer for better sealing.

　　Structural Characteristics of Skeleton Oil Seals:

　　1. Metal Casing: The metal casing provides the seal with its basic shape and rigidity. It helps the seal maintain its form under pressure and during installation.

　　2. Elastomer Coating: The elastomer coating on the metal casing enhances the sealing capability of the oil seal. It is designed to be flexible and conform to the shape of the shaft or bore it is sealing.

　　3. Sealing Lip: The sealing lip is the part of the seal that comes into direct contact with the shaft. It is typically made from a material that is resistant to wear and tear and compatible with the lubricant.

　　4. Garter Spring: Some skeleton oil seals feature a garter spring. This spring helps maintain the sealing force of the lip against the shaft, especially during periods of no or low pressure.

　　The unique structural characteristics of skeleton oil seals, including the metal casing, elastomer coating, sealing lip, and optional garter spring, contribute to their effectiveness in preventing lubricant leakage and blocking contaminants. Understanding these characteristics can help in selecting the right oil seal for your needs.
