Smörjfett

Smörjfett, often translated as lubricating grease, is a semi-solid lubricant composed of a base oil, a thickener, and additives. The base oil provides the lubrication, while the thickener gives the grease its structure, preventing the oil from separating and flowing away. Additives are incorporated to enhance specific properties such as extreme pressure resistance, rust protection, or oxidation stability.

The primary function of smörjfett is to reduce friction and wear between moving parts. It achieves this by forming a film between surfaces that prevents direct contact. Unlike lubricating oils, greases tend to stay in place, making them ideal for applications where a liquid lubricant would be prone to leakage or where long-term lubrication is required without frequent reapplication.

Common applications for smörjfett include bearings, gears, hinges, and chassis lubrication in vehicles, industrial machinery, and many other mechanical systems. The choice of smörjfett depends on factors such as operating temperature, load, speed, and environmental conditions. Different types of thickeners, such as lithium, calcium, or polyurea, are used to create greases with varying characteristics to suit these diverse requirements.
