Oil seals are essential components used to prevent leaks of lubricating oils in mechanical systems. Their main function is to seal the edges of lubricated parts, ensuring that oil remains contained and does not escape. The most common type of oil seal is the TC oil seal, characterized by its double lip and self-tightening spring under a rubber cover. This type is often what is referred to when discussing oil seals in general.

Oil seals can be made from various materials including Nitrile rubber (NBR), fluorine rubber (FKM), silicone rubber, acrylic rubber, polyurethane, and polytetrafluoroethylene (PTFE).

1. NBR

Nitrile rubber is celebrated for its heat resistance, wear durability, and compatibility with various lubricants. It operates effectively within a temperature range of -30 to 120 degrees Celsius, although it is not suitable for use with phosphate hydraulic oils or extreme pressure gear oils.

2. Polyacrylate rubber (ACM)

This material boasts excellent resistance to oil, heat, and abrasion while maintaining integrity against ozone and ultraviolet radiation. It performs well in extreme pressure situations and operates effectively in a temperature range of -30 to 150 degrees Celsius.

3. Fluororubber (FPM)

Fluororubber exhibits superior aging, heat, and oil resistance, applicable with nearly all lubricants and fuels. It maintains performance in temperatures ranging from -20 to 250 degrees Celsius but may struggle to retain performance under high temperature due to compression issues.

4. Silicone rubber

Known for outstanding temperature tolerance, silicone rubber can function at 150 degrees Celsius without performance degradation and can withstand up to 200 degrees Celsius for extended periods.

5. Teflon

Teflon is recognized for its exceptional thermal and chemical stability, self-lubrication, and friction reduction capabilities. It can operate normally at temperatures ranging from -200 to 300 degrees Celsius and demonstrates excellent resistance to most chemicals.

The frequent choice of materials like Nitrile butadiene rubber (NBR) and fluorine rubber (FBR) is prevalent due to their cost-effectiveness and improved performance characteristics. However, the development of products such as PTFE oil seals signifies a shift toward more advanced solutions in sealing technology.

Note: When selecting the material for an oil seal, it is crucial to consider material compatibility with the operating medium, temperature range adaptability, and the lip edge's capability to follow a rotating shaft at high speeds. Selecting appropriate oil seal materials is critical as the conditions of use significantly depend on these factors, including the specific range for NBR, ACM, FPM, and other materials.
