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
Applications can include gears, bearings, chains, and sliding surfaces that experience continuous or intermittent heavy stress.
