Hebei Hankai double lip wiper seal

Typically made from elastomeric materials like nitrile rubber (NBR), fluorocarbon rubber (FKM), or silicone, oil seals are engineered to withstand varying temperatures, pressures, and chemical environments. The choice of material affects their performance characteristics, including resistance to wear, deformation, and aging. The design of the oil seal includes a sealing lip, which provides a barrier against leaks while maintaining a low coefficient of friction against the shaft.

1. Lubrication Retention The primary function of a grease seal is to retain the lubricating grease within the bearing. This grease is crucial for reducing friction, minimizing wear, and ensuring that the bearing operates smoothly. When grease escapes, the bearing can run dry, leading to overheating and potential failure.

- Manufacturing Machinery used in factories, particularly those dealing with raw materials like wood, metal, or plastic, often incorporates dust proof seals to enhance durability.

When replacing wiper oil seals, it is important to select the right type for the specific application. Factors such as temperature, pressure, and the type of fluid being contained should all be considered when choosing the appropriate seal. Additionally, proper installation is critical; even a small misalignment can lead to premature failure of the seal.

2. Design Variety These seals come in different designs, such as lip seals, mechanical seals, and cartridge seals, each suited for specific applications and performance requirements.
