Akseltætninger

Akseltætninger, often referred to as shaft seals, are mechanical devices designed to prevent leakage between a rotating shaft and a stationary housing. Their primary function is to contain lubricants, such as oil or grease, within a system while simultaneously preventing the ingress of external contaminants like dirt, dust, and moisture. This dual purpose is crucial for maintaining the integrity and operational efficiency of machinery.

These seals are commonly found in a wide range of applications, including automotive components like engines and transmissions, industrial machinery, pumps, gearboxes, and hydraulic systems. The design of an akseltætning typically involves a flexible sealing lip or element that maintains contact with the rotating shaft. This contact creates a barrier that resists the flow of fluids and particles.

Various materials are used in the construction of akseltætninger, with common choices including rubber compounds like NBR (nitrile butadiene rubber) and FKM (fluoroelastomer), as well as PTFE (polytetrafluoroethylene) and metal. The selection of material depends heavily on the operating environment, including temperature, pressure, and the type of fluid being sealed. Factors such as shaft speed, temperature, and the presence of abrasive contaminants also influence the design and material choice to ensure optimal performance and longevity.
