Regular maintenance and inspection of shaft oil seals are essential to ensure their proper functioning and prevent costly downtime and repairs. Signs of a worn or damaged seal include oil leaks, increased noise or vibration, and decreased efficiency. If any of these symptoms are detected, it is important to replace the seal promptly to avoid further damage to the machinery.

Rubber oil seals are widely used in various applications due to their versatility, durability, and resistance to oil and other fluids. These seals are designed to provide effective sealing solutions for rotating or reciprocating shafts, preventing the escape of lubricants and the entry of contaminants. Rubber oil seals play a crucial role in maintaining the efficiency and longevity of industrial machinery, automotive engines, and other equipment by ensuring proper lubrication and protection of internal components.
Heat and attrition are generated by the parts moving against each other. The sealing function can only be ensured if an intentional defined leakage of oil is able to exit for seal lubrication, preventing seal wear and possible failure, while a tight static seal between shaft and sealing lip must be assured when the shaft is stationary.
- Double Lip, No Spring: This design is also springless and is generally used to seal non-pressure media like grease. It protects against both internal and external media.

When choosing seal materials, it is critical to evaluate the environment and application. Common seal materials include:
Silicone
Wide temperature range
Commonly used in low temperature applications
Very prone to mechanical damage during fitting
