China Factory Supply FKM NBR Skeleton Oil Seal

　　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.
