When discussing oil seals, several factors come into play. First and foremost is the material used in the seal's construction. Common materials include rubber, polyurethane, and fluorocarbon, each having its own advantages and disadvantages. For instance, rubber seals are generally cost-effective and can work well under moderate conditions, while fluorocarbon seals are exceptionally resistant to heat and chemicals, making them ideal for high-performance applications.

2. Contamination Control Besides maintaining pressure, seals also protect the internal components from dirt, dust, and other contaminants that can enter the cylinder. A robust sealing system ensures that these foreign particles do not compromise the cylinder's functionality, which can drastically affect the overall performance and lifespan of the hydraulic system.

In addition to preventing oil leakage, oil seals for rotating shafts also help to keep out contaminants such as dirt, dust, and water. This is important for maintaining the cleanliness of the machinery and preventing damage to the moving parts. By creating a secure barrier against external elements, oil seals help to prolong the life of the machinery and reduce the need for maintenance and repairs.
