Which of the following contributes to the longevity of a friction bearing?

Regular lubrication is essential for the longevity of a friction bearing because it reduces the coefficient of friction between the bearing surfaces. This lubrication minimizes wear and tear, helps to dissipate heat generated during operation, and prevents corrosion. A well-lubricated bearing operates more smoothly and effectively, leading to a longer service life. By ensuring a sufficient and consistent supply of lubricant, you enhance the bearing's ability to handle loads while reducing the risk of overheating and mechanical failure. Proper lubrication practices contribute significantly to maintaining the integrity and operational efficiency of friction bearings over time.
