NAF bearing seals prevent contaminants from entering the bearing by creating a physical barrier between the bearing and its surroundings. The seals are designed to fit tightly around the bearing, preventing dust, dirt, water, and other contaminants from infiltrating the bearing raceways. In addition to creating a barrier, bearing seals may also include a grease labyrinth or lip seal that helps to retain lubricant inside the bearing, preventing contamination and reducing friction. The seals are typically made of high-quality materials that are resistant to wear and corrosion, ensuring that they continue to protect the bearing over time.
