Bearing service life refers to the number of revolutions or hours a bearing undergoes under a certain load before pitting occurs. Within this service life, initial fatigue damage should occur on any of its bearing rings or rolling elements. However, in our daily practical use, it is clearly observed that bearings with identical appearances under the same working conditions have significantly different actual service lives. Many factors affect bearing service life. Today, we will briefly introduce the impact of bearing maintenance and rust prevention on bearing service life.

At Ningbo Demy (D&M) Bearings Co., Ltd., our team has been closely observing the transformation of high-speed industrial machinery, and we are witnessing a significant shift toward ceramic bearings.

At Ningbo Demy (D&M) Bearings Co., Ltd., we specialize in engineering high temperature bearings that can withstand extreme thermal stress while maintaining mechanical performance.

In industrial environments where machinery operates under extreme conditions, bearing performance determines both reliability and safety.

In modern mechanical systems, the efficiency, reliability, and longevity of equipment heavily rely on the performance of special material bearings.

In the world of automotive engineering, every moving part matters. Among the most crucial yet often overlooked components are Tensioner Bearings — precision parts that ensure the timing belt or serpentine belt operates smoothly, quietly, and efficiently. Without them, engines would lose synchronization, leading to poor performance or even severe mechanical damage. I've seen many customers underestimate the importance of these bearings, but once they experience the benefits firsthand, they understand why they're indispensable.
