pitkäöljyiset

Pitkäöljyiset is a Finnish term that translates to "long-oiled" and typically refers to a category of lubricants. These are generally viscous oils designed for applications requiring extended lubrication periods or operating under high load and temperature conditions. The "long-oiled" designation emphasizes their ability to maintain lubricating properties for a significant duration, reducing the need for frequent reapplication.

The formulation of pitkäöljyiset lubricants often involves base oils with higher viscosity indices, meaning their viscosity changes less with temperature fluctuations. Additives such as extreme pressure (EP) agents, anti-wear compounds, and rust inhibitors are commonly incorporated to enhance their performance and protect the lubricated surfaces. These lubricants are often used in industrial machinery, heavy-duty equipment, and other demanding environments where standard oils might degrade too quickly or fail to provide adequate protection.

Applications can include gears, bearings, chains, and sliding surfaces that experience continuous or intermittent heavy stress. The extended service life offered by pitkäöljyiset lubricants can contribute to reduced maintenance downtime and increased operational efficiency. The specific composition and properties of a pitkäöljyiset lubricant will vary depending on its intended use and the manufacturer's specifications.
