double lip oil seal

4. Wipers Wipers or scrapers are designed to keep contaminants away from the seals, reducing wear and prolonging the life of the hydraulic system.

Seal dust primarily accumulates in areas with high seal concentrations, such as beaches and ice floes. As seals molt and shed skin, fur, and other organic materials, these particles become airborne, mixing with the surrounding environment. The composition of seal dust includes not only the biological debris from the seals but also microorganisms and other particulates that they may encounter in their habitat. This composition can vary significantly depending on the species of seals present, their diet, and the environmental conditions of the area.

The first figure, 22%, typically refers to the efficiency rate of a sealing system. In many mechanical applications, oil seals operate under various conditions and stresses. A 22% efficiency rating means that seals must be capable of withstanding fluctuations in temperature and pressure, ensuring that the lubricating oil remains contained. A higher efficiency rate often translates to a longer lifespan for machinery, thus saving costs in maintenance and potential downtime.

1. Material Selection High pressure rotary seals are made from various materials, including elastomers, polymers, and metals. The choice of material depends on factors like pressure, temperature, and fluid compatibility.
