NTN bearings play a crucial role in industrial machinery. Any issues with these bearings can lead to costly downtime, equipment damage, and operational inefficiencies. Given that large industrial bearings often represent a significant investment, proper handling and maintenance are essential for maximizing their lifespan and performance.
To ensure optimal function and minimize maintenance costs, it is important to follow the correct procedures during storage, cleaning, inspection, and installation. The longevity of any NTN bearing largely depends on how well it is maintained, especially in harsh environments where heavy loads, dust, and contamination are common.
NTN bearings are typically coated with a protective layer to prevent corrosion, but most bearings are not made from corrosion-resistant materials. During handling and storage, care must be taken to avoid rust or damage. Even small amounts of moisture or oils from bare hands can cause localized etching, leading to premature bearing fatigue.
New or modified NTN bearings usually come with a protective coating and are packaged in paper or cartons. It is advisable to keep them in their original packaging until they are ready for use. Avoid storing bearings directly on concrete floors, as condensation can form and damage the components. Store them on pallets or shelves in a dry area, away from extreme temperature fluctuations.
Always wrap bearings in oil paper or plastic sheeting if available, especially for roller and tapered roller bearings. When removing bearings, always use the appropriate tools and techniques. Improper removal can damage the bearing, shaft, or housing, resulting in expensive repairs. For tight fits, heating the inner ring with a heat lamp or similar device can help ease removal. However, using a torch is not recommended, as it may alter the metal properties and render the bearing unusable.
When installing, never force the bearing or strike it directly with a hammer. Avoid applying pressure through the rolling elements. Always use the right tools and avoid using rags or fibers that might leave behind debris. Keep the bearing and its surroundings clean, as even small particles can increase wear, noise, and vibration.
Never handle NTN bearings directly with your hands. Wash your hands thoroughly before touching them, and apply high-quality mineral oil before installation, especially in dry or hot seasons to prevent rust.
Under certain operating conditions, NTN bearings can outlast traditional bearings, particularly under light loads. When the rolling surfaces (raceways and rolling elements) are properly lubricated and protected from contaminants, they can perform exceptionally well. In reality, the so-called "eternal" life of an NTN bearing is more about proper maintenance than inherent durability.
